What are the main principles of microservice architecture?

Principles of microservice architecture:

• Modularity and independence: each microservice is responsible for a specific business function and can be developed, deployed, and scaled independently.
• Data isolation: microservices have their own databases or storage, reducing coupling and increasing resilience.
• Lightweight communication: interaction between microservices occurs through lightweight protocols (e.g., HTTP/REST, gRPC, messages).
• Deployment autonomy: the ability to update and deploy services without stopping the entire system.
• Fault tolerance: failure of one microservice should not lead to the collapse of the entire system.
• Organization by business domains: the structure of microservices reflects the business domain, facilitating understanding and development.

These principles help create scalable, flexible, and maintainable systems.
