How many of you have management responsibilities over Desktop Assets? When you think of Desktop assets, what steps come to mind? Most of you know the drill extremely well by now, right? You start by procuring the Desktop systems, likely via your corporate IT procurement systems with CDW, Dell, etc. The Procurement process may take days or even weeks from the time of order to the time of physical delivery. Next you must image the system with the standard Operating Systems and even Standard Applications. Follow that up with securing the system via any latebreaking patches as well as any Antivirus tools and upgrades. Then and only then are you ready to deploy the system out to your user or users, wherever they happen to be – physical corporate office, branch office, home office, etc. [Hand up asking for show of hands] “ How many people only have users who are collocated in ONE location?” “ How many people have users who span MULTIPLE locations?” Now, we had a good number of folks (reference and point to a couple) who indicated they have users who span multiple locations. Well, now you get to monitor and support those same users. They could be living out in a remote geographical location and you and your staff gets to support them all the same! You get to maintain those same desktop and PC systems, and to stream security patches and both OS and app upgrades out to those users. Those systems have to be backed up , wherever they happen to be, so at the very least, the critical USER data is backed up on corporate servers and storage. Last but not least, at some point, likely after the Service and Maintenance Contracts have expired, you will have to retire those physical systems. Only to procure new desktop systems – every 3 years or so - and start the cycle all over again. These processes are so well known, we’ve all lived them. But let’s also look objectively at some of the pitfalls of this traditional Desktop Deployment approach: One – they are SLOW to deploy, taking days or even weeks to activate. Two – they are DIFFICULT TO SECURE Three – they are extremely costly to maintain, running $4-9K per desktop annually per Gartner. I’d like to share a personal story of mine. About two years ago, I was starting a Marketing Consulting contract at a yet-to-be named leading Internet Portal company (It’s not Google and it’s not Microsoft/MSN) Upon starting this 3-month contract, I was assigned a corporate laptop for my work. The system had to be procured by IT. After we expedited the order, IT received the laptop from the vendor after 10 days. The imaging, securing and deployment took an additional 4 days. Then when I received my accelerated system, the very first time I powered up my system, I got the fabled “Blue Screen of Death.” Not a good way to start a 3 month contract gig, 2 weeks into my new job!
At this point, you may be asking yourself: “How can I Break out of the traditional Desktop Deployment” model? A key first step is to think of a Desktop system as a construct of components including: The Physical Device (Laptop, Desktop HW, etc.) The Operating System The Applications (which nominally get installed on top of the OS)
Now we have spoken to a LOT of customers. We understand that many of the customers who have adopted Gen 1 Virtual Desktops struggle with a few challenges: The most frequently heard challenge has to do with Virtual Desktop Sprawl Despite the fact that these virtual desktops are centralized inside the data center, fundamentally there are just still too many unique desktop images to manage and maintain. Furthermore, Desktop Workloads on individual Servers is extremely hard to predict As a result, both user and application behavior are unpredictable. Last but not least, when individual user virtual desktops are stored discreetly, the Storage Costs Scale Linearly and Become Prohibitive. Basic math says, that: (20 GB/user) X (50 users) = 1 Terabyte of Storage immediately!
Furthermore, separating Apps minimizes Desktop Image Sprawl. Effectively, many users can share ONE common base image. As a result, you need to only store, update, roll back, and refresh ONE desktop image. The net:net is that you can reduce storage requirements by up to 90%!
What if you could take it a step further and to deliver Desktops NOT as distinct IT assets to be individually providually procured, imaged, deployed, and managed? What if, we were to allow IT Organizations to Deliver Desktops as a Service, to be allocated and assembled real time, whereby all the core Management and Maintenance were centrally managed?
Taking advantage of this new vision of the Desktop, Citrix XenDesktop delivers desktops as the core sum of the three components: Desktop OS image Standard Applications Set User Profiles to store individual user settings (examples including Internet Explorer Favorites, MS Office Templates, Photoshop UI look and feel, etc.) It then dynamically assembles and delivers virtual desktops (as the sum of the 3 above components) real time to the end users over any network, and to any device. Inside the data center, however, there is one single instance of the Desktop OS image (Gold Master), Application set image, and the User Profile image. As a result, there is ONE single instance of the Desktop OS, the Apps, and the User Profiles to be store and manage centrally.
The Citrix vision, as we alluded to little earlier, is to separate the apps from the desktops. By doing so, we want to help customers like yourselves reduce costs by making the tasks of application management and desktop management EASIER.
The vision can be summed up as what we at Citrix like to call “ Power of One” ONE image of apps and desktops ONE password & identity ONE instance of data ONE consistent user experience anywhere, anytime.
At this point, you may be asking yourselves: “ Well, this is all great that Citrix lets ME separately store and manage a single instance of the OS, the Apps, and the User Settings. SO WHAT?” Citrix’s XenDesktop enables very tangible benefits including: A very compelling business case, measurable in significant TCO savings, a strong Return on Investment and compelling Net Present Value for your Desktop Implementation Strategy. More importantly, XenDesktop also provides some measurable indirect business benefits as well, such as Security, User Productivity, and Lower Desktop Refresh Costs.
Let’s take a detailed look at the TCO differences between a traditional Desktop versus a Server-Style Desktop. In particular, the Total Cost of Ownership can be simplistically broken down into 5 categories: HW + SW Operations Administration End-User IT Costs Downtime You can see very quickly that the dials which most directly and drastically reduce Desktop TCO are: HW+SW Costs these include the Capital Expenditure associated with the acquisition costs of the client/server HW and related OS and applications End-User IT These include the imaging, Downtime
The Net Net from a Cost Standpoint, is that a Server-style Desktop enables significant Cost Savings compared with a Traditional Desktop. These Cost Savings include: 29% reduction in IT Operational Costs 40% reduction in HW & SW Costs A whopping 88% reduction in Worker Downtime Costs And a huge 78% in overall IT Staff Productivity.
Let’s take a look at a sample customer implementation and the benefits realized with a Hosted VM model over Traditional PC’s This compares the actual costs associating with two comparably sized desktop implementations. In the first “Traditional PCs” example, the implementation involved ~1100 physical desktops. Accounting for Infrastructure Costs, Administration, Apps Admin, Power & Cooling, etc., the Total Cost per Device per Year is approximately $7000. By comparison, the “Hosted Virtual Machine” example shows the same categories, but with the Total Cost per Device per Year is ~$3800. That’s over 45% savings!
