Describe the advantages and disadvantages of microservice architecture.

Advantages:

• Scalability: Each service can be scaled independently.
• Resilience: The failure of one service does not affect the operation of others.
• Technology flexibility: Different services can use different languages and frameworks.
• Faster development and deployment: Small teams can work on individual services in parallel.
• Ease of understanding: Each service has a limited scope of responsibility.
• Gradual update capability: You can update and deploy individual services without stopping the entire system.

Disadvantages:

• Management complexity: Distributed systems are more difficult to monitor, debug, and manage.
• Operational costs: The number of network calls and data serialization/deserialization increases.
• Testing complexity: Integration testing between services requires more effort.
• Need for distributed tracing and logging: To understand the flow of requests across multiple services.
• Potential redundancy: Some functions, such as authentication or logging, may be duplicated across different services.
• Team organization complexity: Clear boundaries of responsibility for services are required.
