Kubernetes is an open-source platform for automating the deployment, scaling, and management of containerised applications. Created by Google and now maintained by CNCF, it's the industry standard for container orchestration. Kubernetes handles load balancing, auto-scaling, self-healing, and rolling updates — essential for running applications reliably at scale.
Key Points
- Automates deployment, scaling, and management of containers
- Self-healing: automatically restarts failed containers and reschedules workloads
- Managed services: EKS (AWS), GKE (Google Cloud), AKS (Azure) reduce operational burden
- Steep learning curve but industry-standard for production container workloads
Frequently Asked Questions
Probably not if you're a small team with a few services — Docker Compose or managed platforms (Railway, Render) are simpler. Kubernetes makes sense when: you have 10+ microservices, need auto-scaling for variable traffic, require zero-downtime deployments, or have a dedicated DevOps team. Most Indian startups don't need Kubernetes until they're well into scaling.
Basic concepts (pods, deployments, services): 1-2 weeks. Practical skills (configuring and managing clusters): 1-3 months. Advanced topics (networking, security, custom operators): 6+ months. Start with managed Kubernetes (GKE/EKS) rather than setting up clusters manually to focus on application deployment rather than infrastructure.
