ECB: Enterprise Cloud Bus Based on WS-Notification and Cloud Queue Model

With the rapid development of Service-Oriented Architecture (SOA), more and more enterprise applications are built on the Enterprise Services Bus (ESB). However, ESB would not be able to deal with the exchange of data among multiple ESBs. In this paper, we propose an Enterprise Cloud Bus (ECB) framework that combines the WS-Notification with cloud computing. On the basis of WS-Notification specification and cloud queue model, we design and implement the Subscribe Request Queue cloud service model that supports real-time communication among distributed ESB, and supports running non-Service components or composition services deployed on distributed ESB or in different business process. On the basis of cloud platform, our framework shows better scalability and reliability.
