How Kubernetes Uses VXLAN for Overlay Networking

Kubernetes needs to create a virtual network that connects pods across multiple nodes seamlessly. Since these pods reside in isolated networks, overlay networks—like those implemented with VXLAN—allow them to communicate over a physical Layer 3 infrastructure.

In this post, we explore how Kubernetes uses VXLAN to build an overlay network, enabling communication between pods across nodes.

1. What is an Overlay Network?

In Kubernetes, an overlay network abstracts the physical network, allowing pods on different nodes to communicate as if they were on the same Layer 2 network. VXLAN is one of the most popular protocols for building this overlay.

Introduction to Networking 101

Networking is a foundational component of modern technology, enabling communication between devices and systems. In this post, we will explore key networking concepts and provide the knowledge needed to understand how devices interact in a networked environment.

1. What is TCP/IP?

TCP/IP (Transmission Control Protocol/Internet Protocol) is the backbone of the internet and most local networks. It defines how data is broken into packets, transmitted, and reassembled at the destination.

Understanding VXLAN: Virtual Extensible LAN

Virtual Extensible LAN (VXLAN) is a network virtualization technology that helps extend Layer 2 networks over Layer 3 infrastructure. It’s a key enabler in modern data centers, especially in cloud environments, providing scalable overlay networks for virtual machines and containers.

1. What is VXLAN?

VXLAN is a network overlay protocol that allows you to create a virtual Layer 2 network over a physical Layer 3 network. It encapsulates Ethernet frames in UDP packets, enabling the deployment of virtual networks across large, distributed environments.
