What Azure Managed Redis is

Azure Managed Redis is a Microsoft-operated in-memory data store hosted on Azure and based on Redis Enterprise software. Applications inside or outside Azure can use it, and it supports Redis version 7.4.x. The service is positioned as a cache and temporary data store, not a persistent primary database. Its tiers are Memory Optimized, Balanced, Compute Optimized, and Flash Optimized; the last moves less frequently accessed data from RAM to NVMe storage. In-memory tiers support JSON, search including vector search, probabilistic data structures, and time-series capability. Flash Optimized supports JSON but not the other listed data features. All tiers support private endpoints, TLS encryption, and Microsoft Entra authentication, but data in memory is not encrypted; persistence disks are encrypted at rest. Optional persistence writes snapshots to disk, while backup import and export use Azure Blob Storage without a built-in scheduler. Pricing is paid and varies by size and region; there is no free plan.

Who it suits

It suits applications that need an Azure-hosted cache or temporary data store, including those connecting from outside Azure. Teams should consider its tier-specific data features and its stated limits before choosing it for a workload.

What it does well

Supports Redis version 7.4.x.
Applications inside or outside Azure can connect.
Offers four performance tiers.
All tiers support private endpoints, TLS, and Entra authentication.
High availability is available.

What to know first

No free plan is listed.
Data in memory is not encrypted.
No built-in scheduler for import or export.
Not intended as a persistent primary database.

Limits

The service has no free plan. Flash Optimized supports JSON but not the other listed data capabilities supported by in-memory tiers; high availability is required for the SLA, which covers endpoint connectivity rather than data loss.
