Kubernetes (K8s) is an open-source container orchestration platform originally developed by Google and donated to the Cloud Native Computing Foundation (CNCF) in 2014. It has become the de facto standard for running containerised workloads at scale in production environments.
At its core, Kubernetes solves the problem of running many containerised applications across many servers reliably — ensuring applications are always running, self-healing when they fail, scaling up when demand increases, and rolling out updates without downtime.
Core Kubernetes concepts
A Pod is the smallest deployable unit in Kubernetes — typically one container, sometimes a group of tightly coupled containers. A Deployment manages a set of identical Pods, ensuring the right number are running and handling rolling updates. A Service provides a stable network identity for a group of Pods. A Namespace creates a logical boundary within a cluster, used for multi-tenancy and resource isolation. A Node is a server (physical or virtual) that runs Pods.
Why Kubernetes matters for enterprise on-premise deployments
For enterprises running workloads on their own hardware, Kubernetes provides cloud-like operational capabilities — automated scheduling, health checks, horizontal scaling, rolling deployments, and declarative configuration — without requiring a public cloud provider. This is the fundamental enabler of on-premise PaaS: you get the operational benefits of a cloud platform, on hardware you own.
The complexity, however, is real. A production Kubernetes deployment requires expertise in networking (CNI plugins, ingress controllers, network policies), storage (CSI drivers, persistent volumes), security (RBAC, admission controllers, pod security standards), observability (metrics, logs, traces), and upgrade management. This is why platforms like AravaliStack exist — to deliver managed Kubernetes as part of a complete platform rather than requiring each enterprise to assemble and operate it independently.
Kubernetes in India's regulated sectors
Kubernetes is widely used in Indian banking, insurance, and healthcare technology — but almost always managed by the IT team as a raw infrastructure component rather than as part of a governed platform. This creates significant operational risk: there is no separation between the platform team and application teams, security configurations are inconsistent, and compliance posture is difficult to audit. A platform layer above Kubernetes — with enforced network policies, admission controls, namespace isolation, and GitOps governance — is required for RBI and SEBI compliance.
