Integrating Cloud Computing Services Using Enterprise Service Bus (ESB)

Abstract

Cloud computing is evolving as an important IT service platform with its benefits of cost effectiveness and global access. To become a widely adopted IT infrastructure and service platform, cloud computing has to be integrated with other systems in organizations. In academia, there is very limited study of cloud computing integration. In practice, the industry lacks a comprehensive systems integration architecture or tools that can integrate any system universally. Built upon Enterprise Service Bus (ESB) as an integration backbone, this article proposes a universal integration architecture. With this architecture, any system or service (e.g., ERP and cloud computing) can easily be integrated through the ESB without needing software redevelopment. In order to fully support the enterprise-level business operations in a heterogeneous computing environment, this architecture also introduces a rule-based business process management (BPM) engine to streamline business process management across disparate systems.

Integration of Several University E-Services in the Cloud

“…A system or service sends request messages directly to its connected service container which] in turn processes and routes the messages to a destination (requested) service container. The destination service container processes and forwards the messages to its connected destination (requested) service or system through a service adapter [10].…”

“…b) The mediation module: transforms protocol, message format, and message content between the requesting service and the service provider [10].…”

“…This module tracks activities happening in a service container and handles a variety of exceptions [10].…”

Software as a Service - Common Service Bus (SAAS-CSB)

“…This leads to the high performance of data delivery to the consumers. This application is embedded in the cloud and it has been consumed, monitored and managed by the SaaS-CSB Portal [4].…”

Managing Changes in Citizen-Centric Healthcare Service Platform using High Level Petri Net

“…There are many aspects of an ESB that fit well with the SOA model, and denying its possible usefulness would be counterproductive, but the two are not completely interdependent [4]. If we consider some of these functional elements it can be seen that items such as application adapters fall neatly into the product category, while routing and messaging are more of an architectural consideration.…”
