Deltacloud standard cloud service interface

Deltacloud is proposed as a standard way to interface to cloud service providers, such as Amazon EC2. The idea is that you can then move to other providers easily. However, the details of support for networking, authentication and accounting are still to be finalised. Delatacloud was developed by Red Hat and is proposed as an Apache open source project (which has disadvantages as well as advantages). There is a Deltacloud Website, Deltacloud git repository and Deltacloud mailing list.
