Azure Cache for Redis provides a fully managedopen-source Redis cache within Azure. You can start with a Basic, Standard, or Premium tier cache of any size, and scale it to meet your application's performance needs. This quickstart demonstrates how to use the Azure portal to create a new Azure Cache for Redis instance.

Prerequisites

You need an Azure subscription before you begin. If you don't have one, create afree account.

Create a cache

1. In theAzure portal, search for and selectAzure Cache for Redis.

2. On theAzure Cache for Redis page, selectCreate >Azure Cache for Redis.

3. On theBasics tab of theNew Redis Cache page, configure the following settings:

   • Subscription: Select the subscription to use.
   • Resource group: Select a resource group, or selectCreate new and enter a new resource group name. Putting all your app resources in the same resource group lets you easily manage or delete them together.
   • Name: Enter a cache name that's unique in the region. The name must:
     • Be a string of 1 to 63 characters.
     • Contain only numbers, letters, and hyphens.
     • Start and end with a number or letter.
     • Not contain consecutive hyphens.
   • Region: Select anAzure region near other services that use your cache.
   • Cache SKU: Select aSKU to determine the available sizes, performance, and features for your cache.
   • Cache size: Select a cache size. For more information, seeAzure Cache for Redis overview.

   

4. Select theNetworking tab, or selectNext: Networking.

5. On theNetworking tab, select a connectivity method to use for the cache.Private Endpoint is recommended for security. If you selectPrivate Endpoint, selectAdd private endpoint and create the private endpoint.

6. Select theAdvanced tab, or selectNext: Advanced.

7. On theAdvanced pane, configure the following options:

   • SelectMicrosoft Entra Authentication orAccess Keys Authentication.Microsoft Entra Authentication is enabled by default.
   • Choose whether toEnable the non-TLS port.
   • For a Premium cache, you can configure or disableAvailability zones. You can't disable availability zones after the cache is created. For a Standard cache, availability zones are allocated automatically. Availability zones aren't available for Basic SKU.
   • For a Premium cache, configure the settings forReplica count,Clustering andShard count,System-assigned managed identity, andData persistence.

   The following image shows theAdvanced tab for the Standard SKU.

   

   Important

   Use Microsoft Entra ID with managed identities to authorize requests against your cache if possible. Authorization using Microsoft Entra ID and managed identity provides better security and is easier to use than shared access key authorization. For more information about using managed identities with your cache, seeUse Microsoft Entra ID for cache authentication.

8. Optionally, select theTags tab or selectNext: Tags, and enter tag names and values to categorize your cache resources.

9. SelectReview + create, and once validation passes, selectCreate.

The new cache deployment takes several minutes. You can monitor deployment progress on the portal Azure Cache for Redis page. When the cacheStatus displaysRunning, the cache is ready to use.
