Lightning takes down Amazon cloud

Online book seller and cloud-computing provider Amazon.com has blamed the latest outage to hit its Elastic Compute Cloud service on a lightning strike at one of its data center.
##CONTINUE##
In a statement posted on the forums section of Amazon's Web-services site, the online retailer addressed concerns from some US customers who said their use of the EC2 service had been disrupted at around 6:30pm US Pacific Time on Wednesday. "A lightning storm caused damage to a single Power Distribution Unit (PDU) in a single Availability Zone. While most instances were unaffected, a set of racks does not currently have power, so the instances on those racks are down," the company said in a posting on the site.

The disruption lasted around four hours, during which time Amazon asked any affected customers to use alternative parts of the network. "Users with affected instances can launch replacement instances in any of the US Region Availability Zones or wait until their instance(s) are restored," Amazon said.

The company later attributed the outage to a problem on one "availability zone" and that the outage was localized. "We would like to reconfirm that this issue was limited to the single Availability Zone where this power issue occurred, and that a very small percentage of instances in that AZ were affected; this was not a generalized service issue," Amazon said.

Despite acknowledging that Amazon had dealt with the issue fairly efficiently, one user was concerned that a single lightning strike was able to bring down the service, if only in a limited way. "I was under the impression that your architecture had more resiliency built into it. Yes we can use multiple availability zones to help with a single point of failure, but I thought that even within a single availability zone there was not a single point of failure for hardware/power," the user posted to the Amazon forum.

The EC2 service provides customers with virtual access to Amazon's computing infrastructure, using virtual machines that can be created using the Xen virtualization platform. First launched in a limited beta in August 2006, the EC2 service went fully live in October 2008.

Not including the latest issue, the service has suffered two major disruptions during that time in February 2008 and October 2007. In June 2008, Amazon's main retail site suffered an outage which the company blamed on the complexity of its own systems.

A series of outages that have hit other online or cloud computing services including Google's Gmail and other applications over recent months have led some critics to question whether the cloud approach to computing is really capable of providing the resilience required by enterprise users.

In mid-May, Google services were hit by an outage which apparently affected one in 10 of its users. In January this year, software-as-a-service (SaaS) pioneer Salesforce.com experienced an outage that disrupted all its customers for approximately an hour.

Amazon S3 Lets Customers Ship Big Data

Amazon's S3 cloud storage service has a new option, called AWS Import/Export, for quickly uploading large amounts of information to its data centers. It uses a well-developed, multimodal content delivery network that can transmit terabytes of data faster than a T-3 leased line.
##CONTINUE##
The fact that this network is based on jets, trucks and messengers with walkie-talkies doesn't make it any less useful to enterprises, many of which have been using overnight shipping services for backups for several years, according to 451 Group analyst Henry Baltazar. Just make sure the data's encrypted in case it falls off the back of a truck or otherwise gets lost, he said.

AWS (Amazon Web Services) described the new service in a recent blog posting. AWS Import/Export from Amazon Web Services lets customers send virtually unlimited amounts of data to Amazon when they want to start using S3 for the first time, back up their content offsite, or streamline the Direct Data Interchange process with their partners. All customers will have to do is copy their data to a device, such as an external hard drive, create a manifest file with authentication information and a digital signature, e-mail loading instructions and ship the device. AWS lays out guidelines for the storage devices on an information page at its Web site.

When it arrives, the device will go to an AWS Import/Export station and the data will be loaded onto the customer's S3 data bucket, generally the next business day. Customers will pay US$80 per device handled and $2.49 per hour for the labor involved in loading the data, plus the standard charges for storing that data on S3. The service is available now in beta testing, for importing only, but will be expanded to include exporting in the coming months, Amazon said.

With many enterprise Internet connections, Import/Export will often be faster than online uploads or downloads, according to Amazon. For example, on a T-1 leased line (1.5Mb per second), with 80 percent of that line devoted to the transfer, it would take 82 days to send 1TB of data, Amazon said. As a general rule, S3 customers with only a T-1 should think about using Import/Export for sending 100GB or more of data, the company said.

Even a faster T-3 leased line (just under 45Mb per second) would take three days to send 1TB, so shipping would be a good option for anything above 2TB, Amazon said. A Gigabit Ethernet Internet connection could send 1TB in less than a day, Amazon said. But even if an enterprise is using a metro Ethernet link like that, it's unlikely to have that amount of capacity all the way to Amazon, 451's Baltazar pointed out.

"If you really have to have that data up there fast, it does make sense," Baltazar said. The method isn't new: For example, when banks set up new branches and want to have large amounts of information available on site, they typically ship drives because they don't have days to wait for a transfer. Online backup and disaster-recovery vendors also offer this approach. It's developed in just the past few years as the growth in data, driven by multimedia, has outpaced the acceleration of Internet connections, he said.

What's new is that Amazon, a cloud storage provider that offers more than just backup, is using the technique. The core business model for AWS is providing storage on S3 for applications that run on Amazon's EC2 cloud computing infrastructure.

Amazon Buys Maker Of iPhone E-Book Reader

Software like Lexcycle's Stanza and Amazon's Kindle iPhone application could drive adoption of electronic books and magazines further by making them available on more than just the Kindle.
##CONTINUE##
Amazon.com on Monday said it bought Lexcycle, maker of the Stanza electronic book reader for the iPhone and the iPod Touch.

The announcement comes almost two months after Amazon introduced a version of the software that powers the retailer's Kindle e-book reader for the same two Apple gadgets. Lexcycle disclosed the acquisition in a short company blog. Financial details were not disclosed.

Software like Lexcycle's Stanza and Amazon's own Kindle iPhone application could drive adoption of electronic books and magazines further by making them available on the millions of devices that Apple has sold to date. While the iPhone and iPod Touch only have 3.5-inch diagonal screens, the display is considered large enough and of sufficient quality to be acceptable for reading.

Stanza is a free application that has had more 1 million downloads and provides access to a variety of online e-books stores, including Barnes $ Noble's and some free sources that offer public domain or free content. Lexcycle also offers a desktop version of its software, which allows users to convert Microsoft (NSDQ: MSFT) Word and Adobe (NSDQ: ADBE) Acrobat file formats for reading on the iPhone and iPod Touch.

The acquisition, along with the release of its own iPhone/iPod app, shows that Amazon is more interested in promoting and selling e-books than in dominating the reader device market, Ezra Gottheil, analyst for Technology Business Research, said in an e-mailed commentary. Amazon is eager to drive the growth of e-books, which are far more profitable than traditional books. That's because warehousing and distribution costs are so low.

"TBR believes Amazon will remove direct access to paid e-book distributors, encouraging them to use Amazon for distribution to Stanza," Gottheil said. "The company will likely maintain access to free content, and may even provide distribution facilities, in order to drive e-book growth."

Buying Lexcycle also shows that Amazon believes Apple will eventually sell an iPhone-compatible device with a larger screen that will become popular as an e-book platform, Gottheil said.

"This acquisition is another sign of the increasing importance of e-books, as they supplant most printed books," Gottheil said. "TBR believes e-books will come to dominate the publishing of most types of books, fiction and nonfiction."

