A solutions architect is designing a highly available and scalable web application on Azure. The application will be deployed across multiple Azure Virtual Machines (VMs) and must be accessible via a single public IP address. Additionally, the solution requires advanced traffic management capabilities, such as SSL termination, web application firewall (WAF) protection, and URL-based routing. Which Azure service should the architect recommend to meet these requirements?

Why the other options are wrong

• A. Azure Traffic Manager is a DNS-based traffic load balancer that operates at the DNS level (Layer 7) for global distribution but does not offer features like SSL termination or WAF at the entry point.
• B. Azure Load Balancer operates at the transport layer (Layer 4) and does not provide advanced application-layer features like SSL termination, WAF, or URL-based routing.
• C. Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications. While it offers WAF and SSL termination, it's typically for global distribution and CDN, not primarily for internal load balancing within a single region or VNet for VMs behind a single public IP, which is better suited for Application Gateway.
