Multi-tenancy
Multi-tenancy is a software architecture pattern where a single instance of an application serves multiple customers (tenants), with data and configuration isolated for each tenant. It allows efficient resource sharing while maintaining security and privacy between tenants, commonly used in cloud-based SaaS (Software as a Service) applications. This approach reduces operational costs and simplifies maintenance compared to single-tenant deployments.
Developers should learn multi-tenancy when building scalable SaaS applications, cloud services, or enterprise software that needs to serve multiple organizations or user groups from a shared infrastructure. It's essential for optimizing resource utilization, reducing hosting costs, and enabling rapid deployment of updates across all tenants. Use cases include CRM systems, collaboration tools, and e-commerce platforms where data isolation and customization per client are critical.
