Shared Tenant Model
The Shared Tenant Model is a software architecture pattern used in multi-tenant applications where multiple customers (tenants) share a single instance of the application and its underlying infrastructure, including databases and resources. It contrasts with isolated tenant models by pooling resources to improve efficiency and reduce costs, while implementing logical separation through tenant identifiers and access controls. This model is common in SaaS (Software-as-a-Service) platforms to scale services economically.
Developers should learn and use the Shared Tenant Model when building scalable SaaS applications that need to serve many customers with similar requirements, as it optimizes resource utilization and lowers operational overhead compared to per-tenant isolation. It is particularly suitable for scenarios where tenants have moderate data privacy needs and the application can enforce robust security measures, such as in CRM or project management tools. However, it requires careful design to prevent data leakage and ensure performance isolation between tenants.
