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.
