Azure VM Scaleset
Overview
Azure Virtual Machine Scale Sets (VMSS) is a feature provided by Microsoft Azure that enables automatic scaling of a group of identical virtual machines. VMSS allows you to deploy and manage a set of virtual machines as a single unit, ensuring high availability and automatically adjusting capacity to meet changes in demand.
