Abstract

Dependable computer systems hosting critical commerce,transportation, and military applications, amongothers, must satisfy stringent quality-of-service (QoS)requirements. However, as these systems become increasinglycomplex, maintaining the desired QoS bymanually tuning the numerous performance-related parameterswill be very difficult. This paper developsa generic online control framework to designself-managing computer systems. The proposed approachexplores a limited region of the systemstate-space at each time step and decides the best controlaction accordingly. We present two case studiesto demonstrate the practicality of the proposed controlframework.
