I suppose if you're using an API to run the CLI, that could be asked in Stackoverflow, but might not be best.
I don't have the question handy, but saw that a question was closed as off topic because it related to aws-cli itself, which isn't a Linux distro.
Maybe group all VPS stuff into one stack?

Flagged to close because the AWS command line tools are not platform specific, nor are any of the problems mentioned here. – Evan Carroll Apr 22 '16 at 16:16
This question:
https://unix.stackexchange.com/questions/336179/can-i-send-e-mails-from-amazon
will be closed. It's not really a programming question...
makes me wonder. migrate to where?
/amazon-ec2
tag. The email question is now, for me, a 404 page, so I can only guess, but it might have been on topic there too. Or, if it was from a web master point of view, then it might have fit on Pro Webmasters, which also deals with AWS hosting.
