What Are The Fundamentals Of Microservices Design?
Câu trả lời
The fundamentals of microservices design revolve around several key principles and best practices that ensure the architecture is scalable, maintainable, and resilient. Here are the core fundamentals:
1. Single Responsibility Principle (SRP)
Each microservice should focus on a single business capability or function. This principle ensures that services are highly cohesive and can be developed, deployed, and scaled independently[2][3][10].
2. Loose Coupling
Microservices should be loosely coupled, meaning that changes in one service should not require changes in another. This independence allows for easier updates and maintenance[10][14].
3. Autonomous Services
Each microservice should be self-contained and operate independently. This includes having its own database and business logic, which helps in achieving decentralization and reducing dependencies[3][10][13].
4. API-Based Communication
Microservices communicate with each other through well-defined APIs, typically using REST or gRPC. This approach ensures that services can interact regardless of the underlying technology stack[3][14][19].
5. Scalability
Microservices should be designed to scale independently. This means that each service can be scaled up or down based on demand without affecting other services[3][14].
6. Resilience and Fault Tolerance
Microservices should be designed to handle failures gracefully. Techniques like circuit breakers, retries, and bulkheads can help in isolating failures and preventing them from cascading through the system[4][6][18].
7. Continuous Delivery and Deployment
Microservices architecture supports continuous integration and continuous delivery (CI/CD) practices. This allows for frequent and reliable releases of software, enhancing agility and reducing time-to-market[4][14].
8. Decentralized Data Management
Each microservice should manage its own data, which helps in maintaining data consistency and integrity. This approach also allows for the use of different databases and storage technologies as needed[10][18].
9. Service Discovery
In a dynamic microservices environment, services need to discover each other. Service discovery mechanisms help in locating services and managing their instances, ensuring seamless communication[5...
