Multi-tenant architecture, commonly referred to as multitenancy, is a software architecture in which multiple single instances of software run on a single physical server. The server then serves multiple tenants.“Tenants” is a term for a group of users or software applications that all share access to the hardware through the underlying software. Multiple tenants on a server all share the memory, which is dynamically allocated and cleaned up as needed. They also share access to system resources, such as the network controller.This is the opposite of single-tenancy, in which the server runs one instance of the operating system and one application. This one application could be something simple like file and print apps, complex like Web or application servers, or mission-critical, such as a database. ANDY PATRIZIO READ MORE
