Progressive Delivery in CI/CD

Progressive Delivery is a modern approach to software deployment that allows teams to release features gradually to a subset of users. This technique helps in validating new features and minimizing the risk associated with releases. In a CI/CD (Continuous Integration/Continuous Deployment) pipeline, it enables teams to automate the delivery process while maintaining high quality.

• Progressive Delivery focuses on risk management during deployments.
• It allows for real-time monitoring and feedback.
• Canary releases and feature flags are common strategies used.
• Gradual rollouts help identify issues without impacting all users.

To implement Progressive Delivery in your CI/CD pipeline, follow these steps:

                graph TD;
                A[Code Commit] --> B[Automated Build];
                B --> C[Run Tests];
                C --> D{Deploy to Production};
                D --> |Canary Release| E[Monitor Performance];
                D --> |Full Rollout| F[Feature Toggle];
                E --> G{Feedback};
                F --> G;
                G --> |All Good| H[Complete Rollout];
                G --> |Issues Found| I[Rollback];
            

Here are some best practices for implementing Progressive Delivery:

1. Use automated testing to catch issues early.
2. Implement monitoring tools to track performance metrics.
3. Utilize feature flags to enable or disable features without redeployment.
4. Engage with users for feedback during the rollout phase.
5. Have a rollback plan ready in case of failures.
