Analyzing the role of interfaces in enterprise service bus: A middleware epitome for service-oriented systems

The modern" era of computing is designed around service-oriented systems which integrate multiple services to deliver sophisticated services through well-known interfaces. It could efficiently be done by using features of Service-Oriented Architecture (SOA) like reusability, scalability and interoperability. SOA is an adaptive and flexible enough to acquire changes for dynamic environments but it is noted that it is limited with remote and distributed access to services in complex systems where interfaces are not recognized as common medium. This could be strengthened with adopting framework which not only meet such requirements but also provide varieties of interface between multiple services from different domains of applications. Enterprise Service Bus (ESB) is a middleware distributed kind of framework that extends the features of SOA systems and supports the deployment of end-to-end services through well-defined 'interface' called connector. The main contribution for this paper is building a deriving mathematical formulation that provides relationship with successfully chance for getting interface during interaction between multiple services. This paper also analysis and investigate the comparison for non-ESB and ESB as interface usage in facilitating services over networks. (C) 2017 Elsevier B.V. All rights reserved.
