Modern Internet Services

Modern World Wide Web provides a variety of services §ranging from e-mail and social networking to banking §and shopping. It is difficult for service providers §to manage these Internet services, because: (1) they §exhibit complex structural organization, where §component middleware (such as Java EE) is often used §as building platform, and (2) complex session-§oriented client behavior makes it hard to predict §what impact service management mechanisms will have §on application behavior. This book presents several §new and novel Internet service management techniques §that target two interconnected goals: (1) providing §improved Quality-of-Service guarantees to the service clients, and (2) optimizing server resource §utilization. These mechanism are representatively §chosen to validate the claim that exposing and using §detailed information about how clients use Internet §services enables mechanisms that achieve the range §of goals listed above. This book should be useful to §all professionals working in the area of Internet §services, or anyone else who may be interested in §the latest developments in this exciting area of §distributed computing systems research and practice.
