What is VXLAN and How It is Used as an Overlay Network in Kubernetes?

In this episode, we will learn what VXLAN is and how it can be leveraged as an overlay network to manage Kubernetes POD networks. We will start off by getting a crash course on the networking Open Systems Interconnect (OSI) model, followed by an overview of overlay networks. In the following section, we will discuss what VXLAN is and go over its architecture, encapsulation model, and how it can help segmented Kubernetes POD networks to communicate in a cluster. We will conclude the video by setting up a brand-new Kubernetes cluster leveraging Calico in VXLAN mode.
