The combination of Docker containers and microservices architecture is the mainstream approach for modern application deployment. Advantages: 1) containerization ensures microservice environment consistency; 2) independent deployment and scaling of each microservice; 3) resource isolation improves system stability; 4) fast startup and shutdown supports elastic scaling; 5) simplifies CI/CD workflows; 6) facilitates service orchestration and management. Implementation points: one container per microservice, use Docker Compose or Kubernetes for orchestration, configure service discovery and load balancing, implement centralized log and monitoring management, use API Gateway for unified entry. Considerations: avoid oversized containers, set reasonable resource limits, handle inter-service dependencies, implement graceful degradation.
