About
Kubernetes (K8s) is an open-source container orchestration system originally designed at Google and now maintained by the Cloud Native Computing Foundation (CNCF). It automates the deployment, scaling, and management of containerised workloads across a cluster of machines.
The fundamental unit is the Pod — one or more containers that share networking and storage and are scheduled together. Deployments manage replicated pods, handle rolling updates, and roll back automatically if health checks fail. Services provide stable DNS names and load-balanced virtual IPs for reaching pods regardless of which node they run on. ConfigMaps and Secrets inject configuration without baking it into images.
Horizontal Pod Autoscaler adjusts replica counts based on CPU, memory, or custom metrics. Persistent Volumes decouple storage from pod lifecycle. The control plane (API server, scheduler, etcd, controller manager) runs separately from the worker nodes it manages. All major cloud providers offer managed Kubernetes: GKE (Google), EKS (AWS), AKS (Azure), each handling control plane patching and upgrades.
Key Features
- Automated rollout and rollback
- Service discovery and load balancing
- Self-healing capabilities
- Horizontal scaling and autoscaling
- Secret and configuration management
- Storage orchestration

- Extensible architecture with CRDs
Pros
- Industry standard for container orchestration
- Cloud-agnostic (works on AWS, GCP, Azure, on-prem)
- Highly scalable and resilient
- Large ecosystem and community support
- Declarative configuration (GitOps)
- Rich extension ecosystem (operators, Helm charts)
Cons
- Steep learning curve
- Complex setup and maintenance
- Resource-intensive for small deployments
- Overkill for simple applications
- Requires dedicated operations team at scale
