The Metropolitan Area Grid or Metropolitan Grid are a new kind of Grid implementation that beginning to diffuse quickly for scientific and business applications.
Today many Universities, research institutes and business center, have equiped thier departements or sections, with computational and storage resources for High Performance Computing. Often this institutions can taken advantage of broadband network links between the centers distributed in a metropolitan or regional scale.
In this scenario the distributed computing is a fundamental requirement in order to resolve computational hard problems, increase the collaboration and optimize the investments
