Answer: Canary Deployment
Overall explanation Correct option: Canary Deployment In a canary release deployment, total API traffic is separated at random into a production release and a canary release with a preconfigured ratio. Typically, the canary release receives a small percentage of API traffic and the production release takes up the rest. The updated API features are only visible to API traffic through the canary. You can adjust the canary traffic percentage to optimize test coverage or performance.
