Question: Please explain how you approach designing a scalable and maintainable software architecture for a large-scale enterprise application.

Answer: We should design different microservices that can communicate with each other. This way, each microservice can be maintained separately and scaled when needed. Each microservice should follow the principle of separation of concerns, meaning we organize the code into different layers like core domain, business logic, services, and data storage.

When building these microservices, we also follow important design rules like:

• DRY (Don’t Repeat Yourself) to avoid duplicating code,
• KISS (Keep It Simple, Stupid) to make the design simple, and
• SOLID to ensure the system is flexible and easy to maintain.

Additionally, having strong test automation is important because it makes the microservices easier to maintain over time.
