Multi-Tenant Authentication in 2024

Multi-tenancy is a software architecture where a single instance of an application serves multiple tenants, each operating in a self-contained environment with separate data and configurations, ensuring privacy and security. Unlike single-tenancy, where each customer has an independent software instance, multi-tenancy allows shared infrastructure, leading to cost efficiency, scalability, and simplified management. This architecture enables companies to reduce operational expenses, as demonstrated by SuperTokens, which cut AWS costs by 50% and sped up infrastructure provisioning by 94% through multi-tenancy. By centralizing resource management, multi-tenancy ensures uniform updates and maintenance, offering tailored user experiences while maintaining operational simplicity and efficiency, making it a key component of modern software systems.
