The cloud providers are splitting into a few camps. On one side, you have

and no server administration, but it locks you into a specific provider.
Enter Engine Yard, a company that's enhancing Ruby on Rails to run on on top of
arbitrary IaaS. In this interview Ezra Zygmuntowicz paints the picture.

service (PaaS) providers. IaaS (like Amazon Web Services) is basically
virtual machines in the sky, and this differs from traditional hosting because
with a cloud provider, you should be able to start and stop dozens or hundreds
of VMs through an API, and pay only for the CPU hours you use. PaaS (like
Google App Engine) gives you a framework to code against, and it's a much more
restrictive environment (moving to PaaS is usually a rewrite), but you never
worry about individual machines, patching, or all that Jazz.
In this interview, we explore the concept or layering an arbitrary PaaS
implementation on top of an arbitrary IaaS provider. Hmmm…
