Kubernetes

Kubernetes, often abbreviated as K8s, is an open-source platform designed for automating the deployment, scaling, and management of containerized applications. It enables developers and operations teams to manage complex applications with high availability, resilience, and scalability.

Key Concepts

• Containers and Orchestration
  While Docker manages individual containers, Kubernetes orchestrates multiple containers across a cluster of machines, automating tasks like scaling, networking, and health management.

• Pods
  A Pod is the smallest deployable unit in Kubernetes, consisting of one or more containers that share storage, networking, and specifications. Pods ensure containers are grouped and managed as a single entity.

• Nodes and Clusters
  A Kubernetes cluster consists of multiple nodes, with each node representing a physical or virtual machine that runs containerized applications. Clusters provide reliability by distributing workloads across multiple nodes.

• Services and Networking
  Kubernetes services enable communication between Pods, other applications, and users. These services abstract networking and load balancing, allowing Pods to connect reliably.

• Scaling and Self-Healing
  Kubernetes automates scaling based on demand and can restart failed containers, ensuring that applications remain available and responsive. Its self-healing capabilities make it ideal for managing large, distributed applications.

Why Use Kubernetes?

Kubernetes simplifies the management of containerized applications in production environments. Its features enable applications to be resilient, scalable, and highly available, making it a vital tool in modern DevOps workflows and cloud-native applications.
