Towards Services-Based Enterprise Architecture for Cloud Computing-Opened Information Systems

With the development of cloud computing technologies and the multiplication of enterprise architecture reference frameworks, the industrials are encouraged to take into account the new concepts of cloud service in the evolution of their information system strategies. The present paper starts by presenting background concepts and the state of the art of the enterprise architecture, in order to propose a maturity model that helps enterprises to build and evaluate a functional component of their Information System architecture and allow them to qualify its externalization to the Cloud Computing as well as its monitoring.
