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

Monolithic architecture is an approach where all components of an application are combined into a single codebase and deployed as a whole.

Advantages:

• Simplicity of development and deployment in the initial stages.
• Easier to debug and test, as everything is in one place.
• No need for complex infrastructure for interaction between services.

Disadvantages:

• Difficulty in scaling individual parts of the application.
• As the codebase grows, maintenance and understanding become more complex.
• Changing one part can affect the entire system, increasing the risk of errors.
• Difficult to implement new technologies in individual modules.

Thus, monolithic architecture is suitable for small projects or startups, but as the system grows, many switch to microservices.
