Multi-tenancy Multi-target (MT2): An extension to cloud multi-tenant architectures for multi-service support in SaaS enterprise information systems

Abstract

This thesis studies cloud multi-tenant architectures in depth, and explicitly define detailed reference models both for the AMTs and its critical data level. On the basis of these models we propose a novel extension to the traditional AMTs that allow multiple functionalities to be deployed selectively using one single software instance. This extension aims to foster reusability, again reduce the prices and decrease complexity in software use. Moreover, the approach advocates for agile architectures, since it provides a support for the agility in development, minimizing the effort and shortening the time-to-market. Lastly, in order to demonstrate the applicability of the proposal we present Globalgest, a commercial software application with underlying extended MTA architecture. Globalgest can deploy selectively multiple functionalities and it is currently serving more than 40 companies belonging to different sectors.
