Deltacloud is a Ruby gem which removes the differences between APIs of various cloud service providers and offers a single API that can communicate with them.

It is a simple and easy-to-use REST API which already supports Amazon EC2, GoGrid, Rackspace, OpenNebula, RimuHosting and more.

Deltacloud - Cloud API

There is also an open source and web-based interface, Deltacloud Aggregator, which enables you to:

  • view image status and stats across clouds, all in one place
  • migrate instances from one cloud to another
  • manage images locally and provision them on any cloud

The API is great for any Ruby developer who is using cloud services as there may always be a need for switching providers.
