Lesson Learnt Running an Indian Bank on Kubernetes
summary
A production-grade Kubernetes platform runs an Indian bank on prem since April 2019, built and operated by a three‑person platform team for ~10 developers and ~50 nodes across prod/non‑prod/DR, targeting 5,000 TPS. It uses KubeSpray/kubeadm for installs, Istio service mesh for east‑west governance, Prometheus + Grafana and Zipkin for observability, Helm charts for installs, and MinIO/NFS for object/storage; storage orchestration and Istio TLS/config cause the most outages, but the platform ships apps successfully after tight IT governance.
