param storageAccountNames array = ['account1', 'account2', 'account3']
resource storageAccounts 'Microsoft.Storage/storageAccounts@2021-04-01' = [
  for name in storageAccountNames : {
    name: name
    location: 'westus'
    sku: {
      name: 'Standard_LRS'
    }
    kind: 'StorageV2'
  }
]

Tip: Split your code into modules. This helps you manage and reuse your deployments.

Challenges and Improvements

Current Limitations

You might see some limits when you use Bicep. Bicep is a clear layer over ARM templates. It works with all ARM resource types and API versions. Sometimes, type information is missing. You can still deploy resources, but you may not see every detail. Bicep only works with Azure resources from ARM APIs. You cannot use it for things outside Azure or for regular programming.

Some advanced features are not ready in Bicep yet. Defender for Storage settings are missing in some cases. Some storage accounts and blob types do not scan for malware. Some Azure regions do not have this feature. If you use client-side encryption, Bicep cannot scan those blobs. It cannot decrypt them. Event Grid topics without public network access do not get malware scanning.

• You cannot set some Defender for Storage advanced settings.

• Old v1 storage accounts do not scan for malware.

• Azure Files service does not scan for malware.

• Blobs with NFS 3.0 are not scanned.

• Some regions do not support malware scanning.

• Append and Page blob types are not scanned.

• Client-side encrypted blobs cannot be scanned.

• Index tag scan results are not supported in accounts with hierarchical namespace.

• Event Grid topics without public network access are not scanned.

These limits mean you must plan your deployments well. You need to think about which region and resource type to use. You should also think about security needs. You can make things more reliable by using redundancy, autoscaling, and monitoring. You should use best practices like automated testing and version control to keep your deployments strong.

Note: Physical hardware limits in Azure regions can slow down resource creation when it is busy. You can avoid problems by using paired regions and availability zones.
