Blue-Green & Gradual Rollouts
Deploy edge applications safely using blue-green deployments and gradual traffic rollouts to minimize risk and enable instant rollback.
The Risk of Big-Bang Deploys
Shipping a new version to 100% of users at once is risky, a hidden bug hits everyone instantly.
Progressive deployment strategies reduce blast radius by exposing changes gradually and enabling fast rollback.
Blue-Green Deployments
In a blue-green setup you run two environments:
- Blue, the current live version
- Green, the new version, fully deployed but not yet receiving traffic
You switch traffic to green when ready, and switch back instantly if something breaks.
