MDFT Pro, a well-known training agency, is scaling their online learning platform to handle increasing student enrollments across multiple regions. Mark, the Scale Set Deployment Specialist, needs to deploy several Azure virtual machines running Windows Server 2019 in a virtual machine scale set using an ARM template.
These VMs will host their distributed learning management system that serves educational content to thousands of students globally. The architecture requires NGINX to be installed and configured on all virtual machines to act as a reverse proxy. Claire, the Application Deployment Coordinator, needs the solution to ensure that NGINX is automatically available on every VM instance during initial deployment or auto-scaling.
What should Mark use to ensure NGINX is available on all virtual machines in the scale set after they are deployed?
