By leveraging Azure App Service, organizations can transform how they deliver applications while maintaining robust performance and availability. ## Configuration ### URL Each Web App you create needs to be assigned a globally unique URL with the default domain of `<>.azurewebsites.net` In practice, you won't use this azure websites URL as the public facing domain name. Instead, you'll register your custom domain with the web app using a CNAME record to point to the azure backend URL. [[Deployment Slots]]
