# 2.1 - Fortress Multitenancy
## Multitenancy Defined
(From Wikipedia)
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 is contrasted with a multi-instance architecture where separate software instances (or hardware systems) are set up for 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 instance.
Multitenancy is also regarded as one of the essential attributes of cloud computing.[1]
## After Fortress
Multi-tenancy allows many clients to share the same ldap infrastructure thus enjoy increased operational efficiency.
