The Promise of Plug-and-Go Virtualization

Demand for the stand-alone hypervisor product would depend on what the user's application needs were, Jaffe said, noting that the current approach of integrating the hypervisor as part of Linux worked fine for the conventional compute model, where there was a big system and a stack, and would continue to work fine there.

"But then, if you have something like the all-in-one appliance-like framework or any of the other different emerging models of computing, for that you sometimes want a tighter form factor that you can just plug it in and go. So we are trying to address these different market segments," Jaffe said.

While Novell believes that the target market for virtualization is "everyone," the appropriate form factor would differ based on whether the user was running a conventional stack, a tight appliance or a turnkey appliance that did not require all of the overhead and configurability, he said.

Asked to what extent or how Novell plans to make SLES 11, the next version of its server operating system, more roles-based, as Microsoft has done with Windows Server 2008, Jaffe said the way he looked at this was that there was the core operating system and the management system.

In the Linux world, and probably in the SUSE Linux Enterprise 11 time frame, the operating system itself would manage more core system resources and be less of an application manager, while the broader management system would be providing the other capabilities, he said.

"Do I agree with Microsoft that roles-based management is an important paradigm? Absolutely. But from a function placement perspective, I would put it more in the management system rather than in the operating system. With Microsoft's monolithic integrated approach, you sometimes can't cull that out separately," he said.

He was also Group Financial Communications Manager for First National Bank, the second largest banking group in South Africa before moving on to become Executive News Editor of Business Report, the largest daily financial newspaper in South Africa, owned by the global Independent Newspapers group.

He was responsible for a national reporting team of 20 based in four bureaus. He also edited and contributed to its weekly technology page, and launched a financial and technology radio service supplying daily news bulletins to the national broadcaster, the South African Broadcasting Corporation, which were then distributed to some 50 radio stations across the country.

He was then transferred to San Francisco as Business Report's U.S. Correspondent to cover Silicon Valley, trade and finance between the US, Europe and emerging markets like South Africa. After serving that role for more than two years, he joined eWeek as a Senior Editor, covering software platforms in August 2000.

He has comprehensively covered Microsoft and its Windows and .Net platforms, as well as the many legal challenges it has faced. He has also focused on Sun Microsystems and its Solaris operating environment, Java and Unix offerings. He covers developments in the open source community, particularly around the Linux kernel and the effects it will have on the enterprise.

He has written extensively about new products for the Linux and Unix platforms, the development of open standards and critically looked at the potential Linux has to offer an alternative operating system and platform to Windows, .Net and Unix-based solutions like Solaris.

His interviews with senior industry executives include Microsoft CEO Steve Ballmer, Linus Torvalds, the original developer of the Linux operating system, Sun CEO Scot McNealy, and Bill Zeitler, a senior vice president at IBM.
