Virtual Desktop Infrastructure (VDI) David G. Young Jr. Desktop Systems Engineer
Desktop Infrastructure Challenges Distributed workforce Mobile & remote workers Outsourcing & off-shoring Contract Workers Limited control of PCs Patch compliance Security Regulatory compliance Management complexity Deployment Support Security Focus on PC hardware Many makes & models Refresh cycles Reducing Cost CAPX/OPX
Typical Corporate Desktops The corporate desktop PC model has changed little in nearly 2 decades.
Typical Corporate Desktops In most environments, the components are linked together in ways that are difficult to support and maintain.
Problems Can Start At Any Layer A problem at one layer often causes a chain reaction that can destroy the whole stack.
Local Failures Can Mean Data Loss This makes recovery difficult and threatens any locally stored user data and settings. Most organizations just replace or re- image the whole PC.
There has to be a better way… Could a Virtual Desktop be the answer?
VDI Enables Hardware Independence Desktop OS Virtualization breaks the link between the Operating System and any specific hardware.
Virtual Desktops Leverage File Servers Effectively VDI proximity to the data center also enables data isolation through file shares and profile management.
File Shares and User Profiles This allows users to access any VM and always get their data and their profile.
Virtual Machines with Everything We could install all of the applications that everyone needs in all of the machines.
And the more applications you install, the less stable things tend to get. Overall System Instability
What’s new with VMware View 3 VMware View 3 View Composer Offline Desktop (experimental) Unified Access Virtual Printing ThinApp Reduce storage costs Reduce app conflicts Increase density Reduce support costs Increase laptop security and recovery
VMware VDI Solution Overview - Current Extended Win32 client Browser on Linux, Mac Direct from thin clients RDP/ HTTPS RDP Windows XP Windows Vista Optional integration with RSA SecurID Automated provisioning and desktop management DMZ deployment option Integrated solution including: VMware VI3 Enterprise Virtual Center Virtual Desktop Manager
vClone Direct Storage Cost Savings Dramatically (90%+) reduce the amount of storage consumed Increase overall performance due to better storage controller / cache utilization. 10 GB OS 25 MB Clone Ratio% Savings 1:5085%+ 1:10090%+ 1:100095%+
Create Conflict Free Applications Symptoms: Application Conflicts Complex Compatibility Test Matrices Diminished Time to Deployment Loss of User Productivity Solution: VMware ThinApp Agentless application virtualization decouples applications and data from the OS Problem: Tightly coupled relationships between OS, Applications and Data
How ThinApp Works: VMware ThinApp links the application, Virtual Operating System (VOS), file system and registry into a single EXE/MSI file Application Encapsulation & Isolation Intercepts file and system calls Process Loading- start exe from VOS, Launch from host OS (Virtual/Physical). DLL Loading. loads DLL dependencies the EXE/DLL/OCX files from archive Thread & Process Management. VOS tracks all processes and threads inside virtual registry (COM & Utility)
Simplify Desktop Delivery & Costs with VDI & ThinApp Reduce Storage Reuse templates Install VM without apps Simplify Software Delivery (no agents/infrastructure) Multiple versions of same app installed on VDI image Many ways to deliver shortcut Plugs into existing App Mgmt tools w/o infrastructure Streamline Patch Updates Modify 1 app for whole environment In place upgrades
Unified Access Support other platforms accessible by RDP Terminal Server Blade PCs Physical PCs Increase in device support Broader USB Smart Card and CAC Universal Printer Blade PCs Terminal Servers Physical PCs
Virtual Printing Driver Free Printing: No Installation and Maintenance of printer drivers on Virtual Desktops All necessary printers automatically available Minimize network utilization up to 98% with advanced print stream compression High quality printing even over WAN connections Use of client printer driver rather than complicated server installations View Client RDP View Client RDP
Offline Desktop Offline VDI End-users can check-in and check-out their virtual desktops Administrators can extend security policies to the local computer Near approximate of the full local experience Offline VDI
Linux / Partner Clients SVI VDM Clients AD VC Offline Unified Access Let’s bring it all together…
Don’t Make Big Virtual Machines So instead of installing everything into huge cumbersome VM’s.
Create the Smallest VM Possible We install nothing but the OS from a single template.
Deliver Apps and Data on Demand And deliver applications on demand from a file server.
Deliver Apps and Data on Demand Based on what the user actually needs or has permission to use.
A Single Location for Applications Creating a software repository.
No Distribution Needed Eliminating the need for software distribution.
User Space System And we store the sandbox in the profile where it can follow the user. Thinapp Blocks System Changes
Deploying Updates… User data disks are “connected” to the new master at next login or user prompt. IE7IE6
Creating vClones Create a baseline Windows virtual machine on your Virtual Infrastructure. V1
Building Desktops with vClones This replica will then create a set of small linked clones and join them to the domain. V1
Building Desktops with vClones Profiles are stored as user personality disks, created on first logon if necessary. VMV1
Building Desktops with vClones User data is stored on virtualized file servers. V1
Building Desktops with vClones Thinapps are launched from network shares V1
Building Desktops with vClones The user’s PC is the resulting combination. V1
Building Desktops with vClones V2 Update the baseline Windows VM with a patch. V1
Building Desktops with vClones V2 V1 Publish the new SVI source VM. V2
Building Desktops with vClones V2 As users log out, the clones are deleted… V2 X X X X X X
Building Desktops with vClones V2 …and attached to the new master replica. V2
