Overview
Progressive Delivery combines deployment strategies like Canary Releases and Feature Flags with advanced observability and automation. It focuses on reducing the risk of changes by controlling who sees what and when, based on real-time feedback.
Key Concepts
- Release Orchestration: Automating the stages of a rollout (e.g., 1%, 5%, 25%, 100%).
- Observability-Driven Rollouts: Using metrics to automatically decide whether to proceed or roll back.
- User Segmentation: Releasing features to specific groups (e.g., internal employees, beta testers).
Benefits
- Maximum Safety: Minimizes the impact of failures through automated guardrails.
- Faster Feedback: Get real-world data on new features earlier in the process.
- Improved Developer Confidence: Reduces the stress associated with large-scale deployments.
