CLOUD COMPUTING: A COST EFFECTIVE APPROACH TO ENTERPRISE WEB APPLICATION IMPLEMENTATION (A case for cloud ERP web model)

This paper presents cloud computing in a simplified context and develops an efficient framework for enterprise web application integration in organizational models using private cloud offering. From software engineering perspective, software development life cycle (SDLC) was used to derive a process model behavior of the proposed ERP system. A comparison was made among five cloud vendors based on standard metrics that justifies our selection. This work provides the architecture for creating Clouds with market-oriented resource allocation by leveraging on technologies such as Virtualization in Google App Engine Platform. This work proposes Java, Java Eclipse 3.6 with goggle plug-in Java SDK 1.5.5 and goggle web toolkit SDK 2.4.0 for its development and implementation while the ERP system integration is done on the Google App Engine cloud platform (platform as a service-PaaS) for high performance content delivery ERP system. The cost analysis presented in this work shows that cloud offering is a better alternative for enterprise web applications.
