eBay Geo-Distributed Database on Kubernetes [A]

on YouTube ↗35m

" summary

eBay runs a geo-distributed document DB on Kubernetes with thousands of storage engines, using a local volume plugin that exposes bare-metal SSDs as PV/PVCs and a scheduler-side PV/PVC bonding to enforce volume-level anti-affinity. Performance class offers ~50K IOPS and up to 500 MB/s; standard class ~300 IOPS/300 MB/s. Local SSD 4KB writes measure ~200 ns vs ~1,800 ns on iSCSI. Cross-cluster pods get global IPs for replication, and snapshots send deltas to remote volumes via a workflow-driven control layer.
