Grid and utility computing promises a bright future

摘要

A bright future is promised ahead for Grid computing, a technology expected to become a popular enabling means for business applications. Today, most business applications are developed on top of systems depending on costly 'islands of computation', with each application needing its own dedicated machines and software. Grid computing breaks the barries and bridges the gaps by bringing together 'resources islands', forming virtualized computing resources. Further, it opens the door to utility computing to provide electric utility like services. This service orientation shift has resulted in new challenges and opportunities for Grid research and development.
