Towards a high configurable SaaS: To deploy and bind auser-aware tenancy of the SaaS

User-aware tenancy approach integrates the flexibility of the Rich-Variant Component with the high configurability of multi-tenant applications. Multi-tenancy is the notion of sharing instances among a large group of customers, called tenants. Multi-tenancy is a key enabler to exploit economies of scale for Software as a Service (SaaS) approaches. However, the ability of a SaaS application to be adapted to individual tenant's needs seem to be a major requirement. Thus, our approach proposes a more flexible and reusable SaaS system for Multi-tenant SaaS application using Rich-Variant Components. The approach consists in a user-aware tenancy for SaaS environments. In this paper, an algorithm is established to derive the necessary instances of Rich-Variant Components building the application and access to them in a scalable and performing manner. The algorithm is based on fundamental concepts from the graph theory. Copyright © 2015 SCITEPRESS - Science and Technology Publications.
