I appreciate that they have made globally deploying a rails app, Postgresdb, cdn, network routing fast and easy. There is always lot of finicky configuration issues and it takes a lot of time to get this all set up right. Like lots of IaaS, they are making something hard easier. They are not, though, removing the need to build your app to this paradigm. The conventions and restrictions you need to follow to realize the benefits remain and are similar to what you’d have to do yourself. So they’ve cleaned up lots of application and deployment gunk, but the app engineering work remains. This is progress. Very nice.
