Resource Overview​

Azure Linux Virtual Machine Scale Set is a computing resource that creates multiple Linux virtual machine instances with the same configuration and automatically scales the number of instances up or down based on demand or policies.
Large-scale workloads can be efficiently operated by configuring virtual network connections, VM SKUs, instance counts, image settings, authentication methods, disk settings, and network interface configurations.
