Prepay for SQL Database compute resources with Azure SQL Database reserved capacity

Save money with Azure SQL Database by prepaying for Azure SQL Database compute resources compared to pay-as-you-go prices. With Azure SQL Database reserved capacity, you make an upfront commitment on SQL Database for a period of one or three years to get a significant discount on the compute costs. To purchase SQL Database reserved capacity, you need to specify the Azure region, deployment type, performance tier, and term.

You do not need to assign the reservation to SQL Database instances. Matching SQL Database instances, that are already running or ones that are newly deployed, will automatically get the benefit. By purchasing a reservation, you are pre-paying for the compute costs for the SQL Database instances for a period of one or three years. As soon as you buy a reservation, the SQL Database compute charges that match the reservation attributes are no longer charged at the pay-as-you go rates. A reservation does not cover software, networking, or storage charges associated with the SQL Database instance. At the end of the reservation term, the billing benefit expires and the SQL Databases are billed at the pay-as-you go price. Reservations do not auto-renew. For pricing information, see the SQL Database reserved capacity offering.

You can buy Azure SQL Database reserved capacity in the Azure portal. To buy SQL Database reserved capacity:

  • You must be in the Owner role for at least one Enterprise or Pay-As-You-Go subscription.
  • For Enterprise subscriptions, Azure reservation purchases must be enabled in the EA portal.
  • For Cloud Solution Provider (CSP) program, only the admin agents or sales agents can purchase SQL Database reserved capacity.

The details on how enterprise customers and Pay-As-You-Go customers are charged for reservation purchases, see Understand Azure reservation usage for your Enterprise enrollment and Understand Azure reservation usage for your Pay-As-You-Go subscription.

Determine the right SQL size before purchase

The size of reservation should be based on the total amount of compute used by the existing or soon-to-be-deployed SQL single databases and/or elastic pools within a specific region and using the same performance tier and hardware generation.

For example, let's suppose that you are running one general purpose, Gen5 – 16 vCore elastic pool, and two business critical, Gen5 – 4 vCore single databases. Further, let's supposed that you plan to deploy within the next month an additional general purpose, Gen5 – 16 vCore elastic pool, and one business critical, Gen5 – 32 vCore elastic pool. Also, let's suppose that you know that you will need these resources for at least 1 year. In this case you should purchase a 32 (2x16) vCores, 1 year reservation for SQL Database Single/Elastic Pool General Purpose - Compute Gen5 and a 40 (2x4 + 32) vCore 1 year reservation for SQL Database Single/Elastic Pool Business Critical - Compute Gen5.

    • Single subscription - The vCore reservation discount is applied to SQL Database instances in this subscription.
    • Shared - The vCore reservation discount is applied to SQL Database instances running in any subscriptions within your billing context. For enterprise customers, the shared scope is the enrollment and includes all subscriptions (except dev/test subscriptions) within the enrollment. For Pay-As-You-Go customers, the shared scope is all Pay-As-You-Go subscriptions created by the account administrator.
    Region The Azure region that’s covered by the SQL Database reserved capacity reservation.
    Deployment Type The SQL resource type that you want to buy the reservation for.
    Performance Tier The service tier for the SQL Database instances.
    Term One year or three years.
    Quantity The number of instances being purchased within the SQL Database reserved capacity reservation. The quantity is the number of running SQL Database instances that can get the billing discount. For example, if you are running 10 SQL Database instances in the East US, then you would specify quantity as 10 to maximize the benefit for all running machines.

Cancellations and exchanges

If you need to cancel your SQL Database reserved capacity reservation, there may be a 12% early termination fee. Refunds are based on the lowest price of either your purchase price or the current price of the reservation. Refunds are limited to $50,000 per year. The refund you receive is the remaining pro-rated balance minus the 12% early termination fee. To request a cancellation, go to the reservation in the Azure portal and select Refund to create a support request.

If you need to change your SQL Database reserved capacity reservation to another region, deployment type, performance tier, or term, you can exchange it for another reservation that's of equal or greater value. The term start date for the new reservation doesn't carry over from the exchanged reservation. The 1 or 3 year term starts from when you create the new reservation. To request an exchange, go to the reservation in the Azure portal, and select Exchange to create a support request.

vCore size flexibility

vCore size flexibility helps you scale up or down within a performance tier and region, without losing the reserved capacity benefit. SQL Database reserved capacity also provides you with the flexibility to temporarily move your hot databases between pools and single databases as part of your normal operations (within the same region and performance tier) without losing the reserved capacity benefit. By keeping an un-applied buffer in your reservation, you can effectively manage the performance spikes without exceeding your budget.

Next steps

The vCore reservation discount is applied automatically to the number of SQL Database instances that match the SQL Database reserved capacity reservation scope and attributes. You can update the scope of the SQL Database reserved capacity reservation through Azure portal, PowerShell, CLI or through the API.
