Virtualization saves money — or so we’re told. But how much does it save (if any) and how do we calculate the true costs? Paul Rubens discusses the thorny issue. Working out how much virtualization is going to cost you has always been tricky, and it’s certainly not getting any easier. For example, VMware made […]

VMware has clearly held the top spot in the burgeoning virtualization market, running ahead of competitors Citrix and Microsoft. Yet the race appears to be shifting, reports Paul Rubens. “What, me worry?” is the signature phrase of Mad Magazine’s Alfred E. Neuman. It probably also sums up VMware’s reaction to Gartner’s latest assessment of the […]

Hackers have a nefarious technology — Permanent Denial of Service (PDoS) attacks — that can cripple your servers for good. Paul Rubens reports. Stuxnet-style malware that attacks computer hardware could put your company out of business by physically destroying the servers, networking equipment and storage resources in your data center. Unlike Stuxnet, however, this type […]

Many IT departments embrace virtualization as a cost-saving technique, yet they hesitate to deploy it for their company’s truly core applications. Paul Rubens discusses VMware’s take on the issue.

Why would anyone use Red Hat Enterprise Virtualization (RHEV) instead of VMware’s or Microsoft’s virtualization technologies? Talk to Navin Thadani, Red Hat’s senior director, virtualization, and he’ll tell you that RHEV’s attractions […]

Apple is famously possessive about its Mac OS X operating system, even going so far as to forbid the virtualization of the desktop version of OS X in its EULA. Paul Rubens discusses an intriguing (though perhaps not likely) exception to this rule. VMware’s vSphere 5 virtualization platform is due to be released some time […]

Virtualization management systems are causing some grumbles among IT managers, according to a recent survey. Paul Rubens discusses the issue. Virtualization has run far ahead of the management systems most enterprises use to control their IT environments. That’s a problem because this lack of control means many enterprises can’t unleash the full potential of server […]

Virtualization has come a long way in the last few years, now creating a market for virtualization security. As vendors spy an opportunity, which firms are the market leaders? Paul Rubens reports. Which firms are the leaders in virtualized infrastructure security? There’s no obvious answer to this question because, as yet, no real market leaders […]

When your product can be freely and legally copied by competitors, how do you compete in the marketplace? Paul Rubens talks about Red Hat’s latest strategic moves. Red Hat Red (NYSE: RHT) has gotten fed up with what it sees as companies like Oracle and Novell sidling up to its Linux server operating system customers […]
