Theoretical and Pragmatic Cases of a Rich-Variant Approach for a User-Aware Multi-Tenant SaaS Applications

Abstract

Software as a Service cloud computing model favorites the Multi-Tenancy as a key factor to exploit economies of scale. However Multi-Tenancy present several disadvantages. Therein, our approach comes to optimize instances assigned to multi-tenants with a solution using rich-variant components while ensuring more economies of scale and avoiding tenants hesitation to share resources. The paper present the theoretical and pragmatic cases of a user-aware multi-tenancy SaaS approach focused on graph-based algorithms. The theoretical case consists in having a set of tenants while the pragmatic case consists in adding a new tenants to a set of tenants.
