Amazon S3 (Simple Storage Service) is a web service offered by Amazon Web Services. Amazon S3 provides unlimited storage through a simple web services interface. Data can be easily stored and retrieved at any time, from anywhere on the web.

Amazon S3 is an inexpensive storage solution using the same scalable storage infrastructure that Amazon.com uses to run its own global e-commerce network.

Launched in March 2006, Amazon S3 is currently being used by small start-ups and enterprise clients as a web hosting service, image hosting service, back-up system, and more. Amazon S3 clients include Microsoft, Xerox Global Services, Linden Lab (Second Life), Sentillion, Webmail.us, RenderRocket, ElephantDrive, Powerset, Zonbu, MyDatabus and iConclude.

S3 Design

Amazon S3 is designed to provide an online storage service that is inexpensive, scalable, responsive, and highly reliable.

S3 stores arbitrary objects up to 5 gigabytes in size, each accompanied by up to 2 kilobytes of metadata. Objects are organized into buckets (each owned by an AWS account), and identified within each bucket by a unique, user-assigned key.

Buckets and objects can be created, listed, and retrieved using either a REST-style HTTP interface or a SOAP interface. Additionally, objects can be downloaded using the BitTorrent protocol.

Authorization is done using an access control list associated with each bucket and object.

Bucket names and keys are chosen so that objects are addressable using HTTP URLs:

http://s3.amazonaws.com/bucket/key
http://bucket.s3.amazonaws.com/key
http://bucket/key (when bucket is a DNS CNAME record pointing to s3.amazonaws.com)

Because objects are accessible by unmodified HTTP clients, S3 can be used to replace significant existing web hosting infrastructure. (Notable examples include photo sharing website SmugMug,^[1] and web desktop YouOS.^[2])
