In the ever-evolving world of cloud computing and containerization, Kubernetes has emerged as the frontrunner in orchestrating containerized applications. As a Chief Architect with over two decades in the industry, I've witnessed firsthand the transformative impact Kubernetes has on application deployment and management. This article aims to demystify the complex world of Kubernetes networking, a critical component for the seamless operation of containerized applications.
