Dependability should be considered throughout the phases of the SOA life cycle. This article proposes the application of a service level management approach to address dependability and presents dependability-related activities for every stage (Model, Assemble, Deploy, and Manage) of the SOA life cycle. Furthermore, we describe the concepts and the formalisms that are behind these activities. Following...
This paper evaluates replication possibilities for Web services at the operating system level and how they affect Web service performance. This is done in the context of architectural translucency - an approach that defines layers in a service-oriented architecture and states that similar measures have different implications on nonfunctional properties when applied at different layers in different...
Service-oriented architecture (SOA) is a popular design paradigm for distributed systems today but the high adaptivity and complexity of SOA implementations may also introduce additional sources of faults. We first describe typical steps in SOA to understand possible faults. Then, we provide a corresponding fault taxonomy according to the process of service invocation. Finally, we present possible...
