Availability "weak point" analysis over an SOA deployment framework

— Availability is one of the important factors to be considered for business-driven IT service management. This paper addresses the issue of analyzing what we call availability weak-points in an SOA deployment framework, leveraging workflow definitions to specify the high availability requirement at the business process level. In our weak-point analysis framework, we present an effective analysis methodology to calculate the optimal high availability solution with minimum cost, while meeting the business level availability requirements. We evaluate the weakpoint analysis methodology, and show that our methodology can identify a near-optimal solution for availability enhancement over the SOA deployment framework.
