A retail company is expanding its digital storefront globally to accelerate market entry and support rapid user growth. The product strategy defines strict business continuity and resilience objectives for core transaction processing:
Which technical architecture aligns with the company's product strategy while fulfilling these business continuity objectives?
This architecture combines global traffic management via a global External Application Load Balancer, multi-region active compute deployments, and a globally distributed, synchronously replicated database using Cloud Spanner. It adheres to Google Cloud resilience best practices by ensuring that runtime request processing and automatic failover depend exclusively on the data plane rather than management plane APIs.
compute.instances.create or IAM policy propagation) during failover.Alternative architectures that rely on asynchronous replication or dynamic cold-standby provisioning fail both the zero-data-loss requirement and the sub-minute recovery timeline. Pre-allocated active capacity coupled with synchronous multi-region replication is the only pattern that fulfills these rigorous constraints.
