Virtual Networking Explained: Firewalls, Routers, Switches & vNICs
Virtual networking is a core concept in cloud computing and modern IT infrastructure. In this video, we break down virtual firewalls, virtual routers, virtual switches, and virtual network interfaces (vNICs) using clear diagrams and real-world examples.
You’ll learn:
🔥 How a virtual firewall protects cloud traffic using security rules
🌐 What a virtual router does and how traffic flows to the cloud
🔀 How virtual switches (vSwitch) connect VLANs and virtual machines
🧩 What vNICs are and how they act like physical network cards
☁️ How all these components work together in a cloud environment
