Native network segmentation for virtualization workloads

This blog post discusses how to implement native network segmentation for virtualization workloads in Red Hat OpenShift using the new User Defined Network (UDN) feature. The article highlights motivations for isolating networks, challenges faced due to Kubernetes' existing networking model, and various use cases for UDNs, including namespace isolation and interconnected network configurations. It also covers the seamless migration of VMs, integration with Kubernetes policies, and egress capabilities. The post concludes with a practical demonstration of deploying workloads and configuring networking features, aiming to improve stability and management of IP addresses without relying on NAT.
