Jeff Klink, Sera4 | KubeCon + CloudNativeCon Europe 2020 – Virtual
summary
Company builds Bluetooth enterprise locks that use asymmetric cryptography and support offline access, and migrates backend from VMs to Kubernetes (Rancher/RKE, kubectl, Helm, Terraform). Migration targets identity (SSO), proxies/ingress and microservices so rolling orders jump from ~1,000 to 8,000 locks without global outages. Pain points: etcd resilience, control-plane placement and latency across regions; solution: hub-and-spoke clusters, Anycast ingress and moving certificates/keys toward the edge. Result: faster rollouts, stronger compliance and measurable latency improvements.
