Azure storage option that synchronously replicates data across 3 availability zones in a region. Protects against data center failures while keeping data within regional boundaries.
Azure ZRS ensures your application data survives entire data center outages while meeting data residency requirements for EU customers.
Azure ZRS synchronously replicates data across three Availability Zones within one Azure region. AWS and GCP don’t offer a single, universal 'ZRS' label across all storage types: S3 is designed for multi-AZ durability within a region, while EBS offers Multi-AZ for certain volumes. GCP’s closest commonly used option for higher availability across locations is Dual-region (replication across two regions, not zones). OCI Object Storage is regional by design; higher availability is typically achieved via replication policies (often across availability domains or regions depending on service and region capabilities).
