Enforcing User-Defined Management Logic in Large Scale Systems

The ubiquity of information technology, technological advances, and utility computing trends have motivated large-scale systems, but managing and sustaining these systems is far from trivial. Automatic or semi-automatic monitoring and control are a potential solution to this problem. However, since management scenarios differ from system to system, a generic management framework that can manage a wide variety of systems should support user-defined management logic. This paper proposes a novel architecture that can manage large-scale systems according to user-specified management logic that depends on both global and local assertions of the managed system. Furthermore, the paper demonstrates that despite having a global view of the managed system, a management framework can scale to manage most real world use cases.
