☸️ Kubernetes Overview

Kubernetes (K8s) is an open-source platform designed to automate the deployment, management, and scalability of containerized applications. Originally created by Google and currently maintained by the Cloud Native Computing Foundation (CNCF), it has become the market standard for container orchestration.

🔑 Key Concepts​

  • Cluster: a set of nodes (machines) running containerized applications.
  • Node: a machine (physical or virtual) running Kubernetes services.
  • Pod: the smallest executable unit in Kubernetes, usually representing one or more containers.
  • Service: a resource that exposes applications in pods in a stable way, even if pods change IP addresses.
  • Ingress: controls external access to services, usually via HTTP/HTTPS.
  • ConfigMap and Secret: used to manage configuration variables and sensitive data.
  • Deployment: a resource that manages pod replicas and updates.

⚙️ Benefits of Kubernetes​

  • Automatic scalability of applications.
  • High availability with load balancing.
  • Simplified management of updates and rollbacks.
  • Portability across different cloud providers or on-premises infrastructure.
  • Rich ecosystem, with support for various monitoring, CI/CD, and security tools.

📊 Use Cases​

  • Hosting microservices.
  • SaaS platforms with high demand.
  • Large-scale data processing.
  • Hybrid and multi-cloud environments.
