How to approach this question
Identify the App Service features used for staging environments and A/B testing.
Full Answer
Azure App Service Deployment Slots allow you to deploy your app to a staging environment. You can validate the changes and then perform a swap, which exchanges the IP addresses of the slots, resulting in zero downtime. To test stability with live users, you use the App Service Traffic Routing feature (also known as Testing in Production), which allows you to route a specific percentage of traffic (e.g., 10%) to the staging slot.
Common mistakes
Selecting Traffic Manager. Traffic Manager is a DNS-based global load balancer. App Service Traffic Routing is the native feature for splitting traffic between slots.
