I know Heroku is pretty painless except when trying to do weird things (use a wildcard certificate from let's encrypt comes to mind, though it might be OK now) where it can become weirdly complicated as we have to think about stuff that was hidden before (how are the request routed ? how is the certificated handled ? how to renew it ? etc) How does App Engine compare ? From a bird's eye, it seems a lot of configuration is still needed to communicate within Google's ecosystem and as Google also pushes k8s, I wondered how much resources they were putting in App Engine to have it run smoothly vs k8s where they are the main driver force and have a natural advantage over the concurrents.
