A couple of weeks ago Gartner released their “Top 10 Strategic Technologies
for 2009.” Each technology is defined as, “one with the potential for
significant impact on the enterprise in the next three years.” The
technologies listed have been available for quite some time – many of which
were present on last year’s list – but one that continues to move up in
rank is virtualization.
Considering the state of the economy, we anticipate this to be an area that
will continue to flourish over the next 12-24 months as virtualization
technology becomes feasible for businesses of all sizes. We’ve discussed
the economical (and environmental) benefits of virtualization in recent posts
found here and here.
So what do you think? Do you agree that virtualization is the #1 strategic
technology for 2009?
Thanks again to those who joined us for last week’s webinar, "Windows

We had a lot of good questions from our attendees during the Q&A portion of
the webinar, which are summarized below.
Q: How do you determine when to use an HA solution vs. a DR solution?
When it comes to availability vs. recovery, the most important question to
ask is what are your recovery time objectives (RTO)? What is the amount of
time your application c... (more)
Following the XenServer HA announcement, we’ve been approached with
questions like “How exactly does XenServer HA work?” and “How does
XenServer HA and everRun VM work together.” Rather than respond ourselves
we thought it would be best to point to a few fellow bloggers who have
already answered these questions.
First, here’s a good post written by Anil Madhavapeddy at Citrix discussing
how the overall architecture of XenServer HA works. Second, Scott Lowe has
put together a great summary of why Citrix and Marathon worked together to
develop XenServer HA.

Analyst firm The 451 Group has just released some very interesting findings
about virtualization and availability in a recent report by Chief Analyst
John Abbott. Some of the key take-aways include:
• Virtual infrastructure can form the basis of fully automated availability
processes. Availability becomes a default property of the virtual machine.
• ‘Dial up’ levels of availability can be implemented, depending on the
requirements of specific applications or departments.
• If a system restore is required after a disaster, it’s usually much
easier and much quicker to restore a virt... (more)
There are at least three straightforward steps that best practices companies
are implementing to achieve aggressive costs savings with their server
virtualization initiatives. I'll be reviewing these three steps in more
detail, along with customer use cases, in a webinar on August 19th, "How to
Get at least 2x Greater Cost Savings from Server Virtualization." To register
