Virtual Networks
Virtual Networks are software-defined network overlays that abstract physical network infrastructure to create isolated, logically segmented networks. They enable secure communication between resources like virtual machines, containers, and services, often across cloud or hybrid environments. This technology provides features such as IP address management, routing, and network security policies without requiring physical hardware changes.
Developers should learn Virtual Networks to design scalable, secure architectures in cloud platforms like AWS, Azure, or Google Cloud, where they are essential for isolating workloads and managing network traffic. They are crucial for implementing microservices, multi-tier applications, and hybrid cloud setups, as they allow fine-grained control over connectivity and security, reducing reliance on physical network configurations.
