Why this architecture works

  • Front Door performs global anycast routing with health probes, failing over between regions in seconds
  • Active-active regions double as capacity headroom instead of paying for idle standby
  • Geo-replicated SQL keeps RPO near zero and enables regional read scale-out
  • Shared Redis session cache keeps user sessions sticky-free so any region can serve any request
  • Centralized Log Analytics workspace correlates telemetry from both regions in one place
