Network virtualization for dummies

What is network virtualization and how does it work? Don't worry, you don't have to be a tech whiz to understand it. Network virtualization is basically the creation of a virtual version of a physical network. This virtual network operates on software and allows for the separation of the physical network and its services from the application or service providers that use it.


With network virtualization, you can have multiple networks running on top of a single physical infrastructure. This means you can have different organizations, departments, or even individuals with their own specific network requirements running on the same physical network. Each virtual network can have its own security, routing, and quality of service policies.


One of the key benefits of network virtualization is that it allows for better utilization of network resources. Instead of dedicating physical infrastructure to each network, virtualization allows you to allocate resources dynamically based on need. This increases efficiency and reduces costs.


Another benefit is that network virtualization makes it easier to move workloads between physical networks. Because the virtual networks are decoupled from the underlying physical infrastructure, the workloads can be moved with minimal disruption to the network.


In summary, network virtualization allows for the creation of multiple virtual networks that operate independently of the physical infrastructure. This increases efficiency, reduces costs, and makes it easier to manage and move workloads between networks.
