In an ASP server farm, requests to use an application are directed to a particular executing instance of the application (or an appropriate component thereof) that is identified as being the least loaded of the available such instances of the application or its component. The number of such instances is dynamically increased or decreased in response to the number of requests for the application or components thereof. Requests may be directed (in accordance with the first aspect) or the instances adjusted (in accordance with a second aspect) on a per client-basis, in which instances of the application and/or components thereof are reserved for the use of a user or a particular group of users. Operation in this manner facilitates compliance with service agreements with respective users or groups of users.

Managing server resources for hosted applications

A method, apparatus, computer program product, and decision support system and for allocating hosting-service resources to clients in at least one shared server. The method comprises discovering utilization patterns of the clients; monitoring the clients to discover the utilization patterns; providing bounds specifying minimum and maximum hosting-service resources for each of the clients; modeling dimensions for client user measures and the utilization patterns; and allocating the resources to the clients dependent on the utilization patterns. The step of allocating is also dependent upon the bounds. The method further includes packing the clients using stochastic vectors, wherein the packing step utilizes at least one of a Roof Avoidance process, a Minimized Variance process, a Maximized Minima process, and a Largest Combination process, and wherein the hosting-service resources relate to at least one hosting comprising one of collaborative hosting services, commerce hosting services, and e-business hosting services.
