By default, a replicated cache is a two-node primary/secondary configuration. We manage automatic replication between the nodes to offer a high-availability SLA.

Premium tier includes all the standard-tier features and more, such as better performance over basic or standard-tier caches, bigger workloads, disaster recovery, and enhanced security. Additional features include:

  • Redis persistence allows you to persist data stored in Redis cache. You can also take snapshots and back up the data which you can load in case of a failure.
  • Redis Cluster automatically shards data across up to ten Redis nodes, so you can create larger workloads (up to 1.2 TB) and get better performance.
  • Multi-replica support allows up to five read-only replica nodes to be created per shard, expanding the reliability of the cache and greatly increasing read throughput. Additional replica nodes can also use reserved pricing.

Geo-replication, when enabled, allows two separate Azure Cache for Redis instances across Azure regions to be linked together in a primary/replica relationship. The service maintains the linked primary and replica cache instances in sync. You can read from or write to the primary cache instance, but you can only read from the replica cache instance. In addition to paying the standard charges for the primary and the replica cache instances, you will also pay some charges for the data transfer between regions. Geo-replication is only available on the Azure Cache for Redis premium tier.

Support & SLA

  • We provide technical support for all Azure services released to general availability, including Azure Cache for Redis, through Azure Support, starting at $29/month. Billing and subscription management support is provided at no cost.
  • Service Level Agreement (SLA)—Azure Cache for Redis guarantees that a standard/premium cache will be available at least 99.9% of the time. Learn more about our SLA. The SLA only covers connectivity to the cache endpoints. The SLA does not cover protection from data loss. We recommend using Redis data persistence feature in the premium tier to increase resiliency against data loss.
  • There's no SLA for basic tier.


  • Managed Cache Service and In-Role were retired on November 30, 2016. For more information, see Azure Managed Cache and In-Role Cache services to be retired on 11/30/2016.

  • Save up to 55% on Azure Cache for Redis Premium tier with a one- or three-year term of reserved capacity. For more information, see documentation page.

  • Not quite. The Enterprise and Enterprise Flash tiers include many of the most popular features from Redis Enterprise, but they are not identical.

  • Azure Private Link enables private connectivity from a virtual network to Azure Cache for Redis, providing straightforward network isolation.
