Answer from AI
Microservices architecture is an approach to software development where an application is built as a collection of small, autonomous services that interact with each other.
Key characteristics:
- Monadicity: Each service is responsible for a specific business function and is developed, deployed, and scaled independently.
- Loose coupling: Services interact through lightweight mechanisms (e.g., HTTP/REST, gRPC, asynchronous messages). Internal implementation details are hidden.
- Technological independence: Different services can be written in different programming languages and use different databases suitable for their specific tasks.
- Decentralized data management: Each service has its own database, which allows better data management but requires synchronization or compensation mechanisms in distributed transactions.
- Autonomous deployment: Services can be deployed independently, speeding up the delivery of new features and fixes.
Advantages:
- Scalability of individual services.
- Flexibility in technology choices.
- Resilience to failures (failure of one service does not affect others).
- Faster development and deployment.
- Simpler code maintenance (smaller codebases).
Disadvantages:
- Complexity of managing a distributed system.
- Network load due to inter-service communication.
- Debugging difficulties.
- Infrastructure requirements for deployment and monitoring (e.g., Docker, Kubernetes).
- Challenges with distributed transactions.
