Multi-Tenancy
Multi-Tenancy (MT) is a software architecture, where a single instance of the software runs on a software-as-a-service (SaaS) vendor's server, while serving multiple client organizations (tenants). MT is contrasted with a multi-instance architecture, where separate software instances (or hardware systems) are set up for different client organizations. With a multi-tenant architecture, a software application is designed to virtually partition its data and configuration, so that each client organization works with a customized virtual application instance.
Alfresco ECM can be configured as a true single-instance multi-tenant environment. This enables multiple independent tenants to be hosted on a single instance, which can be installed, either on a single server or across a cluster of servers. The Alfresco instance is logically partitioned in such a way that it will appear to each tenant as if they are accessing a completely separate instance of Alfresco.
