| 1 |
Design Around Business Capabilities |
Structure microservices based on business domains and bounded contexts rather than technical layers. |
Better scalability, maintainability, and team autonomy. |
| 2 |
Keep Services Small and Focused |
Each service should have a single responsibility and perform one business function well. |
Easier development, testing, and deployment. |
| 3 |
Use API-First Development |
Define and document APIs before implementation using standards such as OpenAPI. |
Improved consistency and easier integration. |
| 4 |
Implement Independent Deployment |
Services should be deployable without affecting other services. |
Faster releases and reduced downtime. |
| 5 |
Adopt Containerization |
Package services using containers such as Docker for consistent environments. |
Portability, scalability, and simplified deployment. |
| 6 |
Build for Failure |
Assume services may fail and implement retries, circuit breakers, timeouts, and fallback mechanisms. |
Improved system resilience and availability. |
| 7 |
Centralize Logging and Monitoring |
Collect logs, metrics, and traces across all services. |
Faster troubleshooting and performance optimization. |
| 8 |
Secure Every Service |
Use authentication, authorization, encryption, API gateways, and secrets management. |
Enhanced security and compliance. |
| 9 |
Use Event-Driven Communication When Appropriate |
Employ message brokers and asynchronous communication for loosely coupled services. |
Better scalability and reduced dependencies. |
| 10 |
Automate Testing and CI/CD |
Implement automated unit, integration, performance, and security testing within CI/CD pipelines. |
Higher quality releases and faster delivery. |
