Introduction to Kubernetes

Kubernetes, often referred to as K8s, is a powerful open-source platform that has become the cornerstone of modern cloud computing. It automates the deployment, scaling, and management of containerized applications, allowing businesses to focus on innovation rather than infrastructure. Originally developed by Google, Kubernetes is now maintained by the Cloud Native Computing Foundation (CNCF) and has a vibrant community contributing to its continuous evolution.

Kubernetes supports a wide range of architectures, from on-premises data centers to public clouds, making it a versatile choice for organizations of all sizes. Its ability to manage complex applications efficiently is why it’s considered a must-have skill for IT professionals today. This guide is designed to help you navigate the Kubernetes landscape, whether you’re just starting or looking to deepen your expertise.