Amazon is credited with jump-starting the e-book business with the Kindle, which experts say has been growing in popularity among travelers looking for an alternative to the books and magazines they take on a long flight. While Amazon has not released sales numbers for the Kindle, industry watchers believe the $359 device is too expensive for the mainstream market. Nevertheless, the Kindle is popular enough to account for 10% of the sales of the 230,000 books Amazon sells in electronic format and physical form, according to the retailer.

Amazon.com Eyes CIOs With Its AWS Cloud IT Services

Although skeptics raised eyebrows over Amazon.com's decision to provide hosted IT infrastructure services, the e-commerce giant remains firmly committed to this business, as it increasingly courts CIOs and IT managers.
##CONTINUE##
Amazon.com officially entered this market in March 2006 when it launched its Simple Storage Service (S3) and the Amazon Web Services (AWS) subsidiary, which today provides a suite of Internet-based IT infrastructure services.

"We're trying to provide an end-to-end suite of services that together form a platform for outsourced IT infrastructure," said Adam Selipsky, vice president of product management and developer relations for AWS. "We want our customers to be able to run their IT infrastructure in our cloud. Whatever that means to them is what it will end up meaning to us."

So far, AWS services have been mostly targeted at and consequently embraced by startup companies and small development teams seeking inexpensive and flexible computing resources for Web applications. However, AWS has its sights set on large companies and their key technology decision makers: CIOs, CTOs and IT managers.

"Realistically, today AWS is more targeted at startups, but its ambition is to target the enterprise," said Lydia Leong, a Gartner analyst.

While enterprises are the smallest customer segment currently for AWS, it holds the potential for generating the most revenue, said James Staten, a Forrester analyst.

Selipsky said that AWS has had Fortune 500 customers from the beginning, but acknowledges that segment hasn't been its core audience.

"It's fair to say early on the majority of our usage was driven by startups and smaller companies. That's not terribly surprising. This is a different way to think about computing and application development," he said. "Small companies typically are more risk tolerant and they have fewer legacy apps to deal with."

However, interest from large companies is rising. "One surprise has been how quick enterprise interest has picked up," Selipsky said.

A reason behind this is probably the rising popularity and increasing acceptance of cloud computing in the past year, both for hosted infrastructure services like the ones AWS offers and for SaaS (software-as-a-service) products like Google's Apps communication and collaboration suite and Salesforce.com's business software.

"Amazon has clearly already begun to dominate the conversation, which is important. But at the same time, it's still at the beginning of offering something as opposed to done with offering something as it were," Leong said.

AWS also offers Elastic Compute Cloud (EC2) for computing resources, SimpleDB for database needs, Simple Queue Service (SQS) for passing data among distributed systems, the CloudFront content delivery service and Elastic MapReduce, which automates the use of Hadoop clusters for processing large data sets.

AWS has a few glaring gaps in its menu, though. "The biggest shortcoming is a third-party audit of their internal procedures, which would give enterprises comfort with how AWS protects the data and ensure availability," Staten said.

Another thing that AWS could improve is simplifying the way in which customers monitor their AWS hosted instances. "Amazon hasn't made that very easy," he said.

In addition, load-balancing capacity for applications remains a very manual process and AWS could automate this process more, said Staten, who expects AWS to address these three areas in the near future.

The list of potential new services and features that AWS could add is very long, Leong said. "They're at the very beginning of the curve. There are a zillion things that the customers want that they can't yet have," she said.

Software consultant Matt Passell, founder of Grove Hill Software near Boston, has been testing and evaluating AWS services like S3 and EC2 for potential recommendation to his clients since early last year.

"It's been a good experience. It's been great at the rate with which they have come out with new stuff and their response to developer requests," Passell said.

"Amazon didn't just set this up and sat on it. It's very clear they're being very active about enhancing AWS," he added.

Although AWS services may not be a good fit for all customer projects, they hit the sweet spot in a number of cases, such as when a company plans to launch a new Web site or online service, he said.

In that case, AWS may offer more flexibility for scalability needs and lower cost than setting up one's own servers on premise or in a collocation facility, Passell said.

Analysts praise AWS for offering services that are comparatively low in price and billed on a usage basis, without upfront or minimum fees.

"They have introduced a new business model and as a result everyone is chasing them. They've jumped to the forefront of the hosting business as a result," Staten said.

AWS competitors include GoGrid Cloud Hosting, Rackspace's Mosso, Joyent and Layered Technologies' Grid Layer, along with dozens of other players.

AWS also gets good marks for the uptime and reliability of its hosted systems.

"At this point it's pretty solid and stable," Staten said. "They've had a few outages here and there and some latency issues, but nothing that an enterprise wouldn't have experienced itself with its own on-premise systems."

Since Amazon's main business continues to be online retailing, the question about its long-term commitment to AWS is a valid one for CIOs to ask, but less so than three years ago.

"Amazon will tell you that they're very committed to making this business work," Leong said. "Yes, this is a drop in the bucket compared to Amazon's retail business, but it's a business they want to be in."

Selipsky said AWS gets this question less and less, since it now has an established track record as a provider of hosted infrastructure services. More than 490,000 developers have registered with AWS, a number growing between 30,000 and 50,000 per quarter. S3 has now over 52 billion files stored in it, up from 40 billion a quarter ago, he said.

"Internally we're committed to this business at the very highest levels of the company. We believe this can become a financially meaningful business for Amazon," Selipsky said, while declining to give revenue or profit details about AWS.

In the controversial issue of data and application lock-in in cloud-computing services, both Staten and Leong said AWS is better than most. "Amazon is pretty clean in this regard. Their API is completely open," Staten said.

"AWS doesn't have much in the way of lock-in at all right now," Leong said.

However, Staten warns that there is a degree of lock-in with SimpleDB, due to a specific database structure, as well as SQS and CloudFront.

Selipsky said AWS is committed to openness and interoperability, because it sees customer choice as key to its success. Regarding discussions about cloud computing industry standards, he said AWS believes they're needed. "The discovery of which areas require standards will occur over time and we look forward to being active participants in that discussion," he said.

With this market getting more and more crowded every day, the key for differentiating oneself is to stay in close contact with customers, Selipsky said.

"The first thing is to continuously innovate. We have a strong track record of releasing new features and new services. The other thing is to solve real problems for customers. All the features we've released after initial versions of our services have been in response to lots of in-depth customer conversations and requests for us to tackle additional issues," he said.

"As long as we're being innovative and helping customers with their problems, we should be adding a lot of value and shouldn't have any problem standing out," he added.

Microsoft, Amazon.com Show ‘Big Negative Surprises’ May Be Over

Microsoft Corp. and Amazon.com Inc. climbed in extended trading yesterday after reporting earnings that reassured investors, capping a week of reports by technology companies that showed the worst may be over.
##CONTINUE##
Microsoft, the world’s largest software maker, rose as much as 5.9 percent after predicting that it can shave an extra $700 million from operating expenses this year. Amazon.com’s sales increased 18 percent as more customers took advantage of free- shipping promotions.

“A lot of the big negative surprises are behind us,” said David Rudow, an analyst with Thrivent Asset Management in Minneapolis. The company oversees about $65 billion, including Microsoft shares. “We’ve seen the worst. It’s just a question of when we see return to growth and normal spending again.”

