What are the advantages and disadvantages of using monolithic architecture in system development?

Advantages of monolithic architecture:

• Simplicity of development and deployment — all code in one application.
• Easier to debug and test, as all components are together.
• Less overhead for communication between services.
• Suitable for small and medium projects.

Disadvantages:

• Scalability challenges — the entire application scales as a whole.
• Difficulties in adopting new technologies or updating individual parts.
• As the codebase grows, maintenance and understanding become more complex.
• An error in one module can affect the entire application.

Monoliths are well-suited for startups and small projects, but as the system grows, many transition to microservices.
