Inversion of Web Service Invocation Using Publish/Subscribe Push-Based Architecture
Among enterprise application integration solutions, Web services technologies are promising technologies to achieve the interoperability in heterogeneous environments. However, traditional Web service invocation may lead to unnecessary network traffic, long response time, and bottleneck problems at service providers. While a publish/subscribe model provides an advantage of prompt notification which can eliminate unnecessary network traffic, its achievement in interoperability is limited. By integrating Web services technologies with a publish/subscribe model, a pull-based architecture and a push-based architecture are mentioned in this paper.
