Abstract

When deployed as operational components of production systems, novel computer services are supposed to respond synchronously to real-world events associated to the business process they implement, thereby needing to meet temporal constraints dictated by the dynamics of the environment in which they operate. This elicits a real-time system approach. One emerging concept to cope with such unpredictability of large-scale distributed computer applications is the use of feedback control principles. This paper introduces a feedback-based adaptive resource control algorithm for composite applications implementing real-time business process. The study is based on recent achievements in the field and ongoing progresses. A brief background on the field, the rationales of the proposed techniques and development results are presented.
