Depends on the issue - if there's a code / logic bug that doesn't affect the data schema, we use elastic beanstalk versions to go back the previous version (usually this is a rolling deploy backwards), and then clean up the data manually if necessary. Otherwise, we roll forward (fix the bug, clean up the data, etc). It's more often been the case for us that issues are caused by mistaken configuration / infrastructure updates. We do a lot of IAC (Chef, Cloudformation), so with those, it's usually a straight git revert and then a normal release.
