I haven't read any of your other posts and my comments were not directed to you in particular. You're really making my point. If cloud formation templates work then great. I don't know its limitations. I do know that kubernetes has become a standard for orchestration and that it becomes easier over time to manage. A couple years ago there was no support from AWS so maybe not the time to jump in. Likewise with Kafka. Cool tech but really expensive to manage. Now AWS and Confluent will manage so the costs have come way down.
But we really don't care about the lock in boogeyman. Out of all of a typical business's risk, lock in is the least of them. We use lambda where feasible, Fargate (serverless Docker) when necessary. Why waste time doing the "undifferentiated heavy lifting"?
