Underutilized distributed servers waste power and energy due to inefficient power supplies, a proliferation of network interface cards, and an overabundance of supporting network switches, hubs, and routers. Further, distributed systems architectures are rife with program-to-program interoperability issues—such as communicating between Microsoft .NET, Java 2 Enterprise Edition (J2EE), and legacy programming models—and these interoperability issues also hamper the efficiency of business processes…
