This video covers the core networking fundamentals every engineer needs to know - from basic IP addresses to advanced Kubernetes networking. We'll follow a simple approach: watch how one application grows from a single server to a complex cloud system, and learn each networking concept exactly when it becomes necessary.

▬▬▬▬▬▬ What You'll Learn ▬▬▬▬▬▬ 
→ IP addresses, DNS, ports, and network interfaces explained simply
→ How virtualization and VMs changed networking
→ Cloud networking: VPC, subnets, security groups, NAT Gateway (AWS)
→ How Docker networking works (bridge networks, overlay networks, port mapping)
→ Kubernetes networking deep dive: pods, CNI, services, Ingress, network policies

Networking is one of the most important — and most skipped — foundations for DevOps, cloud, and software engineers. In this video, I'll walk you through how networking actually works, from a single physical server all the way to containers and Kubernetes, using one practical real-world example the whole way through.

No dry theory. Just concepts that finally make sense.
