The modern CI/CD toolbox: Strategies for consistency and reliability (DEV335)

Key Takeaways

1. Automation is Foundational for Modern CI/CD

   • Automating deployment pipelines helps remove manual errors and speed up processes.
   • Ensures consistency across deployments.

2. Code Signing and Attestation

   • Helps ensure authenticity and integrity of changes.
   • Should be implemented selectively based on the needs of each project/service.

3. Proper Rollback Strategies

   • Important to have the ability to quickly rollback changes, as failures are inevitable.
   • Reduces downtime and enables faster recovery.

4. Detecting and Handling Drift

   • Drift occurs when manual changes are made outside of the CI/CD pipeline.
   • Detect drift using tools like CloudFormation drift detection, Terraform state tracking, etc.
   • Strive to minimize admin access to production environments.

5. Standardized and Portable Pipelines

   • Standardize pipeline definitions to ensure consistency and ease of use across projects.
   • Use tools like projen pipelines to define pipelines in a platform-agnostic way.

6. Continuous Configuration and Feature Flags

   • Decouple deployments from feature releases using feature flags.
   • Enables dynamic feature management and safer testing in production.

7. Community Involvement

   • Engage with the AWS community to share experiences and learn from others.
   • Contribute to open-source projects like projen pipelines to help improve the tooling.