The Standard & Poor’s 500 Information Technology Index has advanced 13 percent this year, compared with a 5.7 percent loss for the S&P 500 Index. Apple Inc., EBay Inc. and AT&T Inc. reported earnings this week that topped analysts’ estimates, a sign that spending on everything from iPhones to e-commerce held up in the worst recession since World War II.

Microsoft, based in Redmond, Washington, rose as high as $20.03 in extended trading yesterday. Seattle-based Amazon.com, whose shares have doubled since December, advanced as much as 3.2 percent to $83.20.

Travel Reductions

At Microsoft, cost savings helped overcome the first revenue decline since the company went public in 1986. Sales fell 5.6 percent to $13.6 billion in the third quarter, which ended March 31. Profit declined 32 percent to $2.98 billion. Excluding some costs, earnings were 39 cents, matching the estimate of analysts in a Bloomberg survey.

Job cuts, travel reductions, marketing cutbacks and a slower expansion of Microsoft’s campus helped Chief Executive Officer Steve Ballmer save more money than expected. For the year ending in June, Microsoft forecast expenses of as little as $26.7 billion, compared with a previous estimate of $27.4 billion.

“Microsoft hasn’t really had to show all that much expense control during its entire lifetime as a company, so it’s good to see that when things turn bad, they can bring down their costs accordingly,” said Kimberly Caughey, senior equity analyst at Pittsburgh’s Fort Pitt Capital Group Inc., which owns the shares.

Microsoft reaffirmed plans to eliminate as many as 5,000 jobs by the middle of 2010, with the goal of saving $1.5 billion annually in operating expenses.

‘Actually Pleased’

“While I can’t say I’m happy with any quarter where our revenue and earnings per share decrease, I was actually pleased with our relative performance,” Microsoft Chief Financial Officer Chris Liddell said on a conference call with analysts yesterday.

At Amazon.com, the world’s biggest Internet retailer, profit jumped 24 percent to $177 million, or 41 cents a share, topping analysts estimates. Sales rose 18 percent to $4.89 billion.

Amazon.com was able to improve profitability by saving money on shipping and doing a better job managing inventory, Chief Financial Officer Tom Szkutak said on a conference call. Gross margin, or gross profit as a percentage of sales, expanded to 23.5 percent from 23.1 percent a year earlier.

Rival EBay reported sales and profit this week that also beat estimates. CEO John Donahoe said consumer spending showed signs of strengthening in the second half of the quarter.

IBM, EMC

While there may be signs of improvement, not all technology companies are skirting the recession. International Business Machines Corp., the world’s biggest seller of technology services, reported first-quarter revenue this week that missed analysts’ estimates after demand for services and computer hardware shrank. EMC Corp., the world’s biggest maker of storage computers, posted a 20 percent drop in first-quarter profit yesterday because companies curbed spending on its machines.

VMware Inc., the biggest maker of programs that let servers run multiple operating systems at once, predicted this week that sales may fall for the first time in its history.

Goldman Sachs Group Inc. estimates that global technology spending will fall 9 percent this year. Purchases in developed economies, including the U.S. and Europe, will drop 12 percent.

Still, technology companies have fared better than other businesses this year because they aren’t as dependent on short- term financing, said Michael Cuggino, chief executive officer of San Francisco-based Pacific Heights Asset Management LLC.

“Overall technology held up pretty well,” he said. “I expect to see it continue.”

亚马逊拿云术:闲置资源变利润奶牛

悠闲地坐在星巴克,打开刚买的上网本,网游程序员小王(化名)很快就开始了对游戏的测试,此时除了操作系统,小王的电脑里空空如也,但他依然能调取所需要的核心数据——他的游戏开发小组刚刚租用了云计算。
##CONTINUE##
“中国有越来越多的软件开发者开始接受这种新模式。也许不久后提到亚马逊,人们的第一反应不再是在网络上买书,而是它的云计算。”4月7日,来中国考察市场环境的亚马逊(NASDAQ:AMAZON)云计算解决方案和网络服务部(AWS)高级经理Jeff Barr告诉记者,到目前为止,对于亚马逊云计算的登录量已经超过它的零售相关页面的点击量,目前有520亿个对象在亚马逊云计算系统里面进行着数据交换。

这无疑是个天文数字,亚马逊也凭此成为全球云计算的巨头。这样庞大的一个业务却始自于一次无心插柳。

6年前,互联网从崩盘的科技泡沫中开始逐渐复苏,作为全球最大的图书在线零售商,劫后余生的亚马逊也开始不断地感受到点击量的节节上升。为了能满足越来越多的来自全球的访问者,亚马逊按照很高的一个峰值能力配置了自己的IT资源,因为对在线零售公司而言,在圣诞新年时,订单量和订单处理量是最大的,由于不能临时租用如此大量的设备,亚马逊必须对其进行长期构建。不过,在平常非峰值的时候,这些运算能力就处于空闲状态,大大浪费了资源。亚马逊接下来发现,可以把这些空闲的资源打包卖给自己的不少客户,这便形成了云计算的雏形。

“科技类公司对于IT资源需求的规模随时在变,有时业务扩展得非常快,但在经济不景气的情况下,只需要很少的配置。可是IT资产是贬值最快的资产,如果花了很多钱在IT构建上,就很难保证资金不被浪费,此时用云计算则可以随时满足不同的需求。”Jeff Barr说。

企业是平的?
作为一种新兴的商业计算模型,云计算的核心特点就是可以将计算任务分布在由大量计算机和运算能力构成的资源池上,使各种应用系统根据需要获取计算力、存储空间和各种软件应用。

2007年,一个名为DROPBOX的在线文件分享同步网站悄然成立,它的创始人是两个再普通不过的个人站长。不过不久后,这个不起眼并且背后也并没有大公司支持的网站却获得了来自风险投资商红杉和Y Combinator的入股。与它类似的是个叫做SMUGBUG的专业高清摄影照片分享网站,它从小到大默默地成长,如今其存储地空间令人咋舌地超过1000TB。

“这两家网站都使用了亚马逊的云服务,因此不必投入巨资去购买昂贵的IT设备,这使得个人开发者有机会做大。”Jeff Barr说。

弗里德曼“世界是平的”的理论揭示出,互联网的普及使得东西方的人们得以在同一地平线上起跑,填补了知识和信息鸿沟。以此类比,云计算则使得企业间的竞争有机会在更为平等的基础上进行,因为对科技企业而言,耗费资金最多的IT设备采购的高门槛被渐渐削平,创业者将更多地直接比拼智力和创意,而不是服务器和软件的多少,“企业也成了平的”。

Jeff Barr表示,亚马逊的云计算允许开发者根据需要选择不同的服务,或者把他的服务进行不同的组合,也可以面向编程语言或操作系统都支持的多种平台,“这种开放使得开发者有了多样性和灵活性。”

目前亚马逊最核心的一个产品便叫做弹性云(EC2),用户在云端发出一个指令,这个云就会分析出指令后,在几分钟之内,同时调用亚马逊全球的从一个到几千个服务器服务。此外,亚马逊也提供简单存储和备份服务,以及简单数据库服务。弹性云主要基于时间收费,比如以1毛到8毛美金每小时租用;后两者按照字节收费,或按照每个月的使用字节收费。

