Episode 47 — Network Segmentation — VLAN, VXLAN, GENEVE, and Micro-Segmentation

This episode explains how network segmentation improves performance, security, and manageability in cloud architectures. We break down traditional VLANs for broadcast domain control, VXLAN for extending Layer 2 networks over Layer 3, and GENEVE as a flexible tunneling protocol for encapsulating network traffic. Micro-segmentation is also discussed, detailing how it enforces granular security policies between workloads.We also examine real-world cloud scenarios where segmentation prevents lateral movement by attackers and simplifies compliance audits. Understanding how to choose and implement the correct segmentation method is vital for Cloud+ exam scenarios involving network design and security optimization.
