Azure Database for MySQL now helps you save money by prepaying for compute resources compared to pay-as-you-go prices. With Azure Database for MySQL reserved instances, you make an upfront commitment on MySQL server for a one or three year period to get a significant discount on the compute costs. To purchase Azure Database for MySQL reserved capacity, you need to specify the Azure region, deployment type, performance tier, and term.
How does the instance reservation work?
You do not need to assign the reservation to specific Azure Database for MySQL servers. An already running Azure Database for MySQL or ones that are newly deployed, will automatically get the benefit of reserved pricing. By purchasing a reservation, you are pre-paying for the compute costs for a period of one or three years. As soon as you buy a reservation, the Azure database for MySQL 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 MySQL Database server. At the end of the reservation term, the billing benefit expires, and the Azure Database for MySQL are billed at the pay-as-you go price. Reservations do not auto-renew. For pricing information, see the Azure Database for MySQL reserved capacity offering.
You can buy Azure Database for MySQL reserved capacity in the Azure portal. Pay for the reservation up front or with monthly payments. To buy the reserved capacity:
- You must be in the owner role for at least one Enterprise or individual subscription with pay-as-you-go rates.
- For Enterprise subscriptions, Add Reserved Instances must be enabled in the EA portal. Or, if that setting is disabled, you must be an EA Admin on the subscription.
- For Cloud Solution Provider (CSP) program, only the admin agents or sales agents can purchase Azure Database for MySQL reserved capacity.

Reservation exchanges and refunds
You can exchange a reservation for another reservation of the same type, you can also exchange a reservation from Azure Database for MySQL - Single Server with Flexible Server. It's also possible to refund a reservation, if you no longer need it. The Azure portal can be used to exchange or refund a reservation. For more information, see Self-service exchanges and refunds for Azure Reservations.
Reservation discount
You may save up to 67% on compute costs with reserved instances. In order to find the discount for your case, please visit the Reservation blade on the Azure portal and check the savings per pricing tier and per region. Reserved instances help you manage your workloads, budget, and forecast better with an upfront payment for a one-year or three-year term. You can also exchange or cancel reservations as business needs change.
Determine the right database 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 server 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 – 32 vCore MySQL database, and two memory optimized, Gen5 – 16 vCore MySQL databases. Further, let's supposed that you plan to deploy within the next month an additional general purpose, Gen5 – 32 vCore database server, and one memory optimized, Gen5 – 16 vCore database server. Let's suppose that you know that you will need these resources for at least 1 year. In this case, you should purchase a 64 (2x32) vCores, 1 year reservation for single database general purpose - Gen5 and a 48 (2x16 + 16) vCore 1 year reservation for single database memory optimized - Gen5

| Scope | The vCore reservation's scope can cover one subscription or multiple subscriptions (shared scope). If you select: Shared, the vCore reservation discount is applied to Azure Database for MySQL servers running in any subscriptions within your billing context. For enterprise customers, the shared scope is the enrollment and includes all 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. Single subscription, the vCore reservation discount is applied to Azure Database for MySQL servers in this subscription. Single resource group, the reservation discount is applied to Azure Database for MySQL servers in the selected subscription and the selected resource group within that subscription. |
| Region | The Azure region that's covered by the Azure Database for MySQL reserved capacity reservation. |
| Deployment Type | The Azure Database for MySQL resource type that you want to buy the reservation for. |
| Performance Tier | The service tier for the Azure Database for MySQL servers. |
| Term | One year |
| Quantity | The amount of compute resources being purchased within the Azure Database for MySQL reserved capacity reservation. The quantity is a number of vCores in the selected Azure region and Performance tier that are being reserved and will get the billing discount. For example, if you are running or planning to run an Azure Database for MySQL servers with the total compute capacity of Gen5 16 vCores in the East US region, then you would specify quantity as 16 to maximize the benefit for all servers. |
