During this module, you will learn how to create a load balancer, add Probes, Backend pools and Load balancing rules.
Having two or more VMs in an Availability Set is a pre-requisite to fully create and configure a Load balancer. So if two VMs are not created and in an Availability set, go back to the VM creation lesson to complete this step.
After completing the exercises in this module, you will be able to:
- Create and configure a load balancer across VMs.
