Azure storage option that maintains 3 synchronous copies of data within a single data center. The most cost-effective redundancy option trading regional protection for lower cost.
Azure LRS is used for temporary data or non-critical workloads where losing a single data center is acceptable, costing significantly less than geo-redundant options.
Azure LRS keeps three synchronous copies within one datacenter. Other clouds commonly replicate within a region across multiple zones/facilities by default, so the closest equivalents are single-region storage configurations without cross-region replication, but they may not match the 'single datacenter, 3 synchronous copies' behavior exactly.
