| Description | Software-as-a-Service (SaaS) applications are multi-tenant software applications that are delivered as highly config-urable web services to individual customers, which are called tenants in this context. For reasons of complexity manage-ment and to lower maintenance cost, SaaS providers main-tain and deploy a single version of the application code for all tenants. As a result, however, custom-made extensions for individual tenants cannot be efficiently integrated and man-aged. In this paper we show that by using a context-oriented programming model, cross-tier tenant-specific software vari-ations can be easily integrated into the single-version appli-cation code base. Moreover, the selection of which variations to execute can be configured on a per tenant basis. Con-cretely, we provide a technical case study based on Google App Engine (GAE), a cloud platform for building multi-tenant web applications. We contribute by showing: (a) how ContextJ, a context-oriented programming (COP) lan-guage, can be used with GAE, (b) the increase in flexibil-ity and customizability of tenant-specific software variations using ContextJ as compared to Google’s dependency injec-tion framework Guice, and (c) that the performance of using ContextJ is comparable to Guice. Based on these observa-tions, we come to the conclusion that COP can be helpful for providing software variations in SaaS. |
