Load Balancer
Your web app runs on an App Service Plan. Scale the plan to N instances and Azure’s built-in load balancer spreads requests across every copy.
One plan, five instancesThe App Service Plan defines the machines. Set the instance count to 5 and Azure runs 5 identical copies of your web app.
DNS points to the app, not a VMYour custom domain’s CNAME resolves to the app’s front end — clients never target an individual instance.
Load balancing is built inThe front end spreads requests across healthy instances and adjusts automatically as you scale out or in.
