Intercloud for simulation federations

Education training and experimentation networks (ETEN) are an important application area for the cloud computing concept. An ETEN is an infrastructure that consists of advanced distributed learning, collaborative working and distributed simulation systems, and can be designed as an intercloud of many global and private clouds. Intercloud approach introduces new opportunities to improve the performance and to increase the utilization of distributed simulation systems in an ETEN. These improvements also imply significant reduction both in the initial investment and operations/maintenance costs of ETEN. Our new ETEN intercloud concept including challenges and their technical solutions are introduced. We also carried out a large standalone experiment and tests during exercises. The preliminary results from these experiments are presented.
