Cloud Computing is evolving so quickly. Usually HPC and Enterprise Computing are usually very seperate with distinct characeristics and usually it does not converge so easily.
Cloud Computing which is the natural evolution of virtualisation and consolidation and usually comes from the Enterprise Computing paradigm is finally closing the gap of this convergence.
One important development can be seen from Rocky Mountain Supercomputing Centers (RMSC) may be one of the first HPC Cloud being developed with the concept of supercomputing on the demand concept or Supercomputer platform as a service (SPaaS). See Rocky Mountain Supercomputing Centers (RMSC) offering.
Very thought provoking
