A virtual network is a software-defined network that allows cloud resources such as VMs, containers, and load balancers to communicate securely. Virtual networks replicate traditional networking concepts—subnets, routing tables, firewalls—inside cloud environments. They enable private communication and control over traffic flow.
Why it matters
Virtual networks provide isolation, security, and flexibility in cloud architectures. They allow teams to design network topologies that match application needs without physical hardware. VPCs (Virtual Private Clouds) are the most common implementation.
Examples
Creating a virtual private cloud with public and private subnets or connecting services through a secure virtual network. Lessons on cloud fundamentals explain networking basics.
