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.

Q&A: Windows Server High Availability

Thanks again to those who joined us for last week’s webinar, "Windows Server 2008 High Availability: Technology Comparison." The on-demand recording of last week's webinar is now available to watch at your convenience (here). 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)
