Single Tenancy
Single tenancy is a software architecture model where each customer or tenant has a dedicated, isolated instance of the application and its underlying infrastructure, such as separate databases, servers, or virtual machines. This contrasts with multi-tenancy, where multiple tenants share the same resources. It is commonly used in enterprise software, legacy systems, and scenarios requiring high security or customization.
Developers should use single tenancy when building applications that require strict data isolation, compliance with regulations like GDPR or HIPAA, or extensive customization for individual clients. It is ideal for high-security environments, such as government or financial systems, where tenant data must be physically or logically separated to prevent cross-tenant access or breaches.
