Yes! You read right!
It's possible to transform a physical cluster into a flexible and elastic virtual infrastructure, separating resource provisioning from job execution management, and supporting the dynamic adaptation of a virtual EGEE site to the users’ computational demands.
You don't believe it? Then visit Booth 4 during this afternoon's Demo Session. You'll see how a virtual infrastructure, managed by the OpenNebula VM Manager, will run on local and Cloud resources, so automatically scaling out the local infrastructure in order to meet peak demands.
