Deploy Azure Managed Redis with AzAPI using Terraform

Azure Managed Redis is now generally available – bringing the power of Redis Enterprise directly into the Azure ecosystem.

However, as of Terraform azure provider v4.5, some features like Persistence (RDB, AOF) and Non-Clustered mode are not yet supported.

The solution? Use the AzAPI provider to deploy Azure Managed Redis today with full feature coverage — and switch seamlessly to the native provider once support arrives.

Why Azure Managed Redis?

Azure Managed Redis combines Redis Enterprise’s performance and modules with Azure’s native managed experience.

You get:

• Enterprise-grade performance and high availability with up to 99.999% SLA*
• Native Azure billing, security, and identity integration
• Full module support: RedisJSON, RediSearch, RedisBloom, and RedisTimeSeries

This service is the evolution of Azure’s Redis offering — and the strategic path forward for Redis workloads in Azure.

* With recommended configuration of active georeplication.

Azure Cache for Redis Retirement!

Microsoft has announced a clear transition timeline for Azure Cache for Redis:

In short: New Redis deployments on Azure should use Azure Managed Redis, which brings Redis Enterprise features under Azure’s managed control plane.

Why Use AzAPI with Terraform?

The azurerm provider doesn’t yet expose all capabilities of Azure Managed Redis.Until it does, the AzAPI provider lets you interact directly with Azure’s REST APIs through Terraform.

This approach gives you:

AzAPI vs. azurerm: Feature Comparison (as of v4.5)

Module Implementation: Deploy Azure Managed Redis Today!

To bridge the gap, this Terraform module uses AzAPI under the hood while maintaining the same interface that future azurerm resources will use.

Example: Cluster and Database Definition

Example: Database with Persistence and Non-Clustered Mode

⚠️ Note:

Persistence and Non-Clustered only supported via AzAPI.

Non-Clustered: Limitations: ≤25 GB only

Reading Access Keys

AzAPI allows direct key retrieval through the List Keys API — no scripts needed:

Future-Proof Design: The use_azapi Switch

When azurerm adds full Managed Redis support, migration is effortless.

To migrate later:

1. Update the module
2. Set use_azapi = false
3. Run terraform plan
4. Apply — same inputs, same outputs, native provider

No state migration required.

Example Scenarios

The module includes six deployment examples:

• simple/ — Basic cluster setup
• high-availability/ — HA configuration for production
• with-modules/ — Redis modules showcase
• geo-replication/ — Cross-region replication
• enterprise-security/ — Customer Managed Keys, Managed Identity, Entra ID auth
• clusterless-with-persistence/ — Non-clustered mode with RDB + AOF persistence
