	abstract = {The approach of User-Aware Tenancy integrates the high configurability of multi-tenant applications with the flexibility and the functional variability of Rich-Variant Component use. Multi-tenancy concept consists in sharing instances among a large group of customers, called tenants. Multi-tenancy is a tool to exploit economies of scale widely promoted by Software as a Service (SaaS) models. However, the ability of a SaaS application to be adapted to individual tenant{\textquoteright}s needs seem to be a major requirement. Thus, our approach focuses on more flexibility and more reusability for Multi-tenant SaaS application using the multiview notion of Rich-Variant Components. The approach consists in a user-aware tenancy for SaaS. In this paper, we provide an application of an algorithm deriving the necessary instances of Rich-Variant Components building the application in a scalable and performing manner. The algorithm is based on fundamental concepts from the graph theory, and is accompanied by a reduced school management application as an illustrating example.},

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.},

	abstract = {Software-as-a-Service (SaaS) is a new delivery model, that involves providing applications to the customer on demand over the Internet. SaaS promotes multi-tenancy as a tool to exploit economies of scale. However, the flexibility of an application to be adapted to individual tenant{\textquoteright}s needs is a major requirement. Thus, we initiate in this paper to an approach proposing a more flexible and reusable SaaS system for multitenancy. This approach consist on integrating a functional variability using Rich-Variant Components with a deployment variability enabling the customers to choose with which others tenants they want or don{\textquoteright}t want to share instances. The approach presented enables exploiting the economies of scale while avoiding the problem of customers{\textquoteright} hesitation about sharing with other tenants.},
