"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."
Cerf has been outspoken on the shift to IPv6, which will be one of many pressing tech topics to be tackled at Interop. One session will help attendees make the transition to IPv6, and the InteropNet, the temporary network that powers Interop, is emphasizing IPv6 technologies where possible.
"It's still a work in progress moving to IPv6," Heymann says. "A decade in progress and it will take another decade as well."
Interop is always a place for vendors to show off their new products, but tech industry spending has stagnated over the past few years, leading Heymann and other speakers to take a cautious tone at the conference. Heymann notes that Interop offers plenty of free programs, and says it's worth coming to Vegas for the conference even for those people who'd rather not pay the conference price. Tickets range from free (for the expo, keynotes, InteropNet tours and free sessions sponsored by vendors) to more than $3,000 for a full-price ticket.
Heymann says Interop organizers recognize the financial constraints faced by many in IT these days, and wants to reach anyone who can at least afford to make the trip to Vegas. Heymann expects about 13,000 attendees, about the same as last year.
But while many attendees will opt for the free portion of the show, the IT industry is possibly making a financial comeback. Gartner says iPads and other tablets will help drive worldwide IT spending up 5.6% in 2011, to $3.6 trillion.
