For cost efficiency, we should reduce our usage of EBS resources. We can do this as follows:

  • delete all volumes not actively in use by an instance. Volumes can be recreated at will from snapshots.
  • Set up a cron job to periodically delete unused volumes and snapshots. See the snapshot_utils code you have to set up a lambda function for this.
  • In two weeks, delete all AMIs that are not currently referenced in a CFN stack. Send out an email to notify on this.
  • Delete all unattended instances older than 6 weeks.
