Geo replication of PII data across Regions RRS feed

  • Question

  • Hi,

    Is there a way to securely replicate PII data across region? A scenario is that a user in Europe would update their profile and a user in Asia would see the updated information as soon as possible. Would Blob storage be the right location to store this information? While CDN can be used to replicate, what security measures need to be taken while replicating PII data?

  • Geo-redundant storage (GRS) is designed to provide at least 99.99999999999999% (16 9's) durability of objects over a given year by replicating your data to a secondary region that is hundreds of miles away from the primary region. If your storage account has GRS enabled, then your data is durable even in the case of a complete regional outage or a disaster in which the primary region is not recoverable.

    If you opt for GRS, you have two related options to choose from:

    • GRS replicates your data to another data center in a secondary region, but that data is available to be read only if Microsoft initiates a failover from the primary to secondary region.
    • Read-access geo-redundant storage (RA-GRS) is based on GRS. RA-GRS replicates your data to another data center in a secondary region, and also provides you with the option to read from the secondary region. With RA-GRS, you can read from the secondary regardless of whether Microsoft initiates a failover from the primary to the secondary.

    When you create a storage account, you select the primary region for the account. The paired secondary region is determined based on the primary region, and cannot be changed. For up-to-date information about regions supported by Azure, see Business continuity and disaster recovery (BCDR).

    Azure Content Delivery Network (CDN) is to cache content from Azure storage. Azure CDN offers developers a global solution for delivering high-bandwidth content. It can cache blobs and static content of compute instances at physical nodes in the United States, Europe, Asia, Australia, and South America.

    Could you elaborate more about your scenario of Replication data across the regions.

  • Just checking in if you have had a chance to see the previous response. We need the previously asked information to understand/investigate this issue further.
