Progressive Delivery strategies, including Blue/Green deployments, canary releases, feature flag rollouts, and feature delivery platforms, aim to enhance software delivery by ensuring safe releases, minimizing risk, and accelerating learning. These approaches help teams avoid downtime, limit the impact of potential failures, and facilitate learning during the release process. Blue/Green deployments focus on avoiding downtime through infrastructure duplication, while canary releases limit the initial impact by introducing updates to a small subset of users. Feature flag rollouts allow for granular control, enabling gradual exposure of new features, and feature delivery platforms provide extensive monitoring and experimentation capabilities to refine releases based on user feedback. By combining these strategies, teams can achieve a balance of speed, safety, and learning in software delivery, making Progressive Delivery a key component of modern software engineering practices.
