For all intents and purposes, Microsoft Azure and Google Cloud Platform have already replicated EC2 and S3, and every other feature they think is worth it. The price war in 2014 was pretty brutal (unless you're a customer, of course!) and it's not going to slow down in 2015.

And as people move away from 'raw cloud metal' to whatever the layer du jour is, what's underneath will matter less and less.
