Azure Virtual Machine Scale Sets

Azure Virtual Machine Scale Sets is a compute resource in Microsoft Azure that allows you to create and manage a group of load-balanced, identical virtual machines (VMs). It automatically scales the number of VM instances in or out based on demand or a defined schedule, ensuring high availability and performance for applications. This service is commonly used for large-scale applications, batch processing, and container workloads.

Also known as: VMSS, Azure VM Scale Sets, Virtual Machine Scale Sets, Scale Sets, Azure Scale Sets

Why learn Azure Virtual Machine Scale Sets?
