Queue Storage and reliability
Azure Queue Storage is a service for storing large numbers of messages that you can access from anywhere in the world through authenticated calls using HTTP or HTTPS. Queues are commonly used to create a backlog of work to process asynchronously.
For more information about Queue Storage, reference What is Azure Queue Storage?
To understand how Azure Queue Storage helps maintain a reliable workload, reference the following topics:

Design considerations
Azure Queue Storage follows the SLA statements of the general Storage Account service.
Checklist
Have you configured Azure Queue Storage with reliability in mind?
- Since Storage Queues are a part of the Azure Storage service, refer to the Storage Accounts configuration checklist and recommendations for reliability.
- Ensure that for all clients accessing the storage account, implement a proper retry policy.
- Refer to the Storage guidance for specifics on data recovery for storage accounts.
- For an SLA increase, use geo-redundant storage.
- Use geo-zone-redundant storage (GZRS) or read-access geo-zone-redundant storage (RA-GZRS) for durability and protection against failover if an entire data center becomes unavailable.
Configuration recommendations
Consider the following recommendations to optimize reliability when configuring your Azure Queue Storage:
| Recommendation | Description |
|---|---|
| For an SLA increase, use geo-redundant storage. | Use geo-redundant storage with read access and configure the client application to fail over to secondary read endpoints if the primary endpoints fail to respond. This consideration should be part of the overall reliability strategy of your solution. |
| Use geo-zone-redundant storage (GZRS) or read-access geo-zone-redundant storage (RA-GZRS) for durability and protection against failover if an entire data center becomes unavailable. | For more information, reference Azure Storage redundancy. |
Source artifacts
To identify storage accounts using locally redundant storage (LRS), use the following query:
Resources
| where
type == 'microsoft.storage/storageaccounts'
and sku.name =~ 'Standard_LRS'
To identify storage accounts using V1 storage accounts, use the following query:
Resources
| where
type == 'microsoft.storage/storageaccounts'
and kind == 'Storage'
