VDI Tales from the Crypt - the Terrible, Horrible, No Good, Very Bad Downtime Day
In talking with Login VSI customers daily, I often probe to understand what issues the organization is having with its virtualized desktop environment. I offer Login VSI and Login PI as solutions, because end user experience, end user performance and scalability are often central to customers' concerns. I ask, “have you ever had downtime or end user complaints due to performance lapses?” The responses vary depending on the mood of the engineer or IT decision maker, but most people cringe and then enthusiastically vent about that “very bad day.”
VDI environments are the cherished babies of the IT departments who are tasked with managing and nurturing these complex, dynamic creatures. Checking your helpdesk ticket folder after a major upgrade or change can give even the most Zen engineers anxiety on patch Tuesday.
911 Phone Calls
Regularly we receive 911 phone calls in the form of quote requests from an enterprise who either made a major change to their gold image or recently deployed a Centralized Desktop Environment and chaos ensued. Ironically enough, the majority of these 911 phone calls come from hospitals. One story in particular sticks out and gives me goose bumps upon recollecting. A major hospital in the country was in the process of upgrading their EMR software to the latest version.
A few members of the hospital’s IT staff were apprehensive about deploying the upgrade due to concerns about additional resource requirements for their particular environment. The EMR software provider convinced the staff that if they made a few simple changes that It would not carry a big impact. The IT staff made the changes recommended by the vendor, but by 10:00 AM the day of deployment they realized they had a problem and had drastically underestimated the additional hardware required. The performance became so bad that by peak hours login times skyrocketed to almost 30 minutes and they had to medevac (use a helicopter to transport) IC patients to a different hospital. This demonstrates the surprises that can surface when general guidance doesn’t apply to a customized production deployment.
Hopefully none of you have a story as grim (and pricey) as this one! We all deserve to vent from time to time. In the spirit of Halloween we invite you all to share your VDI horror story on Twitter with the hashtag #VDIGoosebumps!
Whether you use our products today or not, please think about load-testing your centralized desktop environment before you deploy. Login VSI can help you stress test environments and deploy changes with confidence ensuring happy users.
Because… at the end of the day happy users = happy IT :-) and at Login VSI we always prefer the treat over the trick!
