Quickstart: Create an open-source Redis cache

  • Artikkeli

Azure Cache for Redis provides fully managed open-source Redis within Azure. You can start with an Azure Cache for Redis instance of any tier (Basic, Standard, or Premium) and 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.

Prerequisites

You'll need an Azure subscription before you begin. If you don't have one, create a free account first.

Create a cache

  1. To create a cache, sign in to the Azure portal. On the portal menu, select Create a resource.

    Sceenshot that shows the Create a resource option highlighted on the left navigation pane in the Azure portal.

  2. On the Get Started pane, enter Azure Cache for Redis in the search bar. In the search results, find Azure Cache for Redis, and then select Create.

  3. On the New Redis Cache pane, on the Basics tab, configure the following settings for your cache:

    Setting Action Description
    Subscription Select your Azure subscription. The subscription to use to create the new instance of Azure Cache for Redis.
    Resource group Select a resource group, or select Create new and enter a new resource group name. A name for the resource group in which to create your cache and other resources. By putting all your app resources in one resource group, you can easily manage or delete them together.
    DNS name Enter a unique name. The cache name must be a string of 1 to 63 characters that contains only numbers, letters, and hyphens. The name must start and end with a number or letter, and it can't contain consecutive hyphens. Your cache instance's host name is \<DNS name>.redis.cache.windows.net.
    Location Select a location. An Azure region that is near other services that use your cache.
    Cache SKU Select a SKU. The SKU determines the size, performance, and feature parameters that are available for the cache. For more information, see Azure Cache for Redis overview.
    Cache size Select a cache size. For more information, see Azure Cache for Redis overview.

  4. Select the Networking tab or select Next: Networking.

  5. On the Networking tab, select a connectivity method to use for the cache.

  6. Select the Advanced tab or select Next: Advanced.

  7. On the Advanced pane, verify or select an authentication method based on the following information:

    Screenshot showing the Advanced pane and the available options to select.

    • By default, for a new Basic, Standard, or Premium cache, Microsoft Entra Authentication is enabled and Access Keys Authentication is disabled.
    • For Basic or Standard caches, you can choose the selection for a non-TLS port.
    • For Standard and Premium caches, you can choose to enable availability zones. You can't disable availability zones after the cache is created.
    • For a Premium cache, configure the settings for non-TLS port, clustering, managed identity, and data persistence.

    Important

    For optimal security, we recommend that you use Microsoft Entra ID with managed identities to authorize requests against your cache if possible. Authorization by using Microsoft Entra ID and managed identities provides superior security and ease of use over shared access key authorization. For more information about using managed identities with your cache, see Use Microsoft Entra ID for cache authentication.

  8. (Optional) Select the Tags tab or select Next: Tags.

  9. (Optional) On the Tags tab, enter a tag name and value if you want to categorize your cache resource.

  10. Select the Review + create button.

    On the Review + create tab, Azure automatically validates your configuration.

  11. After the green Validation passed message appears, select Create.

A new cache deployment occurs over several minutes. You can monitor the progress of the deployment on the Azure Cache for Redis Overview pane. When Status displays Running, the cache is ready to use.
