MehrTenancy

MehrTenancy refers to a software architecture where a single instance of an application serves multiple distinct customers, referred to as tenants. Each tenant operates independently, with their data and configurations isolated from other tenants. This approach is commonly employed in Software as a Service (SaaS) applications.

The core principle of MehrTenancy is resource sharing. Instead of deploying and managing a separate application instance for each customer, all tenants utilize the same underlying software and infrastructure. This leads to significant cost efficiencies in terms of hardware, maintenance, and operational overhead.

There are several models for implementing MehrTenancy, including separate databases, shared databases with schema separation, and shared databases with shared schemas. The choice of model impacts the level of isolation, scalability, and cost-effectiveness.

Benefits of MehrTenancy include reduced costs, simplified maintenance and updates, and faster deployment. However, it also presents challenges related to security, data isolation, performance customization, and the need for robust multi-tenant management capabilities. Careful design and implementation are crucial to ensure that tenants remain isolated and that the system performs optimally under varying loads.
