Explain the concept of microservices architecture and its main advantages

Microservice architecture is an approach to building software systems where the application is broken into many small, independent services, each responsible for its own business function and interacting with others through well-defined APIs.

Main advantages:

• Scalability: each service can be scaled independently based on load.
• Development flexibility: different teams can work in parallel on different services using suitable technologies.
• Resilience: failure of one microservice does not bring down the entire application.
• Fast deployment: individual services can be updated without stopping the whole system.
• Simplified maintenance: smaller codebases in each service make understanding and testing easier.
