Design of Autonomic SLA Manager for Service Applications

Internet-based businesses become more profitable, and their business scopes are extended, mainly due to new effective IT paradigms characterized by service- oriented computing and autonomic computing. The technologies offered by these paradigms provide a new way of managing e-Business services and infrastructures with minimum human intervention, i.e. autonomous fashion. However, the dynamic nature of service-oriented architecture (SOA) makes such autonomic management harder. More specifically, defining events, monitoring services, and analyzing anomalistic behavior are quite cumbersome. Autonomic SIA Manager is a cost-effective and robust solution to the problems. In this paper, we present the architecture of Autonomic SIA Manager (ASM), its main components, such as policy decision-making language, interface wrapper, autonomic service event handler. We also conduct a case study to show how ASM manages the SIA effectively.
