Working with Objects
Objects are the data that you store in Amazon S3. Every object resides within a bucket you create in specific AWS region.
Objects stored in a region never leave the region unless you explicitly transfer them to another region. For example, objects stored in the EU (Ireland) region never leave it. The objects stored in an Amazon S3 region physically remain in that region. Amazon S3 does not keep copies or move it to any other region. However, you can access the objects from anywhere, as long as you have necessary permissions.
Before you can upload an object into Amazon S3, you must have write permissions to a bucket.
Objects can be any file type: images_backup, data, movies, etc. An object can be as large as 5 TB. You can have an unlimited number of objects in a bucket.
This section explains how to use the console to create, manage, and delete objects.
