Virtualization: Not just for machines anymore

Virtualization quickly went from buzzword to standard tool for developer and ops staff alike. But its cousin, the virtualized network, has taken a little longer to come of age and become popular. But now that cloud hosting has become commonplace, virtualizing the network connections between cloud-hosted servers has become a fashionable way to speed up performance and increase security.

Vyatta, for all intents and purposes, created the network virtualization market single-handedly, starting in 2006. Kelly Herrell, CEO of Vyatta, said that his company focused on layer 2 and 3 networking, rather than sitting higher on the transaction layer totem pole. He said this was the secret to Vyatta's success.

“Nobody tried to come at this layer 3 networking problem before,” he said. “The only way you did this was with proprietary Cisco routers. We had a lot to prove, and our community helped us prove that thanks to our free download. Layer 3 is a very important thing, so layer 2 and 3 are the network. Layers 4 through 7 make the network better, and they're where you'll do load balancing, WAN optimization and firewalling, but layer 2 and 3 are your fundamental networking layers.

“Cisco had 90% market-share when we started, and they got that through proprietary protocols. The Internet has removed that need, so you can start to use a vendor of heterogeneous networks. That was the beginnings of a long decline toward standardization.”

Vyatta's product, at the start, was a Linux distribution that, essentially, is a router. The company’s software includes all the complex capabilities an expensive router contains: load balancing, firewalling, WAN optimization, NAT, DHCP server, and a host of other network-focused services that allow developers and ops people to configure and deploy Vyatta-based routers into any cloud environment. The company has since expanded and refined its product line.

“One of the things we see as the core factor for adoption is literally the application storm that’s going on,” said Herrell. “Looking back on it, it's probably driven by the fact that people have fairly unfettered access to software development tools. Not too long ago it was negotiations, receipts and purchases, but now you just download things online. There's a storm of application deployment going on. From an IT side, they're responsible for getting the gear to run, and creating large generic pools of virtualized compute to put the applications on.”
