In my previous blog, I talked about how virtualization is picking up momentum in the healthcare industry and how this is resulting in simplified clinical workflows and providing nurses and physicians with fast access to the applications and information they need to support positive patient outcomes. In this blog, I would like to touch on one of the key areas where virtualization has made a significant impact – desktop virtualization.
Hospitals frequently use shared dictation terminals to host their clinical dictation applications. As doctors complete multiple patient rounds, they make their way to one of these dedicated workstations, plug their personal microphone into the workstation, and dictate their notes from their previous rounds. The delay between completing rounds and dictating patient data is inefficient, but more importantly, it creates the potential for errors. Access through shared and dedicated workstations also tethers the clinician to specific terminals that can only be used when the doctor is in the clinic. For example, there is no easy way to access clinical reference imaging applications when the doctor is away from the clinic and wants to quickly review images for a specific patient. Instead, the doctor must either call a peer at the hospital to review the images, or incur travel time to go to the hospital.
Finally, although the shared workstations distributed across the clinics and hospitals are centrally managed, the software operating on each workstation can quickly drift away from its original configuration as users install specific applications not hosted by the data center or use the workstation in other ways that compromise the original “golden image.” As a result, every workstation and application that a caregiver uses can behave differently. A hospital’s IT group can potentially spend most of its time chasing repetitive workstation issues and errors, as well as managing different instances of almost applications. IT administrators constantly face the challenge of unwanted installations, as well as the incompatibility between images from one shared workstation to the next. Upgrading desktops and applications can be a difficult task, requiring many hours of effort on each workstation.
Change. It’s part of how we work, live, and play. Change is inevitable and often feared rather than embraced. However, change could be a catalyst for innovation, a new way of doing things faster and more efficiently. It allows companies to capitalize on opportunities, creating strategic long-term value while also meeting immediate operational needs.
The market is changing and so is the IT landscape. By 2014, more than 70 million virtual desktops will be connected and 90% of organizations will allow work applications on personal devices (Gartner, 2010). Similarly, by 2015, 1.5 billion mobile devices will connect to the network (Gartner, 2011). These transitions add intense burden to the network, from manageability to security, availability, and scalability. IT leadership often turns to stopgap measures such as getting faster WAN links to handle increased traffic. But that doesn’t solve everything. Organizations that want to propel forward (i.e. be competitive) must change their focus – that is focus not only on bandwidth management, features, and bytes, but also on business agility – giving themselves room to grow. One pharmaceutical services company did that with Cisco Borderless Networks infrastructure. Read More »
At Cisco Live, I had the good fortune to sit down with Steve Kaplan of Presidio (@ROIdude), and Sreekanth Kannan of VMware, to discuss the current landscape of desktop virtualization as seen through the experiences of our customers, key enabling technologies we’re excited about, and some thoughts about what to expect looking forward. Watch the session
It is Cisco Live 2012, and the San Diego Convention Center is abuzz with excitement and activity, as customers throng to the World of Solutions, on this Monday afternoon, June 11. Having recently joined the Cisco VXI solutions marketing team, I am eager to check out all the VXI demos live on the show floor. Let’s pick up action with the Desktop Virtualization demo in the Cisco Unified Data Center (UDC) booth. Read More »
Today I invited Bhumik Patel , Alliance Engagement Architect at Citrix, to write about some aspects of the collaboration between Cisco and Citrix to provide the best workspace experience to our customers. Bhumik is responsible for delivering technical best practices and joint solutions on Citrix XenDesktop and Cisco VXI desktop virtualization solutions for customers and partners. He has been with Citrix since 2007 and is based out of Santa Clara; CA. Prior to this role, Bhumik was part of Citrix’s WW Consulting group leading consulting projects for several enterprise Citrix customers around the globe and has led initiatives for developing best practices while integrating Citrix and partner solutions.
“As a Citrix Architect implementing Desktop Virtualization solutions with Cisco VXI and Citrix XenDesktop in the field, I would like to share some of the successful business use cases that a joint solution addresses primarily from a Citrix viewpoint. Since Cisco VXI is a unique, end-to-end architectural solution integrating virtualized data center, virtualization-aware networks and virtualized collaborative workspaces for optimally delivering virtual desktops with XenDesktop, it is really built to drive multiple I.T initiatives for you at once, all leading towards a flexible, next-generation workspace. Let’s look at the VXI solution at a very high level and then a few practical use cases:
First and foremost benefit is with Cisco UCS providing an ideal platform for hosting Citrix XenDesktop delivering virtual desktops for organizations. With the extended memory technology providing great VM density, and the service profiles allowing customers to dynamically build and scale out their infrastructure hosting XenDesktop. UCS also provides a great end user experience even for some very large VM footprints due to the unified fabric supporting very high I/O bandwidth. The solution with UCS and XenDesktop is completely validated and tested for providing the required density numbers. I had the opportunity to contribute to the initial validations with Cisco and you can read more on it here. So the guess work is eliminated while implementing your VDI solution, which could be a huge benefit in itself.