在“企业是平的”面前,除了个人开发者得以施展拳脚,一些像小王所在网游公司那样的中小型企业也可以靠此节约成本,事实上,亚马逊目前在美国已经开始为大型政府机构、企业高校、研究机构和分析单位在提供服务。

中国云攻略
目前,亚马逊已经计划把云计算的触角伸向了中国,尽管此次来华,Jeff Barr对自己的具体收获避而不谈。

“我们目前还没有一个准确的时间表,但会一直对中国市场保持关注,这也是为什么我们要来中国跟开发者面对面沟通。主要是来了解他们的兴趣和需求,以及使用服务中间可能会遇到哪些问题。“Jeff Barr透露,目前中国开发者使用亚马逊云计算主要是为了服务它们在美国、欧洲的客户。

实际上,在亚马逊进入中国市场的门槛中,客户的需求固然重要,但目前政策的不明朗是其最大障碍。由于在华运营云计算,需要在本地设置大量的服务器以及带宽资源,这对于云计算运营商尤其是亚马逊这样的以提供底层IT基础架构为主的公司,将面临当地的相关通讯政策限制。其他家云计算厂商的相关人士也向记者表示了这样的看法。

据悉,亚马逊目前在全球14个地区设立了相关的服务器,其中离中国大陆市场最近的架设在香港。“至于何时进入,我们需要遵循相应的政策和法规。”Jeff Barr说。

此外,经过在美国跟谷歌、IBM等云计算巨头激烈竞争,亚马逊入华后在定价上或许将仍沿用在美的价格战模式。Jeff Barr称,云计算的定价是在成本之上设置一个合理的利润空间,然后尽量把价格压到最低,“比如有时其实我们打九五折就可以了,但仍会尽量把它打到八折。这也是亚马逊在图书零售中的理念。”

“孤云”散落难成群
“天上浮云似白衣,斯须改变如苍狗”。就在全球各大云计算巨头纷纷建云之际,如何将飘散在各处的一片片的零散云集合起来,防止白衣苍狗般的变幻,成了用户最关心的问题——正如互联网,只有在全球使用统一的标准后,信息才能无界地自由流通。

然而,现实却颇具讽刺。3月31日,由IBM发起的主张云计算开放和互用的《云计算宣言》出师不利,尽管包括AMD、EMC、Sun、SAP、VMWare等芯片、存储、虚拟化、软件等大厂商先后签署宣言,然而微软、亚马逊、Salesforce、谷歌等巨头却对此嗤之以鼻,拒绝加入,并对此宣言的部分内容提出了质疑。在这场纷扰的标准之争背后是利益和客户的争夺。

目前,对于正在崛起的云计算市场,上述几家巨头都在积极布局,且获益匪浅。尽管谷歌、微软并没有透露自己云计算营收。不过据悉,Salesforce在云计算的收入已超过10亿美元,亚马逊去年在云计算上的收入则已经突破1亿美元,对去年纯利润为6.5亿美元的亚马逊而言,这个无心插柳出来的业务贡献已很可观。

“我们从来没有正式确认过这样的数字。”Jeff Barr对此微笑回应,我不能透露具体数字,不过亚马逊云计算的增长速度很快,“去年底我到中国时平台上有49.5万开发人员,今天这个数字是54万。”手握54万的云计算开发人员,再加上9000万B2C零售用户的资源,亚马逊选择做一片“孤云”似乎很有底气。

对于Salesforce 10亿美元的领先收入相比,Jeff Barr表示,对方更多的是在应用层面的云计算服务,而亚马逊更多是底层的基础构架云计算;此外Salesforce经营云计算已有十年时间,而亚马逊的产品只有3年时间,还处在早期阶段;市场上有真伪云计算的概念,现在不少厂商不管干的是什么,都给自己贴上云计算的标签,“对此还是要仔细地去审视一下。”

事实上,亚马逊、谷歌、Salesforce、微软不会坐视由IBM牵头搞联盟时,也竞逐成为标准主导者。目前,不同云计算巨头提供不同的接入口和底层架构等标准, 这给客户直接带来应用困扰。对此,Jeff Barr表示,“我们并不排斥云的统一,但关键是要由用户决定并有可行性,这不是一个拍脑袋就能做的决定。”

Internal cloud's big test: Amazon vs. Cloudera

The debate about the validity of internal cloud implementations has raged on for some time now, with some claiming that cloud computing and wholly owned infrastructure don't mix, and others pointing out that applying "on demand," "at scale," and "multitennant" to enterprise IT data centers offers unique advantages to those who have already made that investment. It has been difficult, however, to do an objective comparison of the two approaches--until now.
##CONTINUE##
The announcement on Thursday of Amazon's new Hadoop-based Elastic MapReduce service, combined with the introduction of a commercial Hadoop distribution from start-up Cloudera, means that we finally have a reasonable means of watching which directions enterprise IT prefers. Let me explain.

Amazon's service is a simplified, prepackaged Hadoop implementation that can be leveraged by anyone with an Amazon account. The Amazon Web Services blog describes it as follows:

Today we are rolling out Amazon Elastic MapReduce. Using Elastic MapReduce, you can create, run, monitor, and control Hadoop jobs with point-and-click ease.

You don't have to go out and buys scads of hardware. You don't have to rack it, network it, or administer it. You don't have to worry about running out of resources or sharing them with other members of your organization. You don't have to monitor it, tune it, or spend time upgrading the system or application software on it.

You can run world-scale jobs anytime you would like, while remaining focused on your results. Note that I said jobs (plural), not job. Subject to the number of EC2 (Elastic Compute Cloud) instances you are allowed to run, you can start up any number of MapReduce jobs in parallel. You can always request an additional allocation of EC2 instances here.

Processing in Elastic MapReduce is centered around the concept of a Job Flow. Each Job Flow can contain one or more steps. Each step inhales a bunch of data from Amazon S3, distributes it to a specified number of EC2 instances running Hadoop (spinning up the instances if necessary), does all of the work, and then writes the results back to S3.

Each step must reference application-specific "mapper" and/or "reducer" code (Java JARs or scripting code for use via the Streaming model). We've also included the Aggregate Package with built-in support for a number of common operations such as Sum, Min, Max, Histogram, and Count. You can get a lot done before you even start to write code!

Cloudera, on the other hand, provides a Hadoop build that you can deploy wherever you wish:

Cloudera's Distribution for Hadoop is based on the most recent stable version of Apache Hadoop. It includes some useful patches back-ported from future releases, as well as improvements we have developed for our support customers.

Cloudera's Distribution includes everything you need to configure and deploy Hadoop using standard Linux system administration tools.

Here's what I'm thinking: enterprise IT is looking at an entirely new class of applications that take advantage of MapReduce to process very large sets of both structured and unstructured data for things like predictive analysis, sorting/sequencing, and data mining. Both commercial Hadoop offerings meet the demand for a platform to simplify the development and operation of these applications. The primary difference is the where, not so much the what.

That is exactly what will make the competition between the two offerings so compelling to watch. Let me break it down for you:

  1. Will the requirement to own and operate hardware work against Cloudera? What makes the Amazon offering so groundbreaking (and it will prove to be historic, in my opinion) is that it is now possible for anyone with a need to analyze large data sets to do so simply for the cost of data storage plus processing time. (Note that the use of Elastic MapReduce adds a nominal cost to the server instances that host the instances.)

