What's the issue with logging? I would have expected stdout/stderr to get automatically transferred to the providers managed logging solution (e.g. cloudwatch).
Though I never really understood the appeal of FaaS over something like Google-Cloud-Run.
As a developer who spent a couple months developing a microservice using aws lambda functions:
it SUCKS. There's no interactive debugging. Deploy for a minute or 5 depending on the changes, then trigger the lambda, wait another 5 minutes for all the logs to show up. Then proceed with printf/stack trace debugging.
For reasons that I forgot, locally running the lambda code on my dev box was not applicable. Locally deploying the cloud environment neither.
I wasn't around for the era but I imagine it's like working on an ancient mainframe with long compile times and a very slow printer.
