But I have to deploy stub functions and have a different deployment model for prod. :) So there are definitely tradeoffs.
I like this idea and will certainly try it out!
What I was really hoping for is someone who could figure out a way to launch a terminal in Lambda so that I can modify my functions in place and view the logs in place, and then when I'm done, save my work to git, like I used to be able to do when I had a fleet of servers and could just log onto one of them in prod and muck around with logs (and yes I know this is a bad idea but it's also how things get done quickly).
