The concept of multi-tenancy is a single instance of software that runs on a server and serves multiple client organizations. A software application is designed with a multitenant architecture to virtually divide the data and configuration where each client organization can customize its own virtual application instance. This project aims to demonstrate the conversion of single-tenant applications to multi-tenant applications. The project is applicable for every open-source (java) single-tenant application that runs overcloud. As a part of this project, an eclipse plug-in is developed that will assist users to migrate the code and make necessary changes.
