Testing in production anti-pattern
QUOTE: Canary releases are similar to blue-green deployments. Instead of switching all traffic to the updated application, you route only a small portion of the traffic to the new deployment. If there's a problem, revert to the old deployment. If not, gradually route more traffic to the new version. If you're using Azure App Service, you can use the **Testing in production feature** to manage a canary release. END-QUOTE
