What are the advantages and disadvantages of monolithic architecture compared to microservices architecture?

Monolithic Architecture:

Advantages:

• Simplicity of development and deployment in the initial stages.
• Fewer complexities with inter-module interactions.
• Convenience of debugging and testing, as everything is in one application.

Disadvantages:

• Difficulty in scaling individual parts of the application.
• When changing one part, the entire monolith needs to be rebuilt and redeployed.
• Complexity of maintaining and introducing new technologies in individual modules.

Microservices Architecture:

Advantages:

• Scalability of individual services independently of each other.
• Ability to use different technologies for different services.
• Improved resilience: failure of one service does not lead to the failure of the entire application.

Disadvantages:

• Complexity of organizing interaction between services (network, API).
• More complex testing and debugging of a distributed system.
• Need for infrastructure setup for orchestration and monitoring (e.g., Kubernetes).

The choice of architecture depends on the project requirements, team, and resources.