    Where "grid computing" was once the playground of large enterprises and academic institutions that could afford the hardware to justify the cost of building them out, Amazon makes it possible for even individuals to run such jobs for a few tens or hundreds of dollars.

    Cloudera, on the other hand, requires that the hardware be available to install it on. That either means existing server capacity, new hardware (which greatly adds to the cost, and can only be justified for continuous Hadoop use), or leased capacity. The latter starts to look a lot like Amazon's service.

  2. Will Amazon's requirements to use S3 work against it? There are three reasons why I see it might:

    • The commonly cited concern about data security outside of corporate firewalls. (Even if the perception is wrong, the perception exists.)
    • The cost of data transfer to and from the S3 service--currently as high as 17 cents per gigabyte a month.
    • The cost of storage of both the raw data and the aggregate results--currently as high as 15 cents per gigabyte a month.

    It should be rightly noted that if you already rely on S3 to store your data sets to be processed, this is a great deal. However, if you have to upload terabytes or even petabytes of data to be combed through by MapReduce, then this could get quite pricey on its own, and existing infrastructure might serve the purpose well. If you are going to leave the data up there permanently--and update it regularly--the cost of Amazon's service should be weighed against the cost of owning and operating that storage yourself in your existing facilities.

  3. Will the so-called "barrier of exit" stand up? I'm not even arguing that the choice will be based solely on the comparative costs to the business. In fact, what I am interested in is the extent to which business units and departments will simply bypass IT altogether to build and run their own jobs in Amazon Elastic MapReduce.

    If IT maintains a valuable service using existing facilities and computing investments, then Cloudera will likely do fine. If not, then Amazon stands to be the overwhelmingly dominant commercial Hadoop implementation.

I should also note that running a Hadoop instance is not the same thing as cloud computing in and of itself. An internal Cloudera implementation is not necessarily an internal cloud, though if operated "on demand," "at scale," and with multitenancy, it certainly qualifies as a cloud.

I will be watching this space closely for the next year or two. I have a feeling that Amazon will do fine, regardless, as there are many possible implementations that would benefit from a completely public cloud implementation. The real test is probably how much opportunity Cloudera finds within enterprise data centers.

Cloudera also has much more competition from the free downloads of Hadoop than Amazon has, in my opinion, as it faces a more traditional open-source competitive landscape.

Is your company looking at MapReduce for a new generation of data-mining applications? If so, what will you choose: the public, external cloud implementation of Hadoop from Amazon Web Services, or the wholly owned, internal implementation of the same from Cloudera?

Amazon Makes Java Deployment Easier On EC2

Less than a month after enabling developers to launch Windows and SQL Server instances in the Europe, cloud infrastructure provider Amazon Web Services (aws.amazon.com) has introduced the AWS Toolkit for Eclipse (www.eclipse.org), a plug-in for the Eclipse Java IDE that makes it easier for Amazon EC2 developers to develop, deploy, and debug Java applications on Amazon's infrastructure.
##CONTINUE##
According to Amazon's announcement this week, the AWS Toolkit for Eclipse lets developers get started faster and be more productive, as well as providing basic management features and tools for deploying and debugging Java web applications.

Eclipse is an open-source, multi-language software development platform, comprising an IDE and a plug-in system to extend it. It is used to develop applications in Java, as well as other languages such as C/C++, Cobol, Python, Perl and PHP by means of plug-ins.

The Eclipse open source community began in November 2001 as project to build an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software.

Based on the Eclipse Web Tools Platform, the AWS Toolkit for Eclipse guides Java developers through common workflows and automates tool configuration, such as setting up remote debugger connections and managing Tomcat containers. Prior to this release, developers needed specific knowledge of several systems and manual processes to get Java web applications running in scalable configurations on Amazon EC2. The steps to configure Tomcat servers, run applications on Amazon EC2, and debug the software remotely are now done seamlessly through the Eclipse IDE.

Amazon Web Services developer evangelist Jeff Barr noted on the company blog that for the past few years, Amazon has been simplifying the process of acquiring, customizing, and running server instances on demand.

"We want to make the process of building, testing, and deploying applications on Amazon EC2 as simple and efficient as possible," Barr wrote. "Modern web applications typically run in clustered environments comprised of one or most servers. Unfortunately, setting up a cluster can involve locating, connecting, configuring and maintaining a significant amount of hardware. Once this has been done, keeping the operating system, middleware, and application code current and consistent across each server can add inefficiency and tedium to the development process."

In keeping with the spirit of the Eclipse project, the Eclipse AWS Toolkit is available at no additional cost for Amazon EC2 developers and Amazon encourages users to contribute code to the project.

Amazon stresses cloud opportunities for developers

EclipseCon event also features introduction of a plugin linking Amazon's cloud with Eclipse's platform
##CONTINUE##
Cloud computing and opportunities it presents for application developers were stressed Wednesday by Amazon and a user of its cloud service during a presentation at the EclipseCon 2009 conference.

Amazon at the Santa Clara, Calif. conference also revealed software enabling development of cloud applications via the Eclipse platform.

With cloud computing, software providers need not worry about infrastructure issues, such as varying need for compute cycles and storage, said Peter Vosshall, vice president and distinguished engineer at Amazon. "We take care of that for you," Vosshall said.

The AWS (Amazon Web Services) platform features services such as Amazon's EC2 (Elastic Compute Cloud) for developers to build and deploy cloud applications and S3 (Simple Storage Service) for Internet-based storage.

AWS features a pay-as-you-go model, said Vosshall. "You pay for what you're using rather than having a whole datacenter full of servers," and paying for unused capacity, he said. Capabilities like bandwidth management, server hosting, financing, and negotiating long-term contracts become much simpler via cloud services, Vosshall stressed.

"At the end of the day, developers, whether you're in a startup or working in a big enterprise, you want to deliver stuff," Vosshall said.

By resorting to supplying their own infrastructure, developers either can overestimate what they need or, even worse, underestimate, he said.

An official with AWS user SmugMug, an online video and photo-sharing site, cited successes with Amazon services. SmugMug processes more than 40 terapixels a day and has peaks at times, such as Christmas, which must be accommodated, said Don MacAskill, CEO at SmugMug.

"We need to scale up and down a lot," MacAskill said. SmugMug even enjoys such benefits as not having to depreciate and amortize hardware purchases, he said. Updating software is easy, he added. The only issue MacAskill raised pertaining to AWS was it takes a minute or two to add instances.

"We're huge fans of Amazon Web Services and wouldn't be able to build our business the way we have without it," MacAskill said.

An attendee at EclipseCon saw cloud computing as a boon for startups. "This definitely opens up all kinds of opportunities for small startups," said Mike Coon, senior technical staff member at consulting firm Proteus Technologies. "You don't have to worry about your infrastructure in your datacenter going down."

Developers at large enterprises also could benefit, he said. "I think it’s a great opportunity to prototype some ideas without having to interact with your own IT center and try to get dedicated resources for something you're trying to build," Coon said.

