Definition

Azure's GRS with read access enabled to the secondary region, allowing applications to read from either region. Provides higher availability for read operations during regional outages.

Real-World Example

Azure RA-GRS allows a global website to serve read requests from the secondary region when the primary region experiences an outage, maintaining 99.99% read availability.

Cloud Provider Equivalencies

These services offer data replication across multiple regions, allowing read access from secondary locations to enhance availability and resilience during outages.
