Strongly agree. I loved AWS Lambda both for pricing and for developer convenience/efficiency, but managing the network infrastructure beneath it finally irked me too much, so I switched to pushing a Docker container to Heroku and haven't looked back. I am tempted to believe that a lot of teams might be forcing themselves into over-engineering/overkill to jumping right to AWS where it's not needed.

I have read similar comments to the ones here about scaling and cost, so I might bump into that at some point.
