Explanation

An Azure Application Gateway is ideal for distributing traffic to private VMs running a web app, using a dedicated subnet within your VNet, providing internal load balancing and SSL termination while keeping the app private, which minimizes cost compared to public-facing solutions like front doors or public IPs on VMs, offering efficient, secure, internal traffic management. Key Components & Setup: Azure Virtual Network (VNet): Your isolated cloud network where all resources reside. Virtual Machines (VMs): Three VMs with only private IP addresses within a VNet subnet, hosting your web app instances (e.g., as a scale set or individual VMs). Dedicated Application Gateway Subnet: A separate, dedicated subnet in your VNet is required for the Application Gateway itself; no other resources can live there. Application Gateway: Deployed into that dedicated subnet, it acts as the internal load balancer. Backend Pool: The App Gateway's backend pool points to the private IPs of your three VMs. Listeners & Rules: Configure an internal listener (no public IP needed) on the App Gateway, routing traffic (e.g., HTTP/S) to the VMs via HTTP settings. https://learn.microsoft.com/en-us/azure/application-gateway/configuration-infrastructure
