Has Oracle replaced Microsoft as public enemy No. 1 when it comes to enterprise operating systems? Some in the OpenSolaris community believe so.

When your Linux server breaks, you'd better find someone who can fix it. Try some commercially supported distributions for those times when community forums just won't satisfy the corporate direction.

It's 2010, and you'd think server management would have reached new heights by now, but it hasn't -- Unless you've recently bought yourself a new pair of shoes.

A recent Accenture survey finds almost 40 percent of respondents planning to migrate mission-critical workloads to open source software within the next year. Will open source software overtake proprietary apps, and is there room for both in the marketplace?

There's no such thing as the perfect data center. There's always a data center management lesson to be learned. Try learning these 10 lessons -- the easy way.

The latest time line in fixing security vulnerabilities is a whopping 11.6 days. Why does it take vendors such a long time to recognize and detect new viruses, and is there anything you can do to protect your server OSes?

Anyone paying attention to Oracle's acquisition of Sun had a keen sense that a culture clash was inevitable for the open source software OpenSolaris. This week's launch of Illumos reveals the time might be now.

Server virtualization may have caught on far and wide, but the technology for securing virtual environments lags. Regaining visibility at the access layer is critical to keeping your data safe. Here are three ways to accomplish this.

The latest security research from Secunia shows security vulnerabilities among the major vendors increasing as much as fourfold in the past four years. Apple may think it stands apart, but its record is spotty, and with iPhone jailbreaks now 'legal,' its security woes may only be beginning.

With mainstream support now over for Windows Server 2003, it's time to evaluate your options. If you think you have good choices to replace the Windows OS, you might be in for a nasty surprise.

Myths about technology are often difficult to burst, and few are more trying than those concerning server virtualization.

The Unix server world was abuzz last week with IBM kicking off the public beta of AIX 7, and HP launching a no holds barred offense to persuade former Sun customers to abandon SPARC/Solaris environments in favor of Red Hat Enterprise Linux on ProLiant servers.

Microsoft gives the Russian Federal Security Service access to source code for Windows Server 2008 R2, Office 2010 and SQL Server, thus bringing the 'more eyeballs, more secure code' argument back to the surface. Only this time, it isn't about Windows vs. Linux. And that's not the only recent twist out of Redmond: Azure will come in more than one shade.

Linux server developers and adopters keep it real. A real choice for your data center, that is.

Microsoft is taking a page from SCO's playbook, suing Salesforce.com over nine CRM-related patents on which it claims the CRM vendor is infringing. Clearly, both companies believe cloud computing is critical to their future. With the cloud landscape still forming, is Microsoft prepared to do whatever it takes to be chief kingpin?

For many enterprises, the choice of a server OS is a difficult one. While many companies don't want to pay too much for an open source server, they also want their vendor to remain in business. Unfortunately, the current model seems both unsustainable and unchanging.

Finding your data center hotspots is one problem. Resolving them is another. Server virtualization may be part of the answer.

Are security issues holding your company back from deploying cloud computing? Asking key questions and trusting your intuition goes a long way in reducing the likelihood of security issues cropping up.

OS Roundup: When it comes to OS patches, Apple's model of 'ignorance is bliss,' is not the way to go; nor is Microsoft's regularly scheduled blitz. What is the best approach for both users and vendors?

How is the "other half" managing to lower costs in their data centers? They have a strategy. They might have more than one.

OS Roundup: Was it exclusion or exclusivity that fueled Apple's journey to being the world's biggest technology company? Or perhaps it's Apple's understanding and ability that when the producer names the tune, the consumer must dance.

If you believe that virtualization is limited to Web, application and a few other "lightweight" services, think again.

It's ironic -- Sun took great pains to license its open source OS, OpenSolaris, and with it ZFS, under the ostensibly home-grown CDDL license. Now, with the plug pulled on OpenSolaris, the future looks grim for the popular and highly regarded ZFS. Unless it can be absorbed into the Linux kernel that Sun carefully positioned it to avoid.

With better data center management, can one-tenth the price and one-tenth the power consumption deliver 10 times as much compute power? Lower the bar on runaway costs, false scalability promises and unchecked power consumption to find out.
