Grid-based computing platformfor large-scale online applications

With the vast amount of computing resources available across the Internet, basic communication and programming mechanisms have been evolving fromsimple client/server socket communication model to object-oriented middleware systems, and lately, to the Grid computing service system platform. Nowadays, computers can be interconnected with networks to create high-performance parallel, distributed, and clustered computing systems. From a networking design perspective, the system modelhas moved from a basic multiple-to-one client/server system to a peer-to-peer model. In this chapter, we review the foundation technologies that have been developed into the Grid computing. Different algorithmic designs for overlay networks are also discussed. We then investigate the design of Grid computing operating platform for serving largescale real-time online applications.
