dotCloud: federating clouds without reinventing the wheel
What is dotCloud?
dotCloud is a framework for distributing and deploying cloud applications across different infrastructures, with different data.
With dotCloud you can package your servers as stateless components that can be versioned and distributed with Mercurial. Components can then be packaged together into complete, multi-server applications, which you can also keep under version control.
dotCloud components, and groups of components, can be instanciated any number of times on different cloud infrastructures (Xen, VMWare, KVM or bare metal), and with different data. For example, you could deploy an identical clone of your entire backend for staging purposes, in just one line.
Persistent data is organized in simple volumes which can be rsynced from cloud to cloud, and mapped on any storage mechanism (local storage, NAS, S3, Amazon EBS, etc.)
