1 Introduction
In this work, we evaluate how crashes, failovers, and recoveries affect the performance and availability of RobustS tore, a highly available dynamic content web application. RobustStore has been implemented by retrofitting the stand-alone on-line bookstore specified by TPC-W [6] with Treplica, a middleware for building dependable applications [22]. Thus, the assessment of RobustStore is, in fact, the assessment of the fitness of Treplica as a high-availability support for dynamic content web applications. The TPC-W benchmark, augmented with faultloads and dependability measures, is used to evaluate the behaviour of RobustStore.
