Adaptive Compensation Mechanism Considering the Interaction of SLA and Manages for Web Services Management System

Abstract

The Web Service has become one of promising technologies, and is getting widely adopted in business and also gradually deployed in real customer environment. The technology of Web Service is capable of providing a means to integrate different functional components over Internet and enabling business entities to interact one another through standard application program. The Quality of Services (QoS) plays an important role for Web Services in consequence of Web Service is a dynamic system which contains some unexpected factors. Users are desirous of service that they are offered with guarantee consequently the concept of Service Level Agreement (SLA) is growing momentous by degrees. Consequently, service provider and service requester each takes what they need under the protection of SLA. This paper proposed an SLA-based Web Services Management System for Auto-Compensation. The System aims to manage and monitor the SLA that had been negotiated between the service requester and the service provider. The system would handle the violation with some appropriate functionality while any actions infringe on SLA. While the efficiency and quality of the Web Service performance becomes lower, the system could discover the problems and operate compensation in advance. Service requester makes use of the service as usual and service provider has taken the necessary precaution beforehand. Both sides could benefit from it and construct the constant relationship.
