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.

One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
