Run multiple virtual machines at once

It's nothing new that Intel-powered Macs have been running Mac OS X, Windows, and Linux for some time using Apple's Boot Camp. But one of the best utilities on the market for switching between operating systems lets you switch without a reboot.

Parallels Desktop allows you to switch seamlessly between operating systems without the need to reboot your Mac. Even better, regardless of which system you're running at the time, when you open a file type that's for another operating system, Parallels automatically recognizes the file type and makes the switch for you. Added support for … Read more

Living in a VM world

The big industry event about virtualization is VMworld, usually held in late Summer / early Fall. You don't have to wait for VMware's conference, however, to find yourself in VM World. We now live in it, every day.

It's really quite amazing how quickly virtualization has swept through, and become ensconced in, IT. Data centers have--for decades--been famously conservative when it comes to introducing changes that might threaten to disrupt production applications. For years, whenever we'd ask operationally focused IT managers about introducing new control software--for workload management, service provisioning, automated orchestration, and so on--we always heard … Read more

Free VPN service helps keep public Wi-Fi safe

The last time you used a public Wi-Fi hot spot, did you get the feeling you were being watched? Good. You very well may have been.

Just last week the U.S. Federal Trade Commission published the Wise Up About Wi-Fi page that offers tips for safe use of public Wi-Fi. Among the tips is the familiar advice to use encryption at all times (look for "https:" in the address header and the lock icon in the address bar or it the bottom status bar, depending on your browser).

The FTC's public-Wi-Fi safety page recommends that you … Read more

Network, don't fail me now!

Everything in IT depends on the network.--and not just in an abstract, "need it occasionally" sort of way. The packets must flow for virtually every operation, every job, every transaction. Whenever packets drop, or links go down, we're disconnected and isolated. Information doesn't flow; apps don't work; users don't proceed. We need the network up and running, millisecond by millisecond, every millisecond of every day.

Our utter, urgent dependency won't lessen in the coming years. It will intensify--redoubling and redoubling again. Cisco calls its vision of the future "together." HP … Read more

Database economics in cloud and virtualization

Many of the most interesting big economic landmarks in IT have happened around what might be called "re-platforming," as users take existing applications and redeploy them on new platforms, such as we see when applications move from corporate data centers to the Amazon Web Services EC2 or the Rackspace Cloud.

We see this trend every few years, for example when the IT masses switched from the mainframe to the client server world, and then again when we went from big iron Unix to Intel-driven X86 commodity platforms. Today, cloud and virtualization represent the next major re-platforming trend as … Read more

Avoiding the cost of entanglement

Modern IT is very focused on economics. We talk endlessly about cost. We debate capital costs vs. operational costs--CAPEX vs. OPEX, in the lingo. We look at Total Cost of Operations (TCO) and we try to calculate our projects' Return On Investment (ROI). But even with all of these economic metrics, we miss an enormous source of costs: Our long-term entanglement with the products, technologies, and approaches we choose.

Long ago, we had a bright idea. "We could represent the year portion of dates with just two digits--that would save space!" We happily did that for a few … Read more

Mix it up with Virtual DJ

Digital disc spinning has skyrocketed in popularity over the past five years and it's no wonder why. Compared with a full vinyl setup with all the hardware and physical media that requires, an MP3-based mixing station is extremely simple and cheap. There's even free software to get you started, and one of the most popular programs available is Virtual DJ.

The iPad gets joysticks

LAS VEGAS--Earlier today we heard about Fling, Ten One Design's latest attempt at giving the iPad a legitimate input device for gaming. Its tiny suction cups stick on to the surface of the iPad, giving you the closest thing to an actual button we've seen yet on an iPad.

A few hours later we're hearing about a much more traditional take on the situation, ThinkGeek's JoyStick-IT. The Joystick-IT accessory appears to work the same way as Fling, allowing users to center an actual chrome joystick wherever they see fit.

These two items are the first of … Read more

If virtual desktops great, why not used more?

Virtualization analyst Brian Madden asks an excellent question:

If VDI (virtual desktop infrastructure) is so great, then why aren't you using it?

It's a really good question, isn't it? Brian observes that however encouraged we are by the progress VDI has made, and however enthused we may be about extending the wins of server virtualization over into the desktop realm, we, personally, are not using desktop virtualization. You don't see analysts and developers doing so. And even the folks you meet from Citrix, Microsoft, Quest, VMware, and Wyse--the people selling VDI, for goodness' sake!--use traditional &… Read more
