we do have an aws lambda function deployment package (that uses a pex file, though) in contrib/: https://github.com/pantsbuild/pants/tree/master/contrib/awslambda/python/src/python/pants/contrib/awslambda/python, so this is the kind of thing we'd be interesting in supporting, i think. i'm not sure what the requirements are for google cloud, but it seems reasonable for pants to be able to support that, although i don't know if we'd put it in the main pants repo unless there's a commitment to maintain it -- but you can write pypi packages which export pants plugins, or write plugins in your repo using pants: see https://www.pantsbuild.org/dev.html. if you open an issue we can definitely help with that.
