Gradual deployment strategy that releases changes to a small subset of users first before rolling out to everyone. Like testing a new recipe on a few customers before adding it to the full menu.
Release the new feature to 5% of users, monitor for issues, then gradually increase to 25%, 50%, and finally 100% if everything works well.
These services provide tools and frameworks to implement gradual deployment strategies like Canary Deployment, allowing for controlled rollouts and monitoring.
