Every object that you add to your S3 bucket is associated with a storage class. All the available storage classes offer high durability. You choose how you want to store your objects based on your application’s performance access requirements.
At present, you can use the following storage classes with S3:
- STANDARD: default for frequently accessed data
- STANDARD_IA: for infrequently used data that needs to be retrieved rapidly when requested
- ONEZONE_IA: for the same use case as STANDARD_IA, but stores the data in one Availability Zone instead of three
- REDUCED_REDUNDANCY: for frequently used noncritical data that is easily reproducible
If you want to change the storage class of an existing object, you need to recreate the object.
