Multi-tenancy

Multi-tenancy is a common pattern in web application development, for serving up to multiple “tenants” customised versions of the same application.

All of the work on software product lines implementation applies to multi-tenancy. Most multi-tenant sites can be viewed as software product lines, with the individual product being defined at load-time.
