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

Microservice architecture divides the system into independent services, each responsible for its own business function.

Advantages:

• Scalability: only the services experiencing load need to be scaled.
• Independence in development and deployment: teams can work in parallel.
• Resilience: failure of one service does not lead to the collapse of the entire system.
• Use of different technologies for different services.

Disadvantages:

• Management complexity: orchestration and monitoring of multiple services are required.
• Difficulties with transactions and data consistency.
• Increased infrastructure requirements (network, security).
• Possible delays due to inter-service interactions.

Example: in an online store, separate microservices can be responsible for the product catalog, cart, payment, and delivery, allowing each to be developed and scaled independently.
