Resilient Multiregion Global Control Planes With Crossplane and K8gb
Talkat KubeCon + CloudNativeCon China 2025 · on Wednesday, 2025-06-11· at 11:00· Level 19 | Crystal Court I·
summary
Reference architecture that combines Crossplane and k8gb to run a true active/ passive global control plane, using k8gb to monitor ingresses and update centralized DNS (Route53/Azure or RFC2136) and Crossplane functions (KCL) to flip resource management policies between manage and observe on status changes. Demo deploys identical specs to two clusters (China and Europe), successfully steers traffic on failure and back on recovery, with small demo glitches but core failover works; DNS TTL (30s–2min tradeoff) limits switchover speed.
