Amazon S3 Objects

• Each object is stored and retrieved by a unique key (ID or name).

• An object in S3 is uniquely identified and addressed through:

  • Service end point.
  • Bucket Name
  • Object Key
  • Optionally an object version

• Objects stored in a bucket will never leave the region in which they are stored unless you move them to another region or enable cross-region replication.

• You can define permissions on objects when uploading and at any time afterwards using the AWS management console.
