We need to do this given how fast AWS is continuing to grow; we will start to run low on IDs for certain EC2 and EBS resources within a year or so.

It is amazing to see how fast the transformation and growth is happening from datacenter to cloud.  This change is not much of a technical challenge.

The new IDs will be the same format as existing IDs, but longer. The current ID format is a resource identifier followed by an 8-character string, and the new format will be the same resource identifier followed by a 17-character string.

We have already made the change to support the longer instance ids and look forward to the seamless change.
