Each microservice should manage its own data. Avoid sharing databases between services to maintain loose coupling.
6.2 Use API Gateways
Use API gateways to route requests, manage security, and aggregate responses. This decouples client interactions from internal microservice implementation details.
6.3 Embrace Asynchronous Communication
For better performance, microservices can communicate asynchronously using message brokers (like Kafka or RabbitMQ) instead of always relying on synchronous REST calls.
6.4 Monitoring and Observability
Use distributed tracing and monitoring tools (e.g., Prometheus, Jaeger) to keep track of how services are interacting and to identify bottlenecks.
6.5 Automate Testing and Deployment (CI/CD)
Each microservice should be tested independently, and continuous integration (CI) and continuous deployment (CD) pipelines should be in place to automate the testing and deployment process.
