Virtualization Daily dissects the spin on a this article: "They seem to be wanting to make this controversial which is a little odd."

Server consolidation: Marcus Wynwood says all the cool kids are doing it:

Think about it, why would you want to look after a rack full of
servers, each with their own OS (that you need to maintain), each with
their own spaghetti cable and one big KVM
to switch between them when you really only need to look after one or
two servers? Instead of having lots of little servers, get your hands
on a fast machine with lots of RAM and a big hard drive, and start consolidating your servers with virtualisation.

Todd Biske via Joe McKendrick via Ipedo’s Integration Insider:

With SOA and Web services, "it’s entirely possibly to have dramatic
changes in load from when the Web Service is first deployed. As a new
consumer comes on board, the load on the service can increase by tens
of thousands of requests per day or more very easily. Furthermore, the
usage patterns may be vary widely. One consumer may use the service
every day, another consumer may use it once a month, but hammer it that
day. All this poses a challenge for the operational staff to ensure the
right amount of resources are available at the right time. The ease of
virtualization can allow this to happen."

Transforming Hyperic – What Developers Gain from Virtualizaton

While its true that most virtualization packages these days come with
management utilities, most of these are really bent around lifecycle
management – which includes provisioning, appliance construction,
backup, P2V conversion and monitoring of the hypervisor itself. What’s
ignored is the systems management inside the little black boxes that
get provisioned. These systems have unique applications and services
that are consuming resources. While the hypervisor does a good job in
general of providing CPU and disk resources based on your rules, it
does not facilitate really understanding the performance of those
applications and services operating in the made-up reality of a
virtualized host. The management problem is compounded by the ease of
which new virtualized systems can be rolled out along with the
flexibility of virtual hardware. Not only does this management get
harder, it changes more often.
