Amazon Web Services (AWS), is a collection of cloud computing services, also called web services, that make up a cloud-computing platform offered by Amazon.com. These services operate from 12 geographical regions^[2] across the world. The most central and well-known of these services arguably include Amazon Elastic Compute Cloud, also known as "EC2", and Amazon Simple Storage Service, also known as "S3". Amazon markets AWS as a service to provide large computing capacity more quickly and more cheaply than a client company building an actual physical server farm.^[3]

Architecture

Map showing the approximate geographical regions used by Amazon Web Services.

AWS is located in 12 geographical "regions": US East (Northern Virginia), where the majority of AWS servers are based,^[4] US West (northern California), US West (Oregon), Brazil (São Paulo), Europe (Ireland and Germany), Southeast Asia (Singapore), East Asia (Tokyo, Seoul, Beijing) and Australia (Sydney). There is also a "GovCloud", based in the Northwestern United States, provided for U.S. government customers, complementing existing government agencies already using the US East Region.^[5] Each Region is wholly contained within a single country and all of its data and services stay within the designated Region.

Each Region has multiple "Availability Zones", which are distinct data centers providing AWS services. Availability Zones are isolated from each other to prevent outages from spreading between Zones. Several services operate across Availability Zones (e.g., S3, DynamoDB) while others can be configured to replicate across Zones to spread demand and avoid downtime from failures. As of December 2014, Amazon Web Services operated an estimated 1.4 Million servers across 28 availability zones.^[6]

With respect to power provisioning for centers in the regions, AWS stated in 2014 a commitment to achieve 100% renewable energy usage.^[7] As part of this effort in the United States, AWS commissioned with Community Energy of Virginia a solar farm coming online in 2016 to support the US East region.^[8] Further, as of 2015, AWS is working with Tesla Motors to apply battery storage technology to address some power needs in the US West (Northern California) region.^[8]

History

AWS Summit 2013 event in NYC.

Officially launched in 2006, Amazon Web Services provides online services for other web sites or client-side applications.^[1] Most of these services are not exposed directly to end users, but instead offer functionality that other developers can use in their applications. Amazon Web Services’ offerings are accessed over HTTP, using the REST architectural style and SOAP protocol. All services are billed based on usage, but how usage is measured for billing varies from service to service.

In late 2003, Chris Pinkham and Benjamin Black presented a paper describing a vision for Amazon's retail computing infrastructure that was completely standardized, completely automated, and would rely extensively on web services for services such as storage, drawing on internal work already underway. Near the end they mentioned the possibility of selling virtual servers as a service, proposing the company could generate revenue from the new infrastructure investment.^[9] The first AWS service launched for public usage was Simple Queue Service in November 2004.^[10] Amazon EC2 was built by a team in Cape Town, South Africa, under Pinkham and lead developer Chris Brown.^[11]

In June 2007, Amazon claimed that more than 180,000 developers had signed up to use Amazon Web Services.^[12]

In November 2010, it was reported that all of Amazon.com retail web services had been moved to AWS.^[13]

On April 20, 2011, some parts of Amazon Web Services suffered a major outage. A portion of volumes using the Elastic Block Store (EBS) service became "stuck" and were unable to fulfill read/write requests. It took at least two days for service to be fully restored.^[14] On June 29, 2012, several websites that rely on Amazon Web Services were taken offline due to a severe storm of historic proportions in Northern Virginia, where Amazon's largest datacenter cluster is located.^[15]

On October 22, 2012, a major outage occurred, affecting many sites such as Reddit, Foursquare, Pinterest, and others. The cause was a latent memory leak bug in an operational data collection agent.^[16] On December 24, 2012, AWS suffered another outage, causing websites such as Netflix instant video to be unavailable for customers in the Northeastern United States.^[17] Amazon later issued a statement^[18] detailing the issues with the Elastic Load Balancing service that led up to the outage.

In November 2012, AWS hosted its first customer event in Las Vegas.^[19] On April 30, 2013, AWS began offering a certification program for computer engineers with expertise in cloud computing.^[20]

On May 13, 2013, AWS was awarded an Agency Authority to Operate (ATO) from the U.S. Department of Health and Human Services (HHS) under the Federal Risk and Authorization Management Program (FedRAMP).^[21]

AWS adoption has increased since launch in 2006. Customers include NASA,^[22] the Obama Campaign,^[23] Pinterest,^[24] Kempinski Hotels,^[25] Netflix,^[26] Infor,^[27] the CIA.^[28]

AWS revenue was not stated separately in the past, but in 2012 it was estimated by industry watchers at over US$1.5 billion.^[29]

In April 2015, AWS was reported to be profitable, with sales of US$1.57 billion in the first quarter of the year, and US$265 million of operating income. Founder Jeff Bezos described it as a fast-growing US$5 billion business; analysts described it as "surprisingly more profitable than forecast".^[30] In October 2015, Amazon.com said in its Q3 earnings report that AWS's operating income was $521 million, with operating margins at 25 percent. AWS's Q3 2015 revenue was $2.1 billion, a 78% increase from Q3 2014's revenue of $1.17 billion.^[31]
