Despite a rocky 2011, Amazon Web Services (AWS) continues to
stand out among other cloud service providers. Recently, it added object
expiration to S3 files, making it easier to manage temporary files/logs/etc. on
Object expiration will allow developers to establish clear
rules for automatically deleting files stored in S3. This addition follows up
another new feature, multi-object deletion, which makes getting rid of multiple
files (and other things) in an S3 bucket considerably quicker.
Unfortunately, multi-object deletion is capped at 1000
objects and must be done manually. Now, developers can set up guidelines for
deleting files with a specific prefix, as well as the expiration period for
objects (in days).
It should be noted, however, that Amazon warns about “a
small lag between the expiration date and the date at which Amazon S3 removes
an object,” but that it won’t charge for storage of objects past their
