Multi - tenant Architecture
Multitenancy refers to a principle in software architecture where a single instance of the software runs on a server, serving multiple client-organizations (tenants).
Multitenancy contrasts with multi-instance architectures where separate software instances (or hardware systems) operate on behalf of different client organizations.
With a multitenant architecture, a software application is designed to virtually partition its data and configuration, and each client organization works with a customized virtual application.
Multitenancy is the fundamental technology that clouds use to share IT resources cost-efficiently and
securely.
Just like in an apartment building—in which many tenants cost-efficiently share the common
infrastructure of the building but have walls and doors that give them privacy from other tenants—a cloud
uses multitenancy technology to share IT resources securely among multiple applications and tenants
(businesses, organizations, etc.) that use the cloud.
Some clouds use virtualization-based architectures to isolate tenants, others use custom software architectures to get the job done.
The multitenant design of a cloud service can have a dramatic impact on the application delivery and
productivity of an IT organization, yet most CIOs, CTOs, system architects, and developers who use clouds don’t give it a second thought because it’s all magic that transparently happens behind the scenes.

These bundles, called editions, all share the same look and feel, but they vary by feature, functionality, and pricing.
