Advanced Topic 41 of 51 Distributed Systems & Cloud
Kubernetes
Orchestrating containers across clusters.
How it works
Kubernetes is an open-source container orchestration platform that automates deployment, scaling and management of containerized applications across a cluster. The control plane, with an API server, etcd store, scheduler and controllers, maintains the desired state declared in YAML manifests: Pods group containers, Deployments manage replicas and rolling updates, Services provide stable networking and discovery, Ingress routes external traffic, and ConfigMaps and Secrets inject configuration. Autoscalers adjust replicas, and operators extend it with custom resources.
Where it is used
Running microservices, batch jobs and machine-learning workloads on cloud or on-premises clusters, with self-healing, rolling deployments and portable infrastructure, uses Kubernetes.
Common pitfall
It has a steep learning curve and operational overhead, and misconfigurations are common: missing resource requests and limits, no readiness probes, overly permissive RBAC and exposed dashboards. Stateful workloads need careful storage design. Complexity may exceed needs of small applications. Use managed services, GitOps, namespaces, network policies and monitoring, and start simple.
