AWS migrating from 8-character to 17-character resource IDs.

[Exide]

AWS is transitioning resource IDs to a longer format. The old format is a resource identifier followed by an 8-character string, and the new format is a resource identifier followed by a 17-character string. You have until July 2018 to opt in to the longer format.

If you do not take any action, you will be opted in automatically in July 2018, when all new resource IDs will be created with the longer format. Until the deadline, you can opt in and out of the new format as needed. Only newly created resources receive longer IDs; existing resources are unaffected.

Let's make sure this doesn't bite us.
