Continuous Delivery (CD) and Continuous Deployment (CD) Principles and Practices

Ensure that the deployment process is consistent and repeatable, reducing the risk of errors and ensuring that each release is reliable.

Automate the deployment process to create a streamlined and efficient method for releasing software. This includes deploying to staging environments for additional testing.

Strive for parity between different environments, such as development, staging, and production, to minimize issues related to environment-specific differences.

In Continuous Delivery, automated processes ensure that the software is always in a deployable state. Deployment to production requires human intervention, allowing for a final review and decision before release.

Continuous Deployment takes automation a step further, automatically deploying changes to the production environment once they pass automated tests. Human intervention is minimized in the release process.

Use feature toggles or feature flags to enable or disable specific features in production. This allows for the decoupling of deployment and release, enabling the gradual rollout of features.

Implement mechanisms to quickly rollback releases in case of unexpected issues. This ensures a rapid response to problems without causing extended downtime.

Implement robust monitoring and logging to track the performance and behavior of the application in real-time. This facilitates rapid identification and resolution of issues in production.
