You can arbitrage AWS with your own servers as long as network costs don't eat you. Run say a TravisCI type service on your own hardware? The big lockin is network pricing. No egress fees when their data is already in S3. You have to run where the consumer has their data or you eat that network transfer as overhead for your SAAS. I see GitHub slowly charging for egress downloads as the next lockin. You "save" by paying for builds on Azure.
