Simplicity meets flexibility
Select and purchase Azure Reserved VM Instances in three easy steps—specify your Azure region, virtual machine type, and term (one year or three years)—that's it.

While Azure Reserved VM Instances require making upfront commitments on compute capacity, they also provide flexibility should your business needs change. Easily exchange or cancel reserved instances at any time.

Optimize your reservation with instance size flexibility
Your business and applications requirements continuously evolve, so committing to a specific VM size ahead of time—to take advantage of the price discounts that Azure Reserved VM Instances offer—can be limiting.

Simplify the management of reserved instances by choosing to optimize for instance size flexibility. With instance size flexibility, Azure can automatically apply your reserved instances to other VM sizes within the same group and region. You'll spend less time managing your reservations and you may also reduce costs. Let Azure increase your overall reserved instance usage while you focus on innovative projects that can fuel business growth.

Reserve compute capacity in advance with on-demand capacity reservations
On-demand capacity reservations enable you to reserve compute capacity for one or more virtual machine size(s) in an Azure region or Availability Zone for any length of time. You can create and cancel an on-demand capacity reservation at any time, no commitment is required. The ability for you to access compute capacity – with SLAs and ahead of actual VM deployments - is particularly important to ensure the availability of mission-critical applications running on Azure. Use capacity reservations to meet your business continuity and disaster recovery needs. Combine capacity reservations with Reserved Virtual Machine Instances to greatly reduce costs.
