Single page of instructions from google apps has me download a tarball, add a hello world command, and Presto! I have a webapp on my computer! Then change this one line and PRESTO! My webapp is in the cloud!! No telling how, or with what components, or what the dependencies or security implications are, or how to see the logging for the app. Just a single paragraph of instructions and you can be the next internet startup IPO! 'Hail Mary' is the best way to describe the situation I've yet heard.
