Over the past years the Department of Defense and the Army have been working to accelerate toward wide-scale adoption of cloud computing for the potential cost saving and enhanced mission capabilities that it brings. The Live, Virtual, Constructive – Integrating Architecture (LVC-IA) is a Program of Record (POR), under the Army Program Executive Office for Simulation, Training, and Instrumentation (PEO STRI) Project Manager for Integrated Training Environment (PM ITE), which provides a net-centric linkage for existing Training Aids, Devices, Simulations, and Simulators in an ITE. To date the LVC-IA architecture utilizes a series of servers which are physically located in one or more fielding sites. Each instance of an LVC-IA system has to be individually installed and maintained at each site. Building and running these on site systems is complex and expensive. With each instantiation of LVC-IA for the new training sites, the capital and operating expenditures would simply multiply. A research effort was sponsored by PM ITE to evaluate the feasibility of leveraging cloud computing for LVC-IA. This paper summarizes the analysis conducted, architecture design, and prototype implemented from this research effort. The paper dives into the Information Assurance issues encountered and touches on processes from other Army programs as they relate to the Common Operating Environment (COE) Data Center/Cloud (DC/C) Computing Environment (CE). The paper also reports the comparative analysis results between an ITE with co-located LVC-IA versus an ITE with LVC-IA in the cloud. Finally the paper reports the challenges uncovered, lessons learned, and recommended way forward.
