Virtualization technology is delivering on its promise of creating a more energy-efficient and cost-effective data center. However, there's plenty of room to improve the technology, especially as IT enters the cloud computing era.
funny thing happened on the way to virtualization: Many IT managers discovered
that instead of bringing simplicity to their busy data centers, the technology actually
made things more complicated. Sure, physical server counts were reduced, energy
costs lowered and hardware footprints shrank-all thanks to virtualization.
complexity and confusion grew, and managing virtual environments became an
almost unbearable challenge. The situation has left many with false
assumptions, technology myths and, worst of all, a sense that virtualization
can cost more than it's worth.
all, the goal for most IT shops has been to do more with less, not less with
more, and virtualization platforms have come to represent increased management
needs, as well as higher operational overhead. Even so, the adoption of
virtualization solutions grows, as does the dissatisfaction with how much
savings can be delivered.
truth is that this is not a technological problem, but a management problem. Luckily,
that problem can be solved with technology, specifically virtualization
management technology. However, before diving into that that aspect of virtual
environments, IT professionals need to learn what the facts and myths of virtualization
are before taking a deep dive.
of the first things an IT manager should learn is that deploying a
virtualization solution is never a quick fix for other problems.
Marshall, director of global retail support for The Est??Â«e Lauder Companies, has
seen firsthand that deploying virtualization solutions is not without its
can present as many challenges as it solves," said Marshall. "Management becomes
more complex, thanks to hypervisor issues, platform changes and all of the
associated components needed to build a virtualization platform. It takes a
holistic approach, where virtual machines are monitored, managed and maintained
to truly benefit from everything virtualization has to offer."
