Azure Virtual Machines Scale Sets (VMSS) is an IaaS that allows you to create and manage a group of Virtual Machines (VM) behind a load balancer. Scale sets provide you the ability to increase and decrease the number of VMs based on the workload's requirement and user's demand. VMSS allows you to build large-scale infrastructure suitable for big data and compute.
VMSS helps improve the performance and redundancy of applications requiring a VM with a dedicated OS for hosting the workloads. Since the application is accessed through a load balancer, the requests are distributed to multiple workloads without overloading a single host.
In this hands-on lab, you will create a Scale Set and run an Nginx web server using VM Extension.
