What is Kubernetes? Nedir?
Kubernetes (K8s) is an open-source orchestration platform that automates the deployment, scaling, and management of containerized applications.
Kubernetes was developed by Google in 2014, inspired by their internal Borg system, and donated to the Cloud Native Computing Foundation (CNCF). Named from the Greek word for 'helmsman,' Kubernetes is the de facto standard for container orchestration. Kubernetes provides abstractions like Pods (container groups), Deployments, Services (network access), Ingress (external traffic management), ConfigMaps and Secrets, and PersistentVolumes. Auto-scaling (HPA), self-healing, rolling updates, and rollback capabilities ensure reliable deployment. The Kubernetes ecosystem is extremely rich: Helm (package management), Istio (service mesh), Prometheus (monitoring), ArgoCD (GitOps), Cert-Manager (certificates), and Nginx Ingress Controller. All major cloud providers offer managed Kubernetes services (EKS, AKS, GKE). Spotify, Airbnb, Pinterest, The New York Times, and Adidas use Kubernetes infrastructure. It has become the fundamental platform for cloud-native application development.
