Exploring the performance of authentication mechanism in integrated cloud services environment with CSP

Most of the current cloud computing platforms are integrated massive cloud services, which aim to provision abundant computing and storing services to end users. Web portal works as a manager of a large volume of cloud services and end users in cloud computing environment. Nevertheless, a major hurdle of formal adoption of web portal for cloud services is performance that is not always investigated in the past, and we believe there is still a lot of room to improve performance in web portal without affecting the integrated cloud services environment. This paper proposes a cloud service integration architecture with Cloud Service Portal (CSP) and Cloud Service Bus (CSB) in hybrid cloud. We present a four-layer CSP architecture and define a run-time data model with some operators in CSP. Three run-time data storage patterns including file pattern, database pattern and memory pattern are given by CSP to explore its performance. We improve an authentication mechanism from OAuth 2.0 and use to our integration architecture. Finally, we conclude that memory storage pattern is more cost effective and has fast response time as compare to others two patterns in CSP login and authority services. It means, the proposed architecture has good performance to be used in cloud service authentication. © 2016 Journal of Communications.
