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 weak-point analysis methodology, and show that our methodology can identify a near-optimal solution for availability enhancement over the SOA deployment framework.
