Thus, it is suggested to extend firstly the service oriented architecture (SOA) into an architecture called MV-SOA by adding two components, the Multiview service generator, whose role is to transform the classic service into Multiview service, and the data base, this component seeks to stock all of consumer service information. It is also suggested to combine the computing cloud and Multiview Service Oriented Architecture MVSOA. To reach such combination, the MVSOA architecture was taken and we added to the client-side a private cloud in SaaS and DaaS.

INTRODUCTION SOA (Service Oriented Architecture) is often deemed equivalent with technology, but it is actually the principles of architecture. Indeed, the concept of SOA refers to a new way to integrate and manipulate different bricks and application components of an information system (accounting, customer relationship management, production, etc.) and to manage the links that maintain them. This approach is based on the reorganization of applications into functional units called services. Prior to the emergence of SOA, the services of a company were developed in a monolithic application; in other words, they were deployed on a central server. Gradually, the distributed model was set up while enabling more flexibility in the management of the information system. Indeed, the corporate information systems consist of applications and data components regarded as their legacies. Through the merger of the groups and the development of technologies, such legacies became heterogeneous and tend to specialize in business through services. Then an overall view of a company's information system can be within reach. Thus, a new concept has emerged using the distributed models. The latter has been conceptualized by the Gartner Group, the SOA is attempting to impose itself by making them more flexible and reusable. SOA is based on standards and it can operate in heterogeneous environments. Its main goal is to improve interoperability between systems without creating high stress [1]. Indeed, the
