Service composition is an important means for integrating the individual Web services for creating new value added systems. However, Web service exists in the heterogeneous environments on the Internet, thus it is challenging to guarantee the reliability of composite service evolution. To address this problem, we propose the approach to modeling and analyzing the reliability of composite service evolution...
Service composition is an important means for integrating the individual Web services for creating new value added systems. However, Web service runs in the heterogeneous environments on the Internet, it is difficult to guarantee the reliability of service composition. To address this problem, we propose a systematic method to model and analyze reliability for service composition. First, we present...
Service composition is an important mean for integrating the individual Web services to create new value added systems that satisfy complex requirements. However, it is challenging to guarantee the reliability of service composition in a distributed, dynamic and complex environment. This paper proposes an approach to constructing the reliable service composition. The underlying formalism is Petri...
Cloud computing has attracted much interest recently from both industry and academic. More and more Internet applications are moving to the cloud environment. However, fault detection technique in cloud application is a crucial issue. This issue is especially difficult since cloud computing relies by nature on a highly dynamic environment. In this paper, we propose a model based Byzantine fault detection...
Service composition is an effective way to achieve value-added service, which has found wide application in software system. Fault handling is critical to achieve high reliability for these applications. However, the existing service composition methods seldom consider services' fault handling, which results in high risk of runtime failure. This paper proposes a formal aspect-oriented approach to...
Reliability is a key issue of the service-oriented architecture (SOA) that is widely employed in distributed systems such as e-commerce and e-government. Redundancy based technologies are usually employed for building reliable service composition on top of unreliable Web services. This paper proposes a strategy for modeling and analyzing fault tolerant service composition. The strategy consists of...
As a way to compose independent services together to fulfill a function, service composition is an important means for flexible and rapid information integration of complex distribution application in open and heterogeneous environment. Because the participating services may be failure or unavailable, how to guarantee the quality of service composition has become a challenging problem. A service composition...
