The CI/CD process in Serverless architecture differs from traditional applications and needs to consider special requirements such as function deployment, environment management, and automated testing:
CI/CD process characteristics:
- Function-level deployment: Each function can be deployed and updated independently
- Infrastructure as code: Use SAM, Serverless Framework, Terraform and other tools to manage infrastructure
- Multi-environment management: Configuration management for development, testing, and production environments
- Rapid iteration: Support frequent code updates and deployments
Key components:
1. Source code management
- Version control: Use Git to manage code versions
- Branching strategy: Adopt Git Flow, GitHub Flow and other branching strategies
- Code review: Conduct code reviews through Pull Requests
2. Continuous Integration (CI)
- Code checking: Use ESLint, Prettier for code quality checks
- Unit testing: Write and run unit tests
- Build packaging: Use Webpack, Serverless Framework to package code
- Dependency scanning: Scan third-party dependencies for security vulnerabilities
3. Continuous Deployment (CD)
- Environment deployment: Automatically deploy to development, testing, and production environments
- Blue-green deployment: Achieve zero-downtime deployment
- Canary release: Gradual traffic switching to reduce risk
- Rollback mechanism: Quickly rollback to the previous stable version
4. Common tools
- AWS CodePipeline: AWS native CI/CD service
- GitHub Actions: GitHub integrated CI/CD platform
- CircleCI: Cloud-native CI/CD platform
- Serverless Framework: Supports deployment and management of Serverless applications
Candidates should be able to share CI/CD processes and best practices used in actual projects.
