We examine some of the problems associated with managing a server farm, that is, a collection of servers which are used to provide different types of services to paying customers. The users are charged for the services provided, but are also promised that certain Quality-of-Service (QoS) criteria will be met. Failure to satisfy those QoS undertakings incurs pre-specified penalties. In order to maximize the revenue obtained, the service provider must employ intelligent dynamic policies dealing with server allocation and job admission decisions. A number of such policies are surveyed.

Key Words: service provisioning • cloud computing • quality of service • revenue maximization • server allocation • admission policies

Handling editor: Erol Gelenbe
