We have about 30 websites with almost no traffic (<~10 visits/day) which are currently hosted on a dedicated server.
We are evaluating hosting on Amazon EC2 however I'm not sure how to do that properly.
- One (micro) instance per website is too expensive
- ~10 websites on one instance (using apache virtual hosts) make auto-scaling impossible (or at least difficult)
Or is cloud computing not suitable for such a use-case?
