An efficient resource sharing technique for multi-tenant databases

Abstract

In recent times, multitenant database systems in Software as a Service (SaaS) paradigm have gained a lot of attention in academics, research and business arena. The reason being, multitenant database systems are advantageous for both SaaS providers and customers (organizations/companies referred as tenants) who uses SaaS applications. By using a single database system to store data of different tenants the providers gain operational and economic benefits. The tenants in turn get access to shared software and database at an affordable cost. However, this scenario leads to several challenges. One of them being, providing tenants dynamic access to computing resources for accessing the database, nonetheless maintaining isolation and service level agreement requirements among different tenants. The presented work proposes a dynamic resource sharing technique for accessing multitenant databases addressing the aforementioned challenge.
