Virtualization, cloud computing put new stress on network

Jon Brodkin, Network World | April 18, 2011
The network has long been king at Interop, the tech conference that will be celebrating its 25th anniversary in 2011. But networking "has fallen behind" over the past couple of years as a new emphasis on cloud computing and virtualization has taken hold, says Interop general manager Lenny Heymann. But now it's time to put the focus back on the network.

The network has long been king at Interop, the tech conference that will be celebrating its 25th anniversary in 2011. But networking "has fallen behind" over the past couple of years as a new emphasis on cloud computing and virtualization has taken hold, says Interop general manager Lenny Heymann. But now it's time to put the focus back on the network.

"In the last couple years it does seem a lot of other areas have surged ahead and networking has fallen behind," Heymann says. Networks have become more stable over the years, and innovation head in different directions such as cloud computing and virtualization, Heymann said. But networks, far from becoming irrelevant, have to be rock-solid to take advantage of new technologies.

"We need to look at how networks respond to some of these changes that have really swept through the market," Heymann says. "There were changes in the data center around cloud computing and virtualization that have put pressure on networks and there are some changes that need to be made."

Because of virtualization technologies like live migration, virtual machines can move around the data center at warp speed, but the ability to manage the network and servers "is lagging the speed at which the VMs can be moved from one machine to another," Heymann says. "Management of network has to be speedier, more efficient and automated to keep up."

And while cloud computing lets IT shops offload applications and processing power to vendor-hosted networks, customers must integrate their own networks with those hosted by the cloud vendors and make sure they can handle the new traffic originating from outside their own networks. Vendors like F5 and Riverbed have been making progress in ensuring that performance doesn't suffer when customers connect to the cloud, Heymann says.

Quiz: Can you identify the misfires, milestones and high jinks from Interops past?

"When you could control it from end to end you could control performance better," he says. "Different issues get involved when you're pulling data out of public cloud data centers."

Interop was started 25 years ago to spur vendors to demonstrate that their products could work together. "Everything's plugged together today, but that wasn't the case 25 years ago," Heymann says.

Interop Las Vegas will be held May 8-12 at the Mandalay Bay conference center. The conference will begin with two days of workshops on cloud computing and virtualization, and a two-day CIO Bootcamp.

Then on Tuesday morning, Google's Vint Cerf, a tech luminary who helped create the Internet, will take the keynote stage and be interviewed by Interop founder Dan Lynch. Cerf is not only a builder and thought leader for the tech industry, but he's also inside one of the planet's biggest users of technology at Google, Heymann notes. "Vint is in a really unique position."
