Abstract
Software as a service (SaaS) is a promising service model of cloud computing. Its key characteristic is the ability for clients to use a software application on a pay-as-you-go subscription basis. To be economically sustainable, a SaaS application must be multitenant. However, it is generally agreed that designing a multitenant enterprise application in SaaS environments is a non-trival task. In this work, we propose an integrated service middleware that addresses cross-cutting concerns when developing and deploying multitenant enterprise SaaS applications. To verify the feasibility of our approach, a sample SaaS application have been implemented on the proposed middleware. Also, two tenant-specific virtual applications are constructed to demonstrate multi-tenancy. Finally, a series of performance evaluations are conducted to assess the overheads of making an enterprise application multitenant enabled.
