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. Google Cloud Storage Dual-region replicates across two regions (not zones) and is not a direct match. AWS does not offer a named, general-purpose storage redundancy tier that synchronously writes across three AZs within a single region for standard object storage. OCI Object Storage is regional and designed for high durability within a region, but it is not positioned as a 3-AZ synchronous replication tier equivalent to Azure ZRS.
