Service centric computing – Next generation internet computing

Abstract

In the not-too-distant future, billions of people, places and things could all be connected to each other and to useful services through the Internet. In this world scalable, cost-effective information technology capabilities will need to be provisioned as service, delivered as a service, metered and managed as a service, and purchased as a service. We refer to this world as service centric computing. Consequently, processing and storage will be accessible via utilities where customers pay for what they need when they need it and where they need it. This tutorial introduces concepts of service centric computing and its relationship to the Grid. It explains a programmable data center paradigm as a flexible architecture that helps to achieve service centric computing. Case study results illustrate performance and thermal issues. Finally, key open research questions pertaining to service centric computing and Internet computing are summarized.
