Some vendors in hardware-based routing and security are tying services to virtual switches or providing firewall-only virtual machines, both of which represent a continuation of the sort of vendor lock that many organizations are hoping the cloud will break. This doesnt just fall short of meeting cloud network architecture requirements (on-demand, elastic, mobile, platform neutral, limited footprint), but it also limits cloud developers ability to properly protect virtual machines and users in a multi-tenant environment.
What they Do: The platform-independent Vyatta Network OS virtual machine is a bridging, routing and network security (firewall, IPS, IPSec & SSL VPN, web filtering+, layer 2 cloud bridging) solution for cloud computing platforms. Vyatta addresses the complex automation, migration and advanced security needs of hosted public cloud data and centralized private clouds by enabling cloud architects to design complete n-tier networks within a hypervisor environment. Vyattas solution is delivered on-demand and can be used on a per-customer or per-server basis.