S3 and EC2 were launched in 2006 and have had a steep growth curve, Vosshall said. S3, for example, stored 800 million objects in 2006 and now stores 40 billion objects.

"At one point, we were spending more bandwidth to serve AWS customers than retail customers," he said.

Amazon also announced at the event the release of the initial version of AWS Toolkit for Eclipse, a plugin for Eclipse targeted for Java developers. "The goal of the toolkit is to make it easier to build applications in the cloud on the AWS platform," said Jason Fulghum, software development engineer at Amazon.

The toolkit leverages both the core Eclipse IDE and the Eclipse Web Tools Platform.

Memo to Google & Amazon: ‘Cloud Computing’ Really Is Time-Sharing. Next: Will Punch Cards Make A Comeback?

SAS, the North Carolina supplier of business analytics software, last week got a lot of attention from its announcement that it was spending $70 million to construct a “cloud computing’ facility.
##CONTINUE##
Chief executive Jim Goodnight, one this nation’s billionaire software magnates, though, was having a bit of a chuckle Monday at his company’s annual executive and user conference, its Global Forum.

Seems he just regards “cloud computing” as a marketing hook. And that there’s nothing really new about drawing on computing power in “the cloud,” where you can’t see where it’s coming from.

In fact, the marketing mavens at SAS originally wrote up the release about the new facility in Cary, N.C., as a building with a lot of servers inside.

“It’s really a server farm. They wrote it up as a “server farm,’ ‘’ Goodnight said Monday at the forum. “ I said, Eh, no let’s not use that. That’s old-fashioned. Use “cloud computing.”

That led to national and international coverage of what amounts to a fairly small capital expenditure for a company that generates $2.6 billion a year in software revenue.

“Wow, my God, we came up with that and all the papers went crazy,’’ he said. “They’re calling it ‘cloud computing.’ The cloud is nothing more than a damn big server farm.’’

In effect, SAS is making fun of the use of terminology to solve an age-old problem: How to make use of excess capacity in your data infrastructure. If Amazon or Google wants to make hay with the term “cloud computing,’’ SAS will just pitch in with its fork, as well.

“Google, Amazon had these huge server farms that they had to have to store all the data and they got all these CPUs that aren’t that terribly busy. Why not try to sell them off? Sell some of the time,’’ he said.

“What we’re talking about here is a concept called time sharing. That’s all it is. We’ll sell you a piece of our hardware if you give us X number of dollars. In this case, it’s real cheap. But that’s all it is, time-sharing,’’ he said.

Their goal, he contends, is simply to sell the excess hardware they have got sitting around, without having a lot more people to service it. This is not “ anything hugely different’’ from how time-sharing began in the early days of corporate computing.

“It’s funny we’ve gotten to where everybody wants everything delivered on the Web. So we’re back to like (IBM) 3270 mainframe days,’’ he said. “All the interactivity we used to have on the desktop is being sacrificed to go back a very simple static screen like we had on the mainframe. It all comes around. I don’t know when we’ll see punched cards again, but you never know.”

Amazon's Kindle Secret is in the Software

By building a full-scale publishing platform rather than just a gadget, Amazon has managed to dominate the e-book market.
##CONTINUE##
E-Book Readers Can Do Better" that outlined what products like the Amazon Kindle and the Sony Reader series would need to add before they truly appealed to mainstream consumers. One year and one tremendous endorsement from Oprah later, Amazon's Kindle 2 incorporates a lot of my suggestions. Still, it isn't the latest Kindle that's cemented Amazon's leadership role in the e-book market. It was today's announcement of a free Kindle reader for the iPhone, because it shows that Amazon really understands what e-books are: software.

As a serious book lover, that's difficult for me to admit. My first edition copy of Ernest Hemingway's Winner Take Nothing is one of my most prized possessions. Seven Pillars of Wisdom, by T.E. Lawrence, complete with its fold-out maps of the Arabian Peninsula, is one of the best things I've read in my life. Carrying my entire book collection up to my fourth-floor walk-up apartment required a fair amount of sweat and even a few tears. Yet despite the vast potential energy of my hundreds of books, their contents would likely fit inside a single Kindle 2. It can, after all, hold 1,500 titles. Good or bad, this is the world we now live in. And Amazon gets it.

Amazon has been wildly successful in the e-book biz. Last year, Kindles literally sold out. But this hasn't kept the company from supplying Kindle for iPhone, a move that's guaranteed to cut into Kindle 2 sales. The thing is, it will also help Amazon sell a lot more e-book titles, and will go a long way toward making Kindle the de facto e-book publishing platform in the U.S. Amazon's not just selling razors, after all—they're also selling the blades.

The move also indicates that Apple has ceded the e-book market to Amazon. That is probably best, since the iTunes franchise is already stretched thin distributing songs, music videos, TV shows, movies, podcasts, and iPhone apps. "iTunes Store" has become a misnomer; it seems like a name change is overdue. Still, to see Kindle as merely an e-book platform is to miss the forest for the trees. Kindle doesn't just mean books. It is a secure content delivery platform that can be used by every blog, magazine, and newspaper on the Web.

Most of these companies already publish on the Web, but the Kindle platform offers several key advantages. The first, naturally, is DRM protection. Amazon says it is up to content providers to choose or refuse DRM, but so far almost all of the book publishers have chosen to lock up their books. Given what's happened with the music industry, can you blame them? I would love to see a more open format, like ePub, supported by the Kindle, but given Amazon's current success that won't likely happen anytime soon.

For newspapers, magazines, and blogs, the issue is less DRM than it is fulfillment and subscriber management. As many of you know, PCMag.com recently went 100 percent digital, ceasing to print a paper magazine to focus exclusively on the Web and Zinio digital edition. One of the reasons we partnered with Zinio was so we would have a company that could bill subscribers and manage their accounts. Not many people have managed to do that on the Web, but platforms like the Zinio and Kindle offer a way for readers to get service and for publishers to get paid.

Before I coronate Amazon as the king of cloud-based content distribution, I'll point out a few places where the company could run aground. One problem revolves around Amazon's dual role as hardware and software vendor. First of all, it could cling too tightly to its closed format. Open-minded publishers like Tim O'Reilly, founder and CEO of O'Reilly Media, have already balked at joining Amazon's single-source, single-file-format delivery system. As the market grows, so will the demand for alternatives. Even Apple supports multiple file formats on the iPod.

Hardware devices like the Kindle are also vulnerable on the price front. $359 is a tough sell in a miserable economy, especially when you can buy a netbook for around same price. A raft of more basic, less-expensive e-book readers are slated to hit the market this year. They won't likely be as easy to use as the Kindle 2 or feature its wireless content delivery, but they'll probably appeal to the cost-conscious consumer who wants to get into electronic books.

My advice for Amazon is to push the books over the devices—the blades over the razors. The Kindle's competitive advantage isn't in its e-ink display or plastic keyboard, but in the 230,000 titles available at the click of a button. Amazon has become a real software publisher in the truest sense of the phrase.

Amazon unveils Kindle Application for iPhone

You may not have the latest $359 Kindle electronic book reader from Amazon.com, but if you own an iPhone or iPod Touch, a new application will let you access the same content on your Apple device.
##CONTINUE##
In a bid to increase its slice of the e-book market, the Seattle-based online retailer plans to roll out a free program Wednesday that brings several of the Kindle's functions to the iPod and iPhone's smaller screen.

