Amazon S3 Concepts:

BUCKETS:

A bucket is a container for objects stored away in Amazon S3. Each object is contained in a bucket. Bucket serves for multiple needs: they arrange the Amazon S3 namespace at the most highest level. they recognize the account responsible for storage and information transfer charges, they assume a part in get to control, and they serve as the unit of total for usage report.
