summary
Walmart moves its POS into Kubernetes@Edge clusters so registers keep working during WAN outages, serving ~265 million customers weekly across ~11,000 stores; engineering claims a 250+ stores rolled out milestone. Store-specific data sync uses store-local Kafka with write‑forward to cloud and persistent data currently on VMware outside the cluster. Deployments use GitHub→CI pipelines, Helm charts, custom operators, Fluentd, Prometheus and a service mesh with Envoy sidecar failover to cloud for resiliency.