The program, which can be downloaded from Apple's online application store, lets iPhone and iPod Touch users read the same electronic books, magazines and newspapers that Kindle owners can buy on Amazon.com. As with the Kindle, the iPhone app lets users change the text size on the screen, and add bookmarks, notes and highlights.

The application does not connect to the Kindle store, however, so users must access the Web browser on their iPhone, iPod or computer to buy the content.

If you happen to have a Kindle and an iPhone, Amazon's program will handily sync the two so you can keep your place in the same book on both devices.

The Kindle program isn't the first e-book reader for the iPhone, but it marks the first time Kindle content is available on a cell phone — a move Amazon recently said it would be making, and something that rival Google Inc. is also doing.

It arrives a few weeks after Amazon unveiled the second-generation Kindle, which has the same price tag as its predecessor but is skinnier and includes updated features like more storage space for books and a longer battery life.

Amazon has been working on the application for several months, said Ian Freed, who is Amazon's vice president for the Kindle. Freed said the company sees the software as a way to introduce non-Kindle owners to the device, potentially turning them into Kindle buyers. (Amazon does not say how many Kindles it has sold.) It also gives Kindle owners an additional way to read their content while on the go, he said.

He added that the new application will show books in color that were developed that way. This is unlike the Kindle 2, which has a 6-inch screen that only shows content in shades of gray.

The application does not include the text-to-speech feature Amazon built into the latest Kindle, which can read books aloud, sparking concerns among authors worried it would undercut separate audiobook sales. Amazon said Friday it will let copyright holders turn off text-to-speech on any book.

Amazon Yields To Kindle Text-To-Speech Objections

At issue are the payment royalties for e-books vs. audio books, which are currently more valuable than e-book rights.

Amazon.com is giving individual copyright holders the option of turning off the text-to-speech capability within in the Kindle 2, the latest version of the online retailer's electronic-book reader.
##CONTINUE##
While insisting the feature is legal, Amazon said it would make the technical changes needed to let copyright holders on a title-by-title basis enable or disable the feature that reads the content to the user.

"We strongly believe many rights holders will be more comfortable with the text-to-speech feature if they are in the driver's seat," the company said in a statement released Friday.

In an opinion piece in The New York Times titled "The Kindle Swindle?" Authors Guild president Roy Blount Jr. objected last week that Amazon wasn't paying writers for the audible rights of their works. The retailer does pay royalties to authors and publishers each time a person downloads a book.

Blount said e-books are not popular among mainstream consumers, but audio books have grown to a billion-dollar market, and sales continue to rise. "They are more valuable than e-book rights," Blount said. "Income from audio books helps not inconsiderably to keep authors, and publishers, afloat."

Despite yielding to the guild's concerns, Amazon said it believed text-to-speech introduced new customers to the convenience of listening to books and would thereby grow the audio-books business. "Customers tell us that with Kindle, they read more, and buy more books," the company said. "We are passionate about bringing the benefits of modern technology to long-form reading."

The guild's position drew heat from the National Federation of the Blind, which said the guild's position would make it more difficult for blind people to access audio books. The Kindle is among the most popular consumer electronics on Amazon.

Blount said American copyright laws provide for free audio to the blind, and the guild supports technologies that expand the availability of audio books to the blind. The Kindle, however, is not a device built for the blind, he said.

Amazon released the latest version of its e-reader, called the Kindle 2, a week ago. The device is slimmer and includes more storage than the original version. The Sony (NYSE: SNE) Reader is a major competitor.

Canonical Aims Koala at Amazon Cloud

Last Friday Canonical founder Mark Shuttleworth dubbed the next turn of Ubuntu “Karmic Koala,” the future Ubuntu 9.10 due in October, and immediately pointed its server side to the cloud.
##CONTINUE##
“Ubuntu,” he said on a blog, “aims to keep free software at the forefront of cloud computing by embracing the APIs of Amazon EC2, and making it easy for anybody to setup their own cloud using entirely open tools. We’re currently in beta with official Ubuntu base AMIs [Amazon Machine Images] for use on Amazon EC2. During the Karmic cycle we want to make it easy to deploy applications into the cloud, with ready-to-run appliances or by quickly assembling a custom image. Ubuntu-vmbuilder makes it easy to create a custom AMI today, but a portfolio of standard image profiles will allow easier collaboration between people doing similar things on EC2.”

Besides prioritizing Amazon, Shuttleworth offered the University of California at Santa Barbara’s Xen-based Eucalyptus Project as an open source alternative.

“What if you want to build an EC2-style cloud of your own?” Shuttleworth asked. “Of all the trees in the wood, a Koala’s favorite leaf is eucalyptus. The Eucalyptus Project, from UCSB, enables you to create an EC2-style cloud in your own data center, on your own hardware. It’s no coincidence that Eucalyptus has just been uploaded to universe and will be part of Jaunty [Ubuntu 9.04 now in alpha] – during the Karmic cycle we expect to make those clouds dance, with dynamically growing and shrinking resource allocations depending on your needs. A savvy Koala knows that the best way to conserve energy is to go to sleep, and these days even servers can suspend and resume, so imagine if we could make it possible to build a cloud computing facility that drops its energy use virtually to zero by napping in the midday heat, and waking up when there’s work to be done. No need to drink at the energy fountain when there’s nothing going on. If we get all of this right, our Koala will help take the edge off the bear market.”

The Koala desktop is very focused on netbook compatibility, faster boot time and the promise of a new designer look.

亚马逊Kindle成功源自设计细节

亚马逊在第一代Kindle的基础上进行了完善,解决了第一代电子书阅读器的许多问题。
##CONTINUE##
笔者从多年的产品评测中总结出一条重要经验,那就是不管产品给人的第一印象如何,决定产品成功与否的因素却是设计细节。

按键的形状或者位置稍有不同,用户使用时的感觉可能就会有很大的差异。因此亚马逊的第二代Kindle看似仅在第一代产品上做了一些细微的变化,但是却能给人耳目一新的感觉。

亚马逊在2007年底推出了划时代的Kindle阅读器,开创了电子书阅读器市场。虽然它的硬件设计普普通通,但是亚马逊推出的配套网络购买和下载服务发挥出点石成金之效,Kindle顺理成章地大获成功。亚马逊完善了第二代Kindle的硬件设计和软件配置,加上领先的网络购书服务,Kindle2已经远远领先于唯一的竞争对手索尼Reader。

使用新款Kindle来阅读电子书与在笔记本电脑上阅读电子书的感觉完全不同。你可用随身携带,随时阅读,再也不用为如何握持而发愁。而第一代Kindle就没有这么方便。Kindle1的表面布满了按键,用户常常感觉无处下手,在阅读过程中也经常出现无意翻页、跳转到菜单或碰到其他按键而打断阅读的情况。

与第一代Kindle相比,Kindle2的按键缩小了很多,布局也更加合理。亚马逊重新设计了翻页键的位置,不会因用户无意碰到阅读器的边缘而翻页。第二代Kindle取消了第一代产品中的滚轮设计,换成了常见于手机中的、更为传统的五向导航控制按键。这些设计上的变化不但让Kindle整机变得更为简洁,而且厚度也减少了一半,从而确保给用户带来更为愉快的阅读体验。

