Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month fall on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the upcoming month. Sign in to the Azure pricing calculator to see pricing based on your current program/offer with Microsoft.

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.
| Cache Name | Cache Size | Network performance | Number of Client Connections | Price |
|---|---|---|---|---|
| C0 | 250 MB | Low | 256 | $- |
| C1 | 1 GB | Low | 1,000 | $- |

| C5 | 26 GB | Moderate | 15,000 | $- |
| C6 | 53 GB | High | 20,000 | $- |
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.
| Cache Name | Cache Size | Network performance | Number of Client Connections | Price (two-node) |

| C6 | 53 GB | High | 20,000 | $- |
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:
- 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 datacenter 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 like:
- Redis Module support for RediSearch, RedisJSON, RedisBloom, and RedisTimeSeries. These modules add data types that unlocks vector search, data analysis, machine learning, and stream analytics.
- 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 percent) for enterprise-level reliability and peace of mind.

1-year and 3-year reserved pricing is available. Please contact your sales representative for more information.
*E1 cache is recommended for dev/testing only.
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 4.5 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 percent.
| Cache Name | Cache Size | Network performance | Number of Client Connections | Infrastructure Cost (pay as you go, three-node) | Software IP Cost (pay as you go, three-node) | Total Cost (pay as you go, three-node) |

1-year and 3-year reserved pricing is available. Please contact your sales representative for more information.
Zone Redundancy
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 datacenter 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 3 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 only available in conjunction with zone redundancy in the Enterprise and Enterprise Flash tiers.
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.

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 you pay is the sum of these prices.
