Prepay for Azure Managed Redis compute resources with reservations

  • Applies to: ✅ Azure Managed Redis

Azure Managed Redis reservations reduce costs by prepaying for compute resources. You commit to a cache in exchange for significant compute cost discounts.

Reservations prepay compute costs for one or three years. Once purchased, matching compute charges use reserved rates instead of pay-as-you-go pricing.

Purchase reservations for a specific Azure region, Redis tier, term, and node quantity. You don't assign reservations to specific cache instances - existing and new caches automatically receive reserved pricing up to the total reservation size.

You can enable auto-renewal or let the reservation expire and revert to pay-as-you-go pricing. You can pay upfront or monthly. For details, see Buy a reservation.

For pricing information, see the Azure Managed Redis pricing page. Reservations don't cover networking or storage charges.

To buy a reservation:

  • You must have Owner or Reservation Purchaser role in the Azure subscription.
  • For Azure Managed Redis subscriptions, you must enable Add Reserved Instances in the EA portal. Or if that setting is disabled, you must be an EA Admin on the subscription.
  • For the Cloud Solution Provider (CSP) program, only the admin agents or sales agents can purchase Azure Managed Redis reservations. For more information, see Azure Reservations in Partner Center Cloud Solution Provider (CSP) program.

How to use the Azure portal to buy reservations:

  1. In the portal, search for and select Reservations and then select Add, or select this link to the Purchase reservations page.
  2. On the Purchase reservations page, select Azure Cache for Redis.
  3. In the Select the product you want to purchase pane, select the Scope and Subscription you want to use for the reservation.

The following list describes the form fields in detail.

For pay-as-you-go, the charges are billed to the subscription's credit card or invoice.
  • Scope: The reservation's scope.
    • Shared applies the reservation discount to cache instances in any subscriptions in your billing context. For EA, the shared scope is the enrollment and includes subscriptions within the enrollment. For pay-as-you-go, the shared scope is all pay-as-you-go subscriptions created by the account administrator.
    • Single subscription applies the reservation discount to cache instances in this subscription.
    • Single resource group applies the reservation discount to instances in the selected resource group within the subscription.
    • Management group applies the reservation discount to matching resources in subscriptions that are a part of both the management group and billing scope.
  • Region: The Azure region for the reservation.
  • Term: 1 year or 3 years.
  • Billing frequency: Monthly or Upfront.
  • Recommended quantity: The recommended number of nodes to reserve in the selected Azure region, tier, and scope. Select See details for details about recommended quantities.

Existing or new caches that match the attributes you select get the reservation discount. The actual number of instances that get the discount depends on the scope and quantity you select.

  1. Select the reservation you want, and note the Monthly price per node and estimated savings calculated at lower right.
  2. Select Add to cart and then select View cart to close the product list pane.
