Introduction
Multitenancy refers to the architectural principle whereby a single instance of software runs on a software-as-a-service (SaaS) vendor’s servers, whilst serving multiple client organizations (tenants). This is in contrast to multi-instance architecture where separate software instance or hardware systems are set up for different client organizations. in other words, under a multitenant architecture, applications are required to virtually partition data and configuration so that each client organization works with a customized virtual application instance. Customization typically includes aspects like user interface branding, access control, data and configuration, workflow, etc
