Abstract

Service-Oriented Architecture (SOA) using Web services is considered as the state-of-the-art for distributed systems integration. As Web services start to be deployed across enterprise boundaries and for collaborative e-business scenarios, higher quality of service (QoS) and reliable inter-application messaging becomes a critical issue to ensure guaranteed and ordered delivery even in the case of system or network failures or temporary service outage. To address these requirements, we propose wsBus, a lightweight service-oriented middleware for dependable Web services interactions using broker pattern. We discuss the system architecture and features then report our experiences in building wsBus as well as some initial performance results.
