-#### 1. **Single Instance Deployment (Minimal Setup)**
-
-**Use Case**: Suitable for development or testing environments.
-
-- A single mediator instance handles all requests and routing.
-- Simplifies deployment but lacks fault tolerance and scalability.
-
-**Advantages**:
-- Minimal resource usage.
-- Easy to configure and maintain.
-
-**Disadvantages**:
-- No fault tolerance: if the mediator fails, the service becomes unavailable.
-- Limited scalability.
