Virtual Networking
Virtual networking is a technology that creates logically isolated networks on top of physical network infrastructure, enabling the abstraction and segmentation of network resources. It allows organizations to build, manage, and secure networks in software-defined environments, independent of underlying hardware. This concept is fundamental in cloud computing, data centers, and virtualization platforms for creating flexible, scalable network architectures.
Developers should learn virtual networking when working with cloud platforms (like AWS, Azure, or GCP), container orchestration (such as Kubernetes), or virtualization technologies (like VMware) to deploy and manage applications in isolated environments. It's essential for implementing network security, microservices architectures, and hybrid cloud setups, as it enables features like virtual private clouds (VPCs), subnets, and network policies without physical hardware constraints.
