Azure Reservations help customers to save money when they can make a duration commitment to an Azure service. Typically the duration is one or three years with, of course, the best savings to be made on a three-year commitment.
Today there are sixteen categories of Reservations ranging from Reserved Instances for virtual machines to Reserved Capacity for storage or database services, as well as Software Plans for Red Hat or SUSE Linux. Buying and managing Reservations, and understanding how discounts are applied can be confusing, but there’s some excellent Microsoft documentation available.

Microsoft announce that a monthly payment option is now available for some Azure Reservations. There aren’t any additional costs for choosing to pay monthly rather than upfront, although if you’re in a non-US-dollar market the actual monthly payment may vary dependent on the exchange rate. Monthly payments are available for the following services: virtual machines, SQL Database, SQL Data Warehouse, Cosmos DB, and the App Service stamp fee, and it’s an option you select when you buy the Reservation from the Azure Management Portal.

Azure Reservations are a way of pre-paying for an Azure resource over a one or three-year term to get the most cost-effective pricing. The Reservations family continues to grow: it started with Reserved Instances, a way of pre-paying for Azure virtual machine base compute, and was extended with Reserved Capacity, a way of pre-paying for Azure SQL Database compute capacity. Today the family also includes Software Reservations for SUSE Linux software, and Reserved Capacity for Azure Cosmos DB throughput.
