Explanation

To ensure that communication between the web servers and the business logic tier spreads equally across virtual machines, an internal load balancer should be recommended. An Azure Internal Load Balancer (ILB) is designed to provide network load balancing for virtual machines located within a cloud service or a virtual network, distributing traffic evenly among them.

To protect the web servers from SQL injection attacks, an application gateway that uses the WAF tier should be recommended. The Azure Web Application Firewall (WAF) tier on Azure Application Gateway offers centralized protection against common web exploits and vulnerabilities, including SQL injection attacks, by inspecting incoming traffic and blocking malicious requests.
