How to connect Azure Blob storage to VM's in 2 different regions

Question

Hi Team,

We had Prod and DR environment in 2 different regions we need to use 7TB of blob storage for content storage. Blob is created in PRD region how can we attach same BLOB to DR whenever DR-Drill or Prod failover is happening. please give options to archive this scenario.

Answer 1

Enabling access to virtual networks in other regions is in preview currently- Refer this document for more details.

To enable access from a virtual network that is located in another region over service endpoints, register the AllowGlobalTagsForStorage feature in the subscription of the virtual network. All the subnets in the subscription that has the AllowedGlobalTagsForStorage feature enabled will no longer use a public IP address to communicate with any storage account. Instead, all the traffic from these subnets to storage accounts will use a private IP address as a source IP. As a result, any storage accounts that use IP network rules to permit traffic from those subnets will no longer have an effect.

Does this help? Please let me know if you have any further questions/concerns and we will be glad to assist you further. Thank you!

Hi @Venkata Sai Kalyan , typically for DR (Disaster Recovery) purpose, you would want to have storage with your copy of data in the DR region, to continue your service when the Prod region is unavailable. What exactly is the storage account type you are using? If it's General purpose v2 Blob storage, you can utilize built-in capability of RA-GRS (read-access geo-redundant storage).
