Statefulsets on Kubernetes: The Guardians of Your Data Galaxy
summary
Argues that Kubernetes can run production databases by combining StatefulSets for stable network identities and ordered lifecycle, PVs for durable data and storage classes to automate provisioning, and shows patterns like per-team micro‑databases (largest cited deployment ~15 TB persistent volumes). Describes autoscaling by adding nodes for seasonal peaks (Black Friday), emitting lifecycle events for coordinated failover, and using virtual application networks such as Linkerd/Scupper plus CockroachDB geo‑pinning for multicluster/geo compliance. Results presented as feasible and in use.
