What are the advantages and disadvantages of using microservice architecture in systems?

Advantages of microservices architecture:

• Scalability: each service can be scaled independently.
• Development flexibility: teams can work on different services in parallel, using different technologies.
• Resilience: failure of one microservice does not lead to the collapse of the entire system.
• Rapid deployment and updating of individual components.

Disadvantages:

• Management complexity: orchestration and monitoring of multiple services are required.
• Increased infrastructure and network interaction requirements.
• Difficulties in ensuring data integrity and transactions.
• Possible delays due to inter-service communication.

Example: in a microservices project, the authentication service can be scaled separately without affecting other parts of the application.
