Welcome to Amazon S3

This is the Amazon Simple Storage Service (Amazon S3) Developer Guide. It explains Amazon S3 core concepts of buckets, objects and how to work with these resources using the available APIs. It describes how you send requests to create buckets, store and retrieve your objects, and manage permissions to your resources. The guide describes both the access control and the authentication process. The access control defines who can access objects and buckets within Amazon S3, and the type of access (e.g., READ, WRITE, and so on). The authentication process verifies identity of a user trying to access Amazon Web Services (AWS).

Amazon Simple Storage Service (Amazon S3) is a web service that enables you to store data in the cloud. You can then download the data or use the data with other AWS services, such as Amazon Elastic Cloud Computer (see Amazon Elastic Compute Cloud (Amazon EC2) ).
