Basic Standard Premium Enterprise Enterprise Flash
Not available Simplified cache ideal for development/testing. Production ready cache with primary/replica duplication. Advanced features such as clustering and data persistence that are important to many enterprises. All the functionality of the Premium tier, plus powerful enterprise-ready features such as Redis Modules and active geo-replication. The same powerful reliability of the Enterprise tier, but running on fast non-volatile storage for massive, yet cost-effective, cache implementations.

Basic

A single node cache is a single node cache which is ideal for development/test and non-critical workloads. There’s no SLA on basic tier. Network isolation is available through Azure Private Link integration.

Standard

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. Network isolation is available through Azure Private Link integration.

Premium

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 the following:

  • 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.
  • Azure Virtual Network  deployment provides enhanced security and isolation for your Azure Cache for Redis, as well as subnets, access control policies and other features to further restrict access.
  • Multi-replica support allows up to three replica nodes to be created per cache or shard, expanding the reliability of the cache. Replicas can be created in the same data centre or across availability zones. Reserve pricing is available for additional replica nodes, although data transfers between availability zones are subject to applicable networking charges.

Enterprise

The Enterprise tier integrates powerful capabilities from Redis Labs’ Redis Enterprise software to provide a high-performance option that will meet the needs of the most demanding enterprise. Whether creating a new app or migrating an existing Redis Enterprise instance, this tier offers important features such as:

  • Redis Module support for RediSearch, RedisBloom and RedisTimeSeries. These modules add data types that unlock new data analysis, machine learning, stream analytics and IoT use cases.
  • Active Geo-replication that enables globally distributed caches with local latency. The use of conflict-free data types allows for multi-master writes with strong eventual consistency.
  • Higher availability (architected for up to 99.999 per cent) for enterprise-level reliability and peace of mind.

1-year and 3-year reservation pricing is also available. Contact Azure sales for more information.

Enterprise Flash

The Enterprise Flash tier runs on a combination of RAM and flash non-volatile memory storage. While taking a small but often negligible performance hit, this setup enables massive cache sizes – up to 13 TB with clustering. The use of flash storage also offers a lower price per GB that unlocks cost savings at scale. This tier also features active geo-replication and higher availability – up to 99.999 per cent.

1-year and 3-year reservation pricing is also available. Contact Azure sales for more information.

Zone redundancyPreview

Caches in the Premium, Enterprise and Enterprise Flash tiers are capable of hosting replica nodes in different availability zones (AZs), increasing availability and resiliency against a single point of failure. If the primary data centre were to fail, the cache would automatically fail over to the paired replica cache in the matching availability zone. With multi-AZ redundancy and using at least three replicas, availability increases to up to 99.99% for the Enterprise tiers.

The number of additional replica nodes needed depends on your clustering and replica configuration. Learn more in our documentation guide. In addition to paying the standard charges for the primary and the replica cache nodes, you will also pay some charges for the data transfer between AZs. Geo-replication is not yet available in conjunction with zone redundancy.

Geo-replication

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. In the Premium tier, you can read from or write to the primary cache instance, but you can only read from the replica cache instance. In the Enterprise and Enterprise Flash tiers, you can read and write to both the primary and replica caches. Enabling active geo-replication in the Enterprise and Enterprise Flash tiers increases availability to up to 99.999%. 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 not available in the Standard or Basic tiers.

Frequently asked questions

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

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

  • These tiers have prices comprised of two components: an infrastructure price and a software IP price. The infrastructure price is billed through Azure, while the software IP price goes to Redis Labs through the Azure Marketplace. The final price that you pay is the sum of these prices.
