> You can do 10x cheaper than AWS easily, if you are willing tomake tradeoffs that AWS just can't make globally for all their customers.

Are you really replicating AWS or just EC2? How do you replicate S3? Glacier? What about Aurora (DB replication that actually works!). If all I need is raw compute, I can go back to building machines and beat AWS prices but I will have no where near the same level of functionality, flexibility, and now it is up to me to maintain them.
