Progressive Delivery is a software release strategy that cleverly integrates feature flags, canary releases, and phased rollouts. This blend allows you to deploy new features incrementally to a selected group of users prior to a complete rollout. Essentially, it's about taking cautious, measured steps.

• Feature Flags: Toggle new functionalities on and off for specific user segments without deploying new codebase changes to everyone.

• Canary Releases: Introduce new features to a small percentage of your users to assess stability and performance.

• Phased Rollouts: Gradually extend the release to larger groups, monitoring and refining at each stage.

This method helps your team reduce deployment risks by identifying potential issues early, using real user feedback to guide adjustments. It also ensures that your system remains stable and responsive, avoiding the pitfalls of widespread disruptions from less controlled releases. By applying Progressive Delivery, you maintain a tight grip on the quality and user experience of your product updates.

Examples of Progressive Delivery

Canary Releases: You release a new feature to a select few. This tests both impact and performance. Feedback then informs the broader rollout. Learn more about Canary Releases.

Feature Flags: Here, you control feature availability directly in the live environment. Toggle on or off without full deployments. It’s about safe, controlled updates. Discover more on implementing feature flags with Feature Flag Best Practices.

Phased Rollouts: Start small, then expand. Each phase brings more users, guided by ongoing feedback and performance metrics. Stability is key throughout this process. Explore Phased Rollouts and Continuous Delivery.
