What is Multi-Tenancy / Tenant?

Multi-tenancy is a setup where one software system serves many customers, called tenants. Each tenant’s data, users, and settings stay separate, even though they share the same platform. In identity management, multi-tenancy lets businesses manage different units, partners, or customer groups from one place. Each tenant works like its own space with unique users, branding, and access rules. A tenant is simply one of these isolated environments within a multi-tenant system.
