ENSCO has past performance in transitioning HPC cloud compute to external cloud (AWS, etc).  This will extend efforts to modeling and simulation (M&S) software and provided developmental HPC network for all M&S by deploying and optimizing a range of M&S needs including but not limited to: Mission planning tool, meteorology, hydrology.  ENSCO proposes to develop a prototype transitional cloud platform that will allow the government to assess a scalable cloud HPC system on AWS which can be tested against each mission area requirements in a phased approach.
