## 1. In a microservices architecture, what is the main advantage of separating a monolithic Django application into multiple independent services?

**Answer**

Separating into microservices allows deploying and scaling each service independently based on its specific needs. A high-load service can be replicated without affecting others, optimizing resource usage. Additionally, teams can work autonomously on different services with independent deployment cycles.

## 2. What is the main role of an API Gateway in a microservices architecture with Django?

**Answer**

The API Gateway acts as a single entry point for all client requests. It routes requests to appropriate services, handles centralized authentication, rate limiting, and can aggregate responses from multiple services. This simplifies the client interface and offloads individual services from these cross-cutting concerns.

## 3. What is service discovery in a microservices ecosystem?

**Answer**

Service discovery is a mechanism allowing services to dynamically locate each other without knowing their IP addresses or ports in advance. Tools like Consul, Eureka or Kubernetes DNS maintain a registry of available services. When a service starts, it registers itself, and others can discover it automatically.
