VyOS is an open source network operating system Linux distribution based on Debian.
VyOS provides a free routing platform that competes directly with other commercially available solutions from well-known network providers. Because VyOS is run on standard amd64 systems, it can be used as a router and firewall platform for cloud deployments. VyOS can also be optimized to achieve routing at 100Gbps.
Besides being open-source, VyOS also offers subscription-based support, which includes pre-built images for cloud and virtual environments and LTS images for the 1.3 and 1.4 series.
