Alfresco Content Services is designed to be used predominantly in a single instance, single-tenant (ST) environment where each tenant (for example, customer, company, or organization) runs a single instance that is installed on one server or across a cluster of servers.
For some limited specific use cases and only for our OEM customers, Alfresco Content Services can be configured as a single-instance, multi-tenant environment supporting a limited set of multi-tenancy (MT) features. Multi-tenancy allows 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 Content Services instance is logically partitioned such that it will appear to each tenant that they are accessing a completely separate instance of the Alfresco repository. This can be useful for SaaS providers who make Alfresco Content Services available to their customers under an OEM agreement. Enabling multi-tenancy will restrict what repository features can be used, as described in Features not supported in a multi-tenant environment.
