Final answer:
Azure VMs are billed by the minute, which allows for more precise billing and cost savings for the users by not rounding up to the nearest hour.
Step-by-step explanation:
Azure Virtual Machines (VMs) are billed by the minute. This billing model provides a more precise billing method compared to hourly billing, allowing customers to pay only for the compute time they actually use. For example, if you run a VM for 10 minutes, you will be billed for those 10 minutes rather than for a full hour. Azure VMs offer a flexible and scalable cloud computing solution, where you can choose from a wide range of VM sizes and types to meet the specific requirements of your applications and workloads.
