An Integrated Business Rules and Constraints Approach to Data Centre Capacity Management

A recurring problem in data centres is that the constantly changing workload is not proportionally distributed over the available servers. Some resources may lay idle while others are pushed to the limits of their capacity. This in turn leads to decreased response times on the overloaded servers, a situation that the data centre provider wants to prevent. To solve this problem, an administrator may move (reallocate) applications or even entire virtual servers around in order to spread the load. Since there is a cost associated with moving applications (in the form of down time during the move, for example), we are interested in solutions with minimal changes. This paper describes a hybrid approach to solving such resource reallocation problems in data centres, where two technologies have to work closely together to solve this problem in an ecient manner. The rst technology is a Business Rules Management System (BRMS), which is used to identify which systems are considered to be overl...
