VyOS
VyOS is a fork of the now defunct Vyatta Core edition of routing software. VyOS is a Linux-based routing solution built on the Debian Linux distribution, and currently runs on x86 and x86-64 platforms.
VyOS provides a free and open source routing platform that competes directly with other commercially available solutions from well known network providers. Because VyOS runs on standard x86 systems, it is able to be used as a router and firewall platform for cloud deployments.
