Architecting Web Services Applications for Improving Availability

  • Conference paper
Architecting Dependable Systems III

Part of the book series: Lecture Notes in Computer Science ((LNPSE,volume 3549))

Abstract

In this paper, we address the problem of improving the availability and correctness of Web Services. An architectural approach is proposed that incorporates fault-tolerant techniques, such as, self-checking, comparison, and dynamic reconfiguration. The first two techniques are associated with the detection and handling of faults at the component level, while the latter is associated with the system. To demonstrate its applicability, a distributed application was designed and implemented that addresses the problem of obtaining dependable stock quotes from the Web. The system was implemented using Web Services core technologies, and preliminary measurements confirmed the improved availability of the whole application.
