Prepay for Azure Database for MariaDB compute resources with reserved capacity
Azure Database for MariaDB now helps you save money by prepaying for compute resources compared to pay-as-you-go prices. With Azure Database for MariaDB reserved capacity, you make an upfront commitment on MariaDB servers for a one or three year period to get a significant discount on the compute costs. To purchase Azure Database for MariaDB reserved capacity, you need to specify the Azure region, deployment type, performance tier, and term.
You do not need to assign the reservation to specific Azure Database for MariaDB servers. An already running Azure Database for MariaDB 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 MariaDB 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 MariaDB Database server. At the end of the reservation term, the billing benefit expires, and the Azure Database for MariaDB are billed at the pay-as-you go price. Reservations do not auto-renew. For pricing information, see the Azure Database for MariaDB reserved capacity offering.

Determine the right server 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 databases instance 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 MariaDB database, and two memory optimized, Gen5 – 16 vCore MariaDB 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
