In the first part of this chapter, we are going to look at some management capabilities for virtual machines. After creation, you can manage and change (vertical scale) the sizes of Windows and Linux VMs from the Azure portal, PowerShell, and CLI. Vertical scaling, also known as scale up and scale down, means increasing or decreasing VM sizes in response to different workloads.
In the upcoming demonstrations, we are going to resize VMs using the Azure portal and CLI.
