Earlier quoted context omitted.
That's a good point. But I am curious how special this Classic offering was, compared to what came after. Would migration have been hard?
It's not so much that EC2 Classic offered any features that were difficult to live without. It's just that migraine away from it means migrating, period. You need to move all of your systems, including any data stored on those systems (in instance store or EBS), to effectively a new data center. Migrating a live production environment can be a pain and/or cause downtime.
Freudian slip?
