Amazone S3 is a scalable, web-based cloud storage service for application programs and online backup and archiving of data at high speed and at low cost. To make web scale computing for developers as simple as possible, Amazon S3 was intentionally designed to offer a minimal feature set. Amazon S3 is an object storage service. The concept of object storage is different from file and block storage. Each object is filed together with an identification number and associated metadata. Applications use this identification number to access an object.
