Abstract: In SaaS, most tenants rely on the service provider for data maintenance and computation. As tenants no longer possess their application and data locally, it is of critical importance for the tenants to ensure that their data are being cor-rectly stored and maintained. However

Abstract. Cloud computing promotes economies of scale by sharing soft-ware and hardware resources across multiple tenants. To date, there has been relatively little research on how MDE can best support multi-tenant cloud ap-plications, where there is a need to separate the logic and data

Keywords-Software architecture; Software quality; Software performance; Software maintenance Abstract—A multi-tenant software application is a special type of highly scalable, hosted software, in which the ap-plication and its infrastructure are shared among multiple tenants to save development

Abstract: Multi-tenant software applications serve different organizations from a sin-gle instance and help to save development, maintenance, and administration costs. The architectural concepts of these applications and their relation to emerging platform-as-a-service (PaaS) environments are still

Multi-tenancy is a relatively new software architecture principle in the realm of the Software as a Service (SaaS) business model. It allows to make full use of the economy of scale, as multiple customers – “tenants ” – share the same application and database instance. All the while, the tenants

application across many tenants, multi-tenancy attempts to replace many small application instances with one or few large instances thus bringing down the overall cost of IT infrastructure. In this paper, we present an architecture for achieving multi-tenancy at the SOA level, which enables users to run

a more single-tenant approach. The appropriate level of resource sharing is crucial for a software provider, because it defines an architectural decision. However, there is insufficient knowledge and understanding to determine the most suitable multi-tenant architecture for the software application

The paper starts with a generic discussion on the cloud application services and security concerns then expands the concepts with 3 main data management approaches of multi-tenant data management. After that paper describes reference architecture including standard cloud computing taxonomy for meta
