What is the most cost-effective method for delivering files from Azure Blob Storage to users in different geographical regions while ensuring users receive files from their local region?

Distributed File System (DFS)
read-access geo-redundant storage (RA-GRS)
Azure File Sync
geo-redundant storage (GRS)

The correct answer is: read-access geo-redundant storage (RA-GRS)

Using read-access geo-redundant storage (RA-GRS) is the most cost-effective method for delivering files from Azure Blob Storage to users across different geographical regions while ensuring they access files locally. RA-GRS not only provides redundancy and high availability by replicating the stored data to a secondary region but also allows read access to that replicated data in the event of a regional outage or for load-balancing purposes. This means that users who are closer to the secondary region can access the files from there, which minimizes latency and can lead to reduced costs associated with data transfer over long distances. RA-GRS is particularly advantageous because it doesn't entail the higher costs usually associated with duplicating and managing multiple storage accounts, while still maintaining the reliability and performance users require. This approach is tailored to support geo-distribution effectively, making it an optimal choice for scenarios that demand local access to content across wide geographical areas. The other options involve different mechanisms that either incur more costs or do not efficiently address the requirement of serving files from local regions.
