2 Introduction What is Virtual Desktop? Why the change? Approach What does this enable? Virtual Desktop Architecture End Node devices Thin client Repurposing Application Virtualization Lessons Learned The dirty little secrets the vendors wont tell you Live Demo

3 A virtual desktop is a copy of Windows running on a server in the data center instead of on a PC Application Virtualization – applications run in a separate bubble and do not directly interact with the operating system Server Virtualization – multiple virtual servers run and share a single physical server

4 Reduce complexity of computing environment Security Simplify security patching Reduce virus scanning Increased data security Eliminate software distribution Reduce application variability Reduce hardware cost

5 Push the boundaries Take more risk Limit options to drive penetration and speed Faster with more risk Wont have all the answers – exploratory in nature

6 New acquisitions can quickly be given access to our corporate applications No need to buy specific Air Products PCs, make use of existing PC and browser Install dumb terminal from local supplier JVs & Outsource partners can get access to our applications, and we can limit what they can see & do. Improves security and helps prevent loss of our corporate data This is foundational to other offerings

7 Broker Hypervisor Provisioning App Virt. ICA

8 (1) Secure USB compartment (2) Power button (3) Flash activity LED (4) Line-in (microphone) connector (5) Line-out (headphone or speaker) audio connector (6) Universal serial bus (USB) connectors (2) (7) Power LED

9 Needed to leverage our existing assets 4 year purchased PC replacement cycle 65% laptop population Windows licensing is per device and we dont have Software Assurance allows user mobility without increasing license costs Potential options Ubuntu Linux hardware driver difficulties with laptops WinFLiP (Windows for Legacy PCs) – not made for mobile PCs Group Policy lockdown (Air Products choice) Takes a Windows PC and makes it a thin client Avoids a PC reload Provides a no touch approach User has no ability to access most items, make changes, or access hard disk or programs

10 VDI is accessed via the users desktop or laptop (repurposed PC) The physical PC is locked down with these exceptions: accessing the Internet (how users get to VDI) Saving printer and network info making minor adjustments to the display and mouse settings The user moves Outlook PST folders into their 2GB mailbox Migration User data is moved from your PC to the Virtual Server (5GB limit) The Outlook profile will NOT be migrated – users will recreate it Only certain settings will be migrated from the Windows Profile It will take 1-2 days to become adjusted to using the new virtual desktop so plan accordingly Applications accessed by base image, Citrix hosting, virtualized streamed applications, or the web Only applications necessary for business will be made available

11 First focus must be to limit the number of applications to minimize $$$$ The focus is on business applications No personal apps (non-business applications) Standardization and single versions are a must Transparent apps have been interesting Transparent apps are allowed but are not IT supported To make them available in VDI, we must sequence them Can drive cost if encounter too many of these

12 Listed in order of preference Web application minimal/no footprint Virtualized application Leaves no residual code on the desktop Requires effort to sequence the application AppV, ThinApp, or XenApp Only 80 – 90% of apps can be virtualized Hosted application (Citrix or Windows Terminal) May not be an option if application interoperability is necessary Many apps interoperate with MS Office Install in VDI O/S base image Include anything that frequently operates with other apps (MS Office, PDF reader, etc) Any app included will require a license for each VDI user Any changes require an update to the base image

13 MS App-V Application Limitations Over 4 GB in size when sequenced Start services at boot time Require device drivers – ex. Print drivers Part of the OS – ex. PowerShell COM+ and COM DLL surrogate virtualization 64-bit applications – coming in App-V 4.6 release

14 Heavy data analysis to define your market Highly mobile users, users with variable bandwidth or high latency, and users with one-off apps are not good candidates How do you determine who those users are? Dont underestimate migration effort Consider Windows profiles, Outlook profiles, PST files, file shares, printing, etc. carry over as little as possible Remember network bandwidth impacts Each VDI implementation is unique Cost versus control Starting point Admin rights, data location, PST files, bandwidth availability, persistence, application space, etc. Understand business continuity plans There is no offline use in VDI Verify MS Office apps are not part of their plans

15 Software licensing requires a PhD Software vendors have not thought through licensing the virtual world Several unexpected license costs – e.g. VECD, AV scan Vendors & complexity No vendor owns the whole game Immature monitoring and performance tools Stability & performance requires $$$$ Browser-based apps are not without issues Shared folders & ActiveX Controls Cookies Thin clients take MORE bandwidth Bandwidth and wireless variability are not VDIs friend
