What is Kubernetes?

Kubernetes, often abbreviated as K8s, is an open-source platform designed to automate deploying, scaling, and operating application containers. It groups containers that make up an application into logical units for easy management and discovery.

Why is Kubernetes Important?

Containers are a good way to bundle and run your applications. In a production environment, you need to manage the containers that run the applications and ensure that there is no downtime. Kubernetes provides you with the framework to run distributed systems resiliently.

Key Features of Kubernetes

  • Automated rollouts and rollbacks
  • Service discovery and load balancing
  • Storage orchestration
  • Self-healing
  • Secret and configuration management

How Does Kubernetes Work?

Kubernetes allows you to deploy cloud-native applications anywhere and manage them exactly as you like. It orchestrates computing, networking, and storage infrastructure on behalf of user workloads. This provides much of the simplicity of Platform as a Service (PaaS) with the flexibility of Infrastructure as a Service (IaaS), and enables portability across infrastructure providers.

Components of Kubernetes

Here are the main components of Kubernetes:

  • Pods: The smallest and simplest unit in the Kubernetes object model that you create or deploy.
  • Services: An abstract way to expose an application running on a set of Pods as a network service.
  • Volumes: A directory containing data, accessible to the containers in a pod.
  • Namespace: Intended for use in environments with many users spread across multiple teams, or projects.

Why Should Developers Use Kubernetes?

Kubernetes can significantly simplify the task of building, deploying, and maintaining distributed systems, providing a robust framework for running distributed systems resiliently, scaling them as necessary. It not only enables developers to build and deploy reliable and scalable applications, but also facilitates smooth operations and streamlined container management.


Overall, Kubernetes is a powerful, open-source platform that has become the industry standard for managing and orchestrating containers. Its ability to automate several manual processes related to deploying and scaling applications makes it an indispensable tool for developers, website administrators, and designers.
