The pace of innovation in computer and networking technology allows many new IT services to emerge rapidly and often benefit from new network services that support faster connectivity and better performance. Centralized resources that are used to provide services to customers are impractical in a dynamic service-based system owned by multiple organizations. The new service oriented business environment enables service providers to dynamically integrate services across networks according to their customers' needs. This is achieved by exploiting IT resources that are easy to access no matter where they reside. For example, network service providers offer bandwidth to customers who are interested in buying content (e-books, music, and streaming media) from web sites (content providers) or virtual machines (supporting operating systems or processes) from Amazon (grid service providers).
