The OpenNebula Cloud offers a virtual computing environment accessible through two different remote cloud interfaces, OCCI and EC2, and through two web interfaces, OpenNebula Sunstone and OpenNebula SelfService. These mechanisms access the same infrastructure, i.e. resources created by any of the mentioned methods will be instantly available on the others. For instance, you can create a VM with the OCCI interface, monitor it with the EC2 interface, and shut it down using the OpenNebula Sunstone web interface.

We offer a 'dummy' cloud intended to try out the different access mechanisms. Operations upon this cloud will result on virtual networks and machines resource creations, but no real action whatsoever will be performed. This means that there will be the ilusion that a VM is created, but in fact it won't be running anywhere. This is a great way to test the interfaces behaviour and to develop clients on top of them, and also to try the Sunstone Web UI.
