# Prepay for Azure Data Explorer markup units with Azure Data Explorer reserved capacity
# Prepay for Azure Data Explorer markup units with Azure Data Explorer reserved instances

Save money with Azure Data Explorer by prepaying for the markup units compared to pay-as-you-go prices. With Azure Data Explorer reserved capacity, you make a commitment for Azure Data Explorer use for a period of one or three years to get a significant discount on the Azure Data Explorer markup costs. To purchase Azure Data Explorer reserved capacity, you only need to specify the term, it will apply to all deployments of Azure Data Explorer in all regions.
Save money with Azure Data Explorer by prepaying for the markup units compared to pay-as-you-go prices. By using Azure Data Explorer reserved instances, you make a commitment for Azure Data Explorer use for a period of one or three years to get a significant discount on the Azure Data Explorer markup costs. To purchase Azure Data Explorer reserved instances, you only need to specify the term; it applies to all deployments of Azure Data Explorer in all regions.

When you purchase a reservation, you prepay for the markup costs for a period of one or three years. As soon as you buy a reservation, the Azure Data Explorer markup charges that match the reservation attributes are no longer charged at the pay-as-you-go rates. Azure Data Explorer clusters that are already running or ones that are newly deployed automatically get the benefit. This reservation doesn't cover compute, networking, or storage charges associated with the clusters. You need to purchase savings plans for compute and reserved capacity for networking and storage resources separately. At the end of the reservation term, the billing benefit expires, and the Azure Data Explorer markup units are billed at the pay-as-you-go price. Reservations don't auto-renew. For pricing information, see the [Azure Data Explorer pricing page](https://azure.microsoft.com/pricing/details/data-explorer/).
