  • 7 half-truths about virtualization

    Virtualization is revolutionizing the data center, mostly for the better. But no technology is without potential pitfalls. Problems related to management, security, ROI and power use can all trip up a virtualization deployment that isn't planned properly.

  • Busting the nine myths of cloud computing

    Wherever you turn, someone's ready to tell (or sell) you something related to cloud computing. Cutting through the myths is essential to deciding whether, when, and how the cloud is right for you. Here's our top list of myths; we welcome your suggestions and feedback in our cloud myths discussion area**URL TK**:

  • Server Virtualization: Top Five Security Concerns

    In surveys of senior-level IT managers, security is consistently one of the top five concerns, along, specifically, with security related to the hot technology of the moment. Most recently those worries have included social-networking technologies such as Twitter and Facebook and other outlets through which employees could turn loose company confidential data. But the security of virtual servers and virtualized infrastructures also rank near the top of the list-and rightly so, according to analysts.

  • Best Practices for Reaping Benefits of Virtualization

    Despite the broad adoption of server virtualization, many firms still struggle with the technical and organizational changes that virtualization brings. We see IT shops facing three major challenges: getting business and executive buy-in, motivating application owners to move to virtual machines, and restructuring the IT team to achieve maximum efficiency in a virtualized environment.

  • VMware vSphere: Does It Solve IT's Biggest Worries About Cloud?

    For all the hype about cloud computing in the enterprise—hype that Gartner believes is now nearing its peak—IT professionals continue to tell cloud-related vendors that the cloud will not be practical until several serious concerns are addressed. VMware, with its vSphere 4 announcement today, is laying the foundation for what it hopes will be a central role for VMware technology in enterprises making use of both public and private cloud computing systems.

  • Windows 'XP mode': The new DOS box

    An October surprise -- that's how many are interpreting Microsoft's 11th-hour revelation that it will be providing a virtualized copy of Windows XP as a free compatibility add-on to Windows 7 Professional, Ultimate, and Enterprise editions.

  • Desktop Virtualization and Licensing: IT Wary of Gotchas

    CIO Roxanne Reynolds-Lair of The Fashion Institute of Design and Merchandising wanted to bring both Macs and Windows to her college's students, administrative employees and teachers. She bought a MacBook Pro and tested new-fangled desktop virtualization software that allows her to run both Windows and OS X on a single machine.

  • How Virtualization Improves Software Development

    Virtualization technologies aren't just for server consolidation. They've long been valuable tools to anyone writing or testing software. We show how these tools are being used for software development and quality assurance now and identify a few places where developers still want more from virtualization.

  • Virtualisation: Taking the risk

    Securing virtual environments, whether it be at the desktop, server, network, application or storage level, is a crucial component to any virtual strategy. With the security threat landscape constantly evolving, putting all company resources into a centralised virtual environment without a comprehensive security game plan is a gamble no organisation should willingly take.

  • Virtualization a challenge for IP contact centers

    IP contact centers can benefit from virtualization as much as any other technology, but because of the real-time nature and need for reliability, deploying virtual machines in this environment requires care in selection of hardware, segmentation of applications and the use of replicating virtual machines on the fly.

  • The tricky math of server virtualization ROI

    Server virtualization is supposed to save buckets of cash, largely from server reduction. After all, consolidating some 20 physical servers to three host servers means less hardware, power and cooling, and management overhead.
