**Understanding the Modular Monolith Architecture: A Balanced Approach**

A **Modular Monolith** is an architectural style that structures your application into distinct, well-defined modules within a single codebase. It combines the simplicity and performance of a monolithic design with the maintainability benefits of modularization. Each module is responsible for a specific domain, making it easier to develop, test, and maintain. However, as the application grows, scaling and managing dependencies can become more challenging compared to microservices.

**Pros:**

- **Maintainability:** Clear module boundaries improve code organization.

- **Performance:** Fewer inter-service communications lead to better performance.

- **Deployment:** Simplified deployment process since it's a single application.

**Cons:**

- **Scalability:** Scaling becomes harder as the app grows.

- **Complexity:** Managing module dependencies can get tricky over time.
