Abstract:
Mission Critical Systems (MCS) require continuous operation since a failure might cause economic or human losses. Autonomous Decentralized Service Oriented Architecture (ADSOA) is a proposal to design and develop MCS in which the system functionality is divided into service units in order to provide functional reliability and load balancing; on the other hand, it offers high availability through distributed replicas. A fault detection technology has been proposed for ADSOA. In this technology, an operational service level degradation can be detected autonomously by the service units at a point in which the continuity of the service may be compromised. However, this technology is limited because it requires human supervision for recovery. In this paper, we propose an autonomous recovering technology, which detects and instructs to service units to be gradually cloned in order to recover the operational service level. A prototype has been developed in order to verify the feasibility of this technology.
