Open Source Cloud APIs Vie For Dominance

As of Red Hat’s news last week, there are now four competing standards for building so-called open source clouds. It’s shaping up to be quite a battle of the titans. Contenders are: Amazon Web Services via Eucalyptus Systems; Rackspace and OpenStack, Cloud.com and Cloudstack; Red Hat’s DeltaCloud. Companies like Intel, Dell, Citrix, HP, IBM, Cisco are all lining up behind one or more. But some experts says that the ultimate standard may not even have shown itself yet.
