Multi-Region Architecture

Design that deploys an application across two or more cloud regions for resilience to regional failure, lower global latency or data residency.

Definition

Multi-region architectures replicate data across regions and route users with global DNS or load balancing. They protect against region-wide outages and bring workloads closer to users but add cost, data consistency challenges and operational complexity.

Example

A media platform serves users from regions in North America, Europe and Asia, with Global Accelerator routing to the nearest.

Exam tip

Multi-AZ protects from data center failure; multi-region protects from regional failure and is required for regional DR.
