Amazon S3 (Simple Storage Service) is a web service offered by Amazon Web Services. Amazon S3 provides storage through web services interfaces (REST, SOAP, and BitTorrent). Amazon launched S3 on its fifth publicly available web service, in the United States in March 2006 and in Europe in November 2007.
At its inception, Amazon charged end users US$0.15 per gigabyte-month, with additional charges for bandwidth used in sending and receiving data, and a per-request (get or put) charge. On November 1, 2008, pricing moved to tiers where end users storing more than 50 terabytes receive discounted pricing. Amazon says that S3 uses the same scalable storage infrastructure that Amazon.com uses to run its own global e-commerce network.
Amazon S3 is reported to store more than 2 trillion objects as of April 2013[update]. This is up from 10 billion as of October 2007, 14 billion in January 2008, 29 billion in October 2008, 52 billion in March 2009, 64 billion objects in August 2009, and 102 billion objects in March 2010. S3 uses include web hosting, image hosting, and storage for backup systems. S3 guarantees 99.9% monthly uptime service-level agreement (SLA), that is, not more than 43 minutes of downtime per month.
Amazon does not make details of S3's design public, though it clearly manages data with an object storage architecture. According to Amazon, S3's design aims to provide scalability, high availability, and low latency at commodity costs.
S3 is designed to provide 99.999999999% durability and 99.99% availability of objects over a given year, though there is no service-level agreement for durability.
