What are the advantages and disadvantages characteristic of microservices architecture?

A microservices architecture is an approach to building applications as a set of small, autonomous services, each responsible for its own business logic.

Advantages:

• Scalability: individual services can be scaled as needed.
• Independent development and deployment: teams can work in parallel.
• Resilience: failure of one service does not bring down the entire application.
• Flexibility in choosing technologies for each service.

Disadvantages:

• Management complexity: orchestration, monitoring, and logging of many services are required.
• Network delays and communication issues between services.
• Difficulties with transactions and data consistency.
• Increased infrastructure and automation requirements.

For QA, it is important to consider integration testing between services, load testing, and monitoring.
