Quickstart: Create a Redis Enterprise cache

The Azure Cache for Redis Enterprise tiers provide fully integrated and managed Redis Enterprise on Azure. These tiers are:

  • Enterprise, which uses volatile memory (DRAM) on a virtual machine to store data
  • Enterprise Flash, which uses both volatile and nonvolatile memory (NVMe or SSD) to store data.

Both Enterprise and Enterprise Flash support open-source Redis 6 and some new features that aren't yet available in the Basic, Standard, or Premium tiers. The supported features include some Redis modules that enable other features like search, bloom filters, and time series.


Availability by region

Azure Cache for Redis is continually expanding into new regions. To check the availability by region for all tiers, see Products available by region.

Create a cache

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

  2. On the New page, select Databases and then select Azure Cache for Redis.

    Select Azure Cache for Redis

  3. On the New Redis Cache page, configure the settings for your new cache.

    Setting Choose a value Description
    Subscription Drop down and select your subscription. The subscription under which to create this new Azure Cache for Redis instance.
    Resource group Drop down and select a resource group, or select Create new and enter a new resource group name. 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 name that is unique in the region. The cache name must be a string between 1 and 63 characters when combined with the cache's region name that contain only numbers, letters, or hyphens. (If the cache name is fewer than 45 characters long it should work in all currently available regions.) The name must start and end with a number or letter, and can't contain consecutive hyphens. Your cache instance's host name is \<DNS name\>.\<Azure region\>.redisenterprise.cache.azure.net.
    Location Drop down and select a location. Enterprise tiers are available in selected Azure regions.
    Cache type Drop down and select an Enterprise or Enterprise Flash tier and a size. The tier determines the size, performance, and features that are available for the cache.

    Be sure to select Terms before you proceed.

  4. Select Next: Networking and skip.

  5. Select Next: Advanced.

    Enable Non-TLS access only if you plan to connect to the new cache without using TLS. Disabling TLS is not recommended, however. You can't change the eviction policy or clustering policy of an Enterprise cache instance after you create it. If you're using this cache instance in a replication group, be sure to know the policies of your primary nodes before you create the cache. For more information on replication, see Active geo-replication prerequisites.

    Set Clustering policy to Enterprise for a nonclustered cache. For more information on choosing Clustering policy, see Clustering Policy.

    Screenshot that shows the Enterprise tier Advanced tab.


    Enterprise and Enterprise Flash tiers are inherently clustered, in contrast to the Basic, Standard, and Premium tiers. Redis Enterprise supports two clustering policies.

    • Use the Enterprise policy to access your cache using the Redis API.
    • Use OSS to use the OSS Cluster API. For more information, see Clustering on Enterprise.


    You can't change modules after you create a cache instance. Modules must be enabled at the time you create an Azure Cache for Redis instance. There is no option to enable the configuration of a module after you create a cache.

  6. Select Next: Tags and skip.

  7. Select Next: Review + create.

    Enterprise tier Review + Create tab

  8. Review the settings and select Create.

    It takes some time for the cache to create. You can monitor progress on the Azure Cache for Redis Overview page. When Status shows as Running, the cache is ready to use.

Clustering Policy

The OSS Cluster mode allows clients to communicate with Redis using the same Redis Cluster API as open-source Redis. This mode provides optimal latency and near-linear scalability improvements when scaling the cluster. Your client library must support clustering to use the OSS Cluster mode.

The Enterprise Cluster mode is a simpler configuration that exposes a single endpoint for client connections. This mode allows an application designed to use a standalone, or nonclustered, Redis server to seamlessly operate with a scalable, multi-node, Redis implementation. Enterprise Cluster mode abstracts the Redis Cluster implementation from the client by internally routing requests to the correct node in the cluster. Clients aren't required to support OSS Cluster mode.

In this quickstart, you learned how to create an Enterprise tier instance of Azure Cache for Redis.
