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.

Architecture Ratings:
