✑ The number of VMs that are running at any given point in time must change when the user workload changes.
✑ When a new version of the application is available in Azure Marketplace it must be deployed without causing application downtime.
✑ Use VM scale sets.
✑ Minimize the need for ongoing maintenance.

Introduction to Azure managed disks https://docs.microsoft.com/en-us/azure/virtual-machines/windows/managed-disks-overview "Using managed disks, you can create up to 50,000 VM disks of a type in a subscription per region, allowing you to create thousands of VMs in a single subscription. This feature also further increases the scalability of virtual machine scale sets by allowing you to create up to 1,000 VMs in a virtual machine scale set using a Marketplace image."
