“…Moreover, UI configuration can be either for adding/deleting/editing components on the forms or adding/deleting/editing forms in the UI [11], [21]. In SaaS ERP systems, UI configuration can be embedded into the front-end configuration [17]. However, the UI configuration could be considered complex in SaaS systems, hence each tenant vary in their UI requirements [24].…”

Abstract-Enterprise resource planning (ERP) systems are the organizations tickets to the global market. Thus, organizations can manage and coordinate all functions, processes, resources and data from different departments by a single software. However, many organizations consider the cost of traditional ERP is expensive and look for alternative affordable solutions within their budget. One of these alternative solutions is providing ERP over a software as a service (SaaS) model. A key feature of any SaaS system is the multi-tenancy architecture where multiple customers (tenants) share the system software. However, the SaaS developers accommodate each tenant's unique requirements by allowing tenant-level customization or configuration. While customization requires source code changes and in most cases a programming experience, the configuration process allows user to change many features within a pre-defined scope in an easy and controlled manner. Although literature provides many techniques to accomplish the configuration process in different SaaS systems, the nature and complexity of SaaS ERP are merely described in previous researches. Thus, this research is built on strong knowledge regarding the configuration in SaaS to define specifically the configuration borders in SaaS ERP and to design a configuration service with the consideration of the different configuration aspects.Index Terms-Configuration, software as a service, multi-tenancy, ERP.

A Middleware Layer for Flexible and Cost-Efficient Multi-tenant Applications

Application-level multi-tenancy is an architectural design principle for Software-as-a-Service applications to enable the hosting of multiple customers (or tenants) by a single application instance. Despite the operational cost and maintenance benefits of application-level multitenancy, the current middleware component models for multi-tenant application design are inflexible with respect to providing different software variations to different customers. In this paper we show that this limitation can be solved by a multitenancy support layer that combines dependency injection with middleware support for tenant data isolation. Dependency injection enables injecting different software variations on a per tenant basis, while dedicated middleware support facilitates the separation of data and configuration metadata between tenants. We implemented a prototype on top of Google App Engine and we evaluated by means of a case study that the improved flexibility of our approach has little impact on operational costs and upfront application engineering costs.
