An enterprise runs a mission-critical web application on Google Cloud Compute Engine and needs to implement an automated disaster recovery (DR) and traffic management strategy.
The design must meet the following operational requirements:
Which architecture should the enterprise deploy?
A Global External Application Load Balancer operating in Premium Tier provides a single Anycast IP address that terminates connections at Google Points of Presence (PoPs) closest to clients. Combined with Cloud DNS failover routing policies, organizations can achieve multi-tiered resilience by combining Layer 7 multi-region proximity routing with automated DNS-level fallback.
This architecture combines automated infrastructure-level traffic distribution with DNS-based disaster recovery steering. It eliminates manual intervention during regional disasters and delivers predictable business continuity within defined Recovery Time Objectives (RTO).
