Shared Tenancy
Shared tenancy is a software architecture pattern where multiple customers or users share a single instance of an application and its underlying infrastructure, with logical separation of data and configuration. It is commonly used in Software-as-a-Service (SaaS) applications to achieve cost efficiency and scalability by pooling resources. This contrasts with single-tenancy, where each customer has a dedicated instance.
Developers should learn shared tenancy when building scalable SaaS products, as it reduces operational costs and simplifies maintenance compared to single-tenancy setups. It is particularly useful for startups and large-scale applications where resource optimization and rapid deployment are critical, such as in cloud-based CRM, collaboration tools, or e-commerce platforms.
