I have a story of a "serverless" hack. It's ugly, but you might appreciate it:
There was a company that I worked with that used AWS lambda with Go lang binaries. They did this by having the python runtime "exec" the binary with the python subprocess.popen api. As long as the binary and the python bootstrap script were packaged together it worked fine. I used similar tricks to get native C crypto libraries to work from python in AWS lambda.