至于第一代Kindle中表现不错的部分,亚马逊或选择了保留原设计,或选择了进一步完善。用户可用通过Sprint的无线宽带网络下载电子书籍、杂志和报纸,而且无需注册或另外付费。购物账单由用户在亚马逊开设的帐户支付,网络费用则包含在电子书籍的售价之中。这样做存在一个负面影响,即亚马逊选择的网络技术以及内容授权问题限制了Kindle在美国市场的进一步发展。亚马逊还重新设计了Kindle的键盘,用户们可以更方便地在Kindle网店搜索书目,在书中搜索特定文字,或添加注释或书签。

除了上述改变或完善之外,亚马逊在第二代Kindle上还进行了其他一些改进。第二代Kindle采用了基于EInk公司技术的显示屏,它所支持的灰度显示由4级提高到了16级。第二代Kindle的能耗也进一步降低,电池充电一次的续航时间延长到了数日。翻页速度也比以前更迅速,而且还增加了读文本功能。第二代Kindle可以储存1500本电子书,因此管理书库可能会比用户使用第一代Kindle时遇到的容量不足问题更加难办。

如果用户的一个亚马逊帐户下挂多个Kindle阅读器,那么每一个阅读器都能够显示下载的内容。亚马逊向用户承诺,今后用户还能将下载的Kindle电子书装到其他设备上阅读。

然而第二代Kindle仍存在许多不足之处,可完善的地方还有很多。

EInk的显示屏使用了反射光技术,它比电脑或手机显示屏使用的背光更为悦目。但是与第一代Kindle一样,第二代Kindle中的文字颜色仍是浅灰色的,没有换成白底黑字显示模式,因此用户在光线昏暗的环境下就很难看清显示的内容。

另外,虽然亚马逊网店中的书籍多达20多万本,但是笔者经常发现找不到想找的书籍。

最后,还有一个令人不满的问题是,用户看过的书籍是无法再出售或送给其他人的。不过即使到以后,这一点可能也不会发生变化。

Kindle的最佳市场或许是巨大的教科书市场。但是教科书的价格不能太贵,而且显示的字体必须较大。EInk正在进行这方面的努力,但是不太可能在短期内实现。

笔者仍然喜欢象过去那样阅读实体书籍,但是偶尔使用一下Kindle也不错,毕竟将一整座图书馆装入这样一部小巧的便携设备绝对是一件令人高兴的事。

Amazon Web Services As The Center Of The Software Industry

IBM is the latest software company to make its wares available as machine images on Amazon Web Services. Expect to see more enterprise-class software vendors do the same as a fast-and-easy way to move their software into the cloud.
##CONTINUE##
Just look at the rollout of commercial software on AWS over the past 10 months to see what direction the arrow is pointing. Last May, Sun Microsystems introduced its OpenSolaris operating system and MySQL database on Amazon's EC2. In June, Red Hat followed with its JBoss application server. In September, Oracle reached agreement to offer its 11g database, Fusion middleware, and Enterprise Manager on EC2. In October, Microsoft followed with Windows Server and SQL Server.

When I was at Amazon's Seattle headquarters in November, Adam Selipsky, Amazon's VP of product management and developer relations, made it clear that the strategy was to keep expanding the commercial software choices available to business customers on AWS. "Absolutely," he said. "There are other databases out there. There are a lot of ERP applications. It will be a constant evolution."

So when IBM disclosed that it would begin offering DB2, Informix, WebSphere, and Lotus Web Content Management as pay-by-the-hour Amazon Machine Images, I wasn't surprised. The list of software companies distributing products in Amazon's cloud is sure to keep growing.

Which brings me to a point that I've made before: As AWS becomes a distribution channel for the enterprise software industry, analysts and others (myself among them) are going to want to visibility into that business. IBM, Microsoft, Red Hat, Sun, and Oracle are all licensing software through Amazon, yet Amazon is mum on AWS revenue, growth, and other information that would help us understand how it's going. Pressure will grow on Amazon and its partners to be more forthcoming.

At a glance, Kindle 2 looks better than predecessor

Here's the really quick read on Amazon's new electronic reader: The $359 Kindle 2 ought to make it easier to curl up with a good e-book.
##CONTINUE##
Kindle 2, which starts shipping Feb. 24, certainly addresses speed and the other main problem I had with the first-generation Kindle, namely navigation.

The clumsy scroll wheel has been replaced by a five-way controller for moving the text around on the screen. Amazon says you'll especially appreciate this new controller while reading newspapers. We'll see.

The display is crisper. And pages appear to turn faster — 20% faster, Amazon says. Apparently, you'll no longer inadvertently flip pages as happens way too frequently with the buttons along the edges of the original Kindle. That always drove me nuts.

I also loathed the cheap cover on the first edition. Kindle 2 has a hinge to ensure that a cover won't slide off, though the latest generation doesn't even come with a cover. Amazon sells a $30 leather cover as an accessory. Others will be available from Cole Haan and Belkin.

With or without a cover, Kindle 2 is more attractive than its homely predecessor, though that's not saying much. At a svelte 0.36 inches, Kindle 2 is about half as thick as before and thinner than most smartphones.

The power charger is also smaller. What's more, you can charge the device using a micro USB cable. Amazon says the battery can last about two weeks off a single charge, a 25% improvement. Battery life on the first Kindle wasn't a major issue.

As before, you can shop for books directly from the wireless Kindle Store, using Amazon's Whispernet. It runs on Sprint's fast EV-DO network. I didn't get to download any books on the new device (I got to hold Kindle 2 only for a moment), but Amazon ensures it will work much the same, with books arriving in less than a minute.

With 2 gigabytes of internal memory, you can store more than 1,500 books. The original had 256 megabytes of internal storage (about 200 books). But the original also had an SD memory card slot. There's no such slot on Kindle 2.

I'm looking forward to trying out the new Whispersync wireless syncing feature. It lets you start reading on one Kindle and resume where you left off on another Kindle. Where it could get interesting is when Amazon will let you sync with a cellphone, something it says is in the works.

Kindle 2 also can read out loud, perhaps while you are cooking or riding in a car. Based on the small sample I heard, it's a good thing Amazon calls this an "experimental" feature. The voice is robotic and nowhere near the quality of a book recorded, say, on Amazon's own Audible service.

Of course, not all books have audio versions, and Kindle 2 can read aloud anything that is on the device, including your own documents. The page automatically turns when content is being read aloud, raising intriguing possibilities, perhaps, for children's books.

On first impression, Amazon appears to have made a good device better, if not dramatically so. But I'll reserve my verdict until I've had a chance to put a Kindle 2 to the test. By curling up with it.

据法新社3日报道,亚马逊的这家新网店现阶段提供的游戏主打休闲类游戏,有超过600种游戏可供消费者挑选,而且价格全部在10美元以下。

报道说,与普通游戏下载服务网店的“店规”不同,亚马逊的这家网店开张伊始即打出了允许消费者在正式购买之前可先行试玩半小时的营销牌,不过游戏必须在基于微软视窗操作系统的个人电脑上才能运行。
