Kubernetes Basics: Understanding Pods, Deployments, and Services

This comprehensive guide compares traditional VM-based application deployment with Kubernetes, demonstrating how to evolve from running a single Python web app instance to a scalable, highly available service. It covers essential concepts like reverse proxies, load balancing, replication, and failure recovery using both traditional infrastructure and Kubernetes primitives (Pods, Deployments, Services). The tutorial includes practical examples showing how Kubernetes automates many manual deployment tasks while following the same underlying patterns used in traditional infrastructure.
