亚马逊官方网站的信息显示，亚马逊网络服务为亚马逊的开发客户提供基于其自有的后端技术平台的通过互联网提供的基础架构服务，利用该技术平台，开发人员可以实现几乎所有类型的业务。亚马逊网络服务所提供服务的案例包括：亚马逊弹性计算云(Amazon EC2)、亚马逊简单存储服务(Amazon S3)、亚马逊简单数据库(Amazon SimpleDB)、亚马逊简单队列服务(Amazon Simple Queue Service)、亚马逊灵活支付服务(Amazon FPS)、以及亚马逊土耳其机器人(Amazon Mechanical Turk)等。
Amazon.com probably doesn’t get enough credit for powering the growth of web services and cloud computing. Besides running its own e-commerce site, Amazon’s web service business — which rents computer processing and storage to small companies — is the host for tons of smaller businesses that have chosen to outsource their web operations to the Amazon cloud.
And the latest analyst estimates suggest that Amazon Web Services has become a huge business, with revenues of $500 million in 2010, according to UBS Investment Research. And that success is due in no small part to the rapid rise of social games such as FarmVille on Facebook.
Jeff Barr, evangelist for web services at Amazon, told me in an interview at the Casual Connect show in Seattle this month that Amazon hosts six to eight of the top 10 games on Facebook at any given time. That includes top Zynga and EA Playfish games, meaning that hundreds of millions of players are playing games on Amazon’s servers, without even knowing it. Overall, Amazon has hundreds of thousands of customers in 190 countries for its web services. It also powers big operations such as Netflix, NASA, Autodesk, NASDAQ and the New York Times.
Amazon’s service means that any small developer can offload the task of hosting a web application to Amazon and concentrate just on creating the app itself. As an application grows in popularity, Amazon adds more server processing power and storage to handle the traffic. But the developer is assured that the app is secure, backed up, and kept private from other apps makers using the same Amazon computers. Amazon can help young companies grow to unheard of scale while still remaining relatively small in numbers of employees. That means these “lean startups” don’t have to raise as much venture capital and can even reach profitability without much funding.
On the flip side, it’s clear that there is room for improvement. In Zynga’s FarmVille game, there are occasional outages. Zynga’s FrontierVille shot to 20 million users in three weeks. Zynga’s use of the cloud enabled that to happen, but there were times when users couldn’t log into the game. It isn’t clear whose fault it is when that happens. Often, developers don’t properly anticipate the challenges of adding so many users at once. The developers, however, have considerable control over the quality of service and speed that the Amazon cloud delivers, Barr said.
Despite such hiccups, companies such as Zynga have been able to stay with providers such as Amazon, even with more than 200 million monthly active users, rather than building their own data centers as Facebook and Google are doing.
The challenges are many. Developers are relying on the open source MySQL database to scale their businesses to tens of millions of users, yet the developers don’t want to hire an army of system administrators. Those developers don’t want to worry about backing up gigabytes worth of data. Amazon has to pay considerable attention to security, both physical security for its data centers and online security as well, as hackers are always on the prowl.
Developers can start out with a single Amazon server and even put it online for just eight hours a day. As they expand, they can add more servers and add more powerful servers, automatically, without talking to Amazon. Once they reach a certain size, Amazon talks with them.
Advances in semiconductor technology deliver cheaper and faster computing devices every couple of years. That results in faster, lower-power, and cheaper server microprocessors, which in turns leads to more efficient servers.
That allows Amazon to offer cheaper and cheaper computing services to its partners. Amazon is also using a variety of virtualization technologies that allow it to add or subtract servers from any given application. In its last 18 months, Amazon Web Services has had around nine price cuts on servers, storage and bandwidth, Barr said. Amazon operatings in three major regions around the world to serve its Web Services customers, and the company has a lot of buying clout with server and other equipment vendors so that it can get volume discounts on hardware.
UBS analysts Brian Pitz and Brian Fitzgerald estimate that Amazon Web Services will grow from $500 million in revenue in 2010 to $750 million in 2011. By 2014, it will bring in about $2.5 billion in revenue. The total market for web services is expected to grow from $5 billion to $6 billion in 2010 to $15 billion to $20 billion in 2014. Amazon Web Services is still a small sliver of the overall $25 billion in Amazon revenues, but it’s a growing slice. UBS estimates that the value of the Amazon Web Services business is $3.4 billion to $3.8 billion. The profits are expected to be about $58.2 million in 2010 and $100.7 million in 2011. Amazon has to keep plowing the profits back into hardware.(source:tencent/venturebeat)
