A short, but comprehensive tutorial to learn the Networking Basics.

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.

TechWorld with Nana

Networking fundamentals are explained through the evolution of a fictional travel booking website from a single server to a complex cloud system. The content covers IP addresses and DNS for device identification, ports for application routing, subnets and routing for network segmentation, firewalls for security, and NAT for private-to-public address translation. It then progresses to cloud concepts like VPCs, containerization with Docker including bridge and overlay networks, and Kubernetes orchestration with pods, services, and ingress. The core principle is that fundamental networking concepts remain constant across physical servers, cloud infrastructure, containers, and orchestration platforms, even as the tools evolve.

12 Networking Fundamentals Every Engineer Should Know

I never took the time to write down all those fundamentals and think about them. 
Now it’s done! ☺️ 
This is a good video for those who are not experts in networking and just do things without really understanding how it works. 
Thank you.
