⇒ Kubernetes (often abbreviated as K8s) is one of the most powerful container orchestration platforms used in modern cloud computing. It automates the deployment, scaling, and management of containerized applications, making it an essential tool for DevOps and cloud-native development.
This guide will walk you through Kubernetes from beginner to pro, explaining its fundamentals, history, importance, features, and architecture in an easy-to-understand yet detailed manner.
Before diving into Kubernetes, it's essential to understand some key concepts that will help you grasp its functionality better.
📌 Monolithic Applications – Traditional software applications where all components (UI, database, backend, etc.) are bundled together in a single package.
📌 Microservices Architecture – A modern approach to application development where software is broken down into smaller, loosely coupled services that communicate with each other.
📌 Kubernetes (K8s) – An open-source container management system that automates deployment, scaling, and operations of application containers.
📌 Project Seven – The internal project name Google used when developing Kubernetes.
📌 1980s – The era when container-based application isolation concepts were first explored.
📌 Numeronym (K8s) – The abbreviation "K8s" represents "Kubernetes," with the 8 letters in between replaced by the number 8.
✅ Container Management Tools – Platforms used to manage and orchestrate containers (e.g., Kubernetes, Docker Swarm).
✅ Docker Swarm – A native container orchestration tool by Docker that competes with Kubernetes.
✅ Scalability – The ability to increase or decrease computing resources based on demand.
✅ High Availability (HA) – Ensuring that applications remain available even if some components fail.
