CORE DEFINITION

Refers to multiple customers (tenants) sharing the same software instance and database, but their data is logically isolated. This is much cheaper than deploying a separate system for each customer (single-tenancy).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The engine of economies of scale. The core reason SaaS is profitable lies in multi-tenancy. When designing services, consider how to serve N customers with one set of resources, rather than customizing a set of resources for each customer.

Anchor fast decisions

Multi-tenancy means one software instance serves multiple customers (tenants), with logical data isolation and shared resources. The mechanism is isolation boundaries plus shared infrastructure to reduce costs.
