In IT terms, virtualization is cool. The rewards include cost savings,
agility, and flexibility. Enterprises reap the benefits of virtualization
through a much more efficient use of IT personnel and resources, faster
delivery time of applications, higher availability/service levels, and
additional capabilities such as high availability and disaster recovery. No
wonder data centers worldwide are being transformed by going virtual.
Now for the bad news: there are definitely serious drawbacks, especially
around compliance. If you think about virtualization, the hypervisor is now
the lowest part of the stack, existing below the operating system and
application. The virtual infrastructure is also a platform, which provides a
lot of management functionality, as well as capabilities that historically
used to require physical data center access (migrate virtual machine,

Remember the days when banking had to be done in the branch? Regardless of
whether you were making a deposit, withdrawal or just checking your balance,

teller both during business hours as well as after hours. Customers enjoyed
the ability to do their own banking without needing the "per... (more)

The company I work for, HyTrust, recently worked with Intel and VMware on a
very cool project.
Essentially, it was about demonstrating the ability to establish trust in the
cloud, and then enforce policy based on trust.
Trust is an important word in the world of security, and in cloud computing
it's an even bigger deal.
Cloud computing offers up the promise that an organizations will be able to
run any application from anywhere at any time. But in a multi-tenant
environment, a cloud application running in a virtual machine might be
Virtualization has brought us another step closer to the world of Star Trek.
Think back to episodes of The Next Generation where Geordi was able to
control the functions of the entire ship through a single touch-screen
interface. He was able to reconfigure electrical, mechanical and propulsion
systems without needing anyone else or additional authorization. The only
thing to prevent him from doing something risky or damaging was the computer
This picture is exciting in its similarities with virtualization. Here, the
hypervisor essentially becomes a datacenter in a... (more)

Like technology, everything in life tends to repeat, although in newer,
fresher and more useful applications. The fashion trend toward slim fit
clothes shifts to baggy, then back again; suits go from three to two button
and back to three; pastels and bright colors to earth tones as it shifts
anew. Car design is similar: Mercedes, for example, regularly goes back and
forth between rounded and square styles, and the re-birth of the Chevrolet
Camaro revisits the shape of one of my favorite classics - the '68 SS. Only
this time, newer, faster, slee... (more)
