To deploy resource that pass this rule:

  • Create resources of type Microsoft.Cache/redisEnterprise and an Azure Managed Redis SKU, such as:
    • Balanced_*
    • MemoryOptimized_*
    • ComputeOptimized_*

For example:

Azure Bicep snippet
resource primary 'Microsoft.Cache/redisEnterprise@2025-07-01' = {
  name: name
  location: location
  properties: {
    highAvailability: 'Enabled'
    publicNetworkAccess: 'Disabled'
  }
  sku: {
    name: 'Balanced_B10'
  }
}

Configure with Azure template#

To deploy resource that pass this rule:

  • Create resources of type Microsoft.Cache/redisEnterprise and an Azure Managed Redis SKU, such as:
    • Balanced_*
    • MemoryOptimized_*
    • ComputeOptimized_*

For example:

Azure Template snippet
{
  "type": "Microsoft.Cache/redisEnterprise",
  "apiVersion": "2025-07-01",
  "name": "[parameters('name')]",
  "location": "[parameters('location')]",
  "properties": {
    "highAvailability": "Enabled",
    "publicNetworkAccess": "Disabled"
  },
  "sku": {
    "name": "Balanced_B10"
