摘要：The single-instance deployment mode can't meet the needs of the increasing user access, and multiple-instance deployment is a feasible scheme to improve the scalability of the service system. The traditional reliability analysis methods are aimed at the single-instance deployment and they cannot be used to analyze the reliability of the service system of multi-instance deployment. To address this problem a new approach is proposed in this paper to analyze the reliability of service that a services system provided in the case of multiple-instance deployment. This approach extends the traditional user-oriented system reliability analysis method, adopting a vector representing the reliabilities of the multiple instances of a component service to settle down the problem. To bring this method to fruition, a prototype framework is constructed and realized in Java, and a case study demonstrates this approach.
