Kubernetes
Kubernetes (often abbreviated as K8s) is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a framework for running distributed systems resiliently, handling tasks like load balancing, storage orchestration, and self-healing of containers. Originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF), it has become the de facto standard for container orchestration in cloud-native environments.
Developers should learn Kubernetes when building scalable, resilient microservices or cloud-native applications that require automated deployment, scaling, and management across clusters of machines. It is essential for DevOps and platform engineering roles, particularly in environments using Docker containers, as it simplifies operations like rolling updates, service discovery, and resource optimization. Use cases include deploying web applications, managing big data pipelines, and ensuring high availability in production systems.
