Abstract
Service high availability is becoming a must in various domains. Services provided by applications originally not designed for high availability can be rendered highly available by integrating them with a middleware compliant to the SAForum specification. Such a middleware offers a number of configuration options. The assessment of service availability at the design of the system configuration facilitates the selection of a system configuration, which is optimal with respect to specific priorities. In this paper we present a case study of turning a legacy video streaming application into a highly available one. We present our methodology, and then we analyze the availability we can expect from the application in various configurations and settings.
