Abstract—The information technology industry designs various e-services based on the fast delivery, powerful computing and large storage capacity of cloud computing systems. Specifically, the service provider develops e-service markets within a cloud computing environment with which to provide the e-services. The use of information technology, insofar as helping people obtain reasonable e-service, provides challenges to innovative service providers. In this work, we propose an adaptive e-service for linking users and the cloud services. Our work is based on user profile, specifically, on a role-based access control model with which to identify the user and assign a specific role. A user with a specific role is then authorized to access the various eservices in the cloud computing environment. Then, the utility function and multi-criteria decision analysis model are deployed to optimize the e-service selection with regard to various cloud services. Our aim is that the proposed adaptive e-service will be able to assist people in obtaining eservices in cloud environments.

Index Terms—Adaptive e-service; role-base access control; utility function, multi-criteria decision analysis.
