2. About Us 1 of 13 regional authorities 120,000 people served
18 facilities
5,000 staff
2,700 devices
14 IT staff members

3. Current Setup (simplified)
Provincial Citrix Farm
Local Citrix Farm
User

4. Challenges
Centralized hosting of applications causing longer log in times (sessions between two Citrix farms)
Multiple sign-in credentials
Sharing of user credentials
Required to log back in from one location to another
Challenges in default printer mappings; printers do not change based on location

5. Solution: Patient First Desktop Virtualization
Retrieve clinical information faster
Encourage greater use of EMR
Increase security with two-factor authentication, stop non-clinicians from accessing information – Use of Smart Card +Pin, eliminate the long user name and password
Introduce Single Sign On
Provide anywhere, anytime access to information from any device (“Follow Me Computing”)
Simplify desktop management
Reduce boot times, save energy with zero clients

6. Deployment Results - Then
530 Virtual Desktops (1000 users)
249 Persistent
281 Non-Persistent
92 Application Layers
1 Gold Windows OS layer
5 GB Disk Space per Desktop

7. Deployment Results - Now
845 Virtual Desktops (2000 users)
344 Persistent and 771 non-pers. (1115 current)
225 Persistent and 620 non-pers. (845 after opt.)
2 Gold Windows OS layers (1 after optimized)
Projected 1500 VDIs for users
Est. 1 VDI for every 2-3 users
25% to 33% persistent;
66% to 75% non-persistent
1 Persistent and 8 Non-Persistent Pools
152 total layers used in production
88 unoptimized; 64 optimized
After optimization complete will be 60 layers

8. Deployment Results - Now
VDI Specs
Before Optimization: 1CPU/2GB Mem
After Optimization: 2CPU/4GB Mem
Daily backup of Persistent Personalization
(2 day retention)
5GB user space
Weekly Unidesk Appliance and Layer backups
Simple 1 CP -> 1 ESX Host -> One Datastore relationship
16 ESX Hosts in a DRS cluster; 3 new ESX hosts to be added

9. Our Clinical Environment
AllScripts SCM – (Acute EMR)
WinCIS – (Admission, Discharge and Transfer System)
WinRECs – ( Transcription , CIHI stats system)
RIS \PACs – (Philips \ Cerner – Diagnostic Imaging system)
Accuro – (Clinician EMR)
Microsoft Dynamics – (Financial Application)
Microsoft Office 2007
Various Labeler and Scanners (Handheld and Desktop)
Many custom one-off applications

10. Deployment Times Layer Creation + Testing: VDI Creation
Simple/Average layer = days
Complex layer = 1-2 weeks (mostly trial and error/testing)
VDI Creation
1 VDI can take 15-30min depending on complexity of the layers
Multiple VDIs can be created at same time
Ex: Our environment can create over 50 at a time

11. IT Staff Resources
2 Dedicated Technicians to research plan and migrate locations from workstations to WYSE devices + VDI.
2-4 Help Desk technicians (not dedicated to VDI)
3 Server Team Analysts (not dedicated to VDI)
Troubleshooting (Average) Times
Simple Issues: 15 minutes
Medium Issues: 30 minutes
Complex issues: ranges from 1 hr to 1 week or more depending on complexity

12. Why Unidesk ?

13. For the IT department
Simplified the move from WinXP to Win7 and eventually to Win10
Centralized/easy method for testing, deploying and updating desktops/apps
Reliable Baseline for every update
Can easily wipe and restart updates. No mess like with uninstalls.
Less variation in how desktops are configured making troubleshooting easier
Break-fix for a desktop with Unidesk rollback done in less than 20 mins
Can easily clear any user persistent data to return to baseline
Simplified desktop management
One Image \ Single layer reduces the update time for patches \ updates

14. For the IT department Ease of use
Moving between application versions/OS updates
Adding/removing applications
Deploying changes to large groups of VDIs
Upgrading Unidesk software
Submitting logs
Reporting/Analysis tool
Very responsive and knowledgeable in both planning with Architects and troubleshooting with Support

15. For the CFO \ Finance department
Single image – less storage – reduction in storage cost
Increase productivity – reduction in end user “downtime” – User gets access to a new desktop or re-imaged desktop in less than 30 minutes compared to a week or so in the past
Reduction in PC vs. Zero Client cost – The cost reduction was so high that we were able to hire two new full time IT staff members

16. For the End User
Increase productivity - “Follow-me Desktop” allows reconnection from any device as well as bed side charting
Reduction in end user “downtime” – User gets access to a new desktop or re-built desktop in less than 30 minutes compared to a week or so in the past
Increase turn around for new application request.
Consistent access \ experience across multiple desktop platforms. ( IOS, Windows, Android) – Same Shortcuts, app settings (Unidesk Personalization)
Access to a full Virtual Desktop ( Unlike one or two virtual apps, the user gets access to the entire desktop, files, settings, apps, etc)

17. Why Imprivata? Determined to be the best fit based on Provincial RFP
Highly Available architecture
More user friendly than the Citrix SSO we used in the past
Customize credential learning for most applications/logins
Works with published application servers (ex: XenApp)

18. Why Appsense? Fits the “Follow Me” Desktop strategy.
Ability to save/transfer users settings between computers
Wide variety of tasks that can be performed at different stages
Computer startup, user login, application execution…
Set/Adjust a wide variety of settings
Execute programs or scripts
Set licenses, registry, GPO, map drives or other settings
Create/copy files and folders

19. Challenges we faced with VDI…..
Initial planning was not optimal
Layer creation and documentation was not optimal creating issues troubleshooting
Some Apps could not be virtualized due to software and/or licensing
Focused too much on persistent VDIs
Resistance to change from employees

20. What we have learned so far…
Planning is key
Keep things simple
Avoid unnecessary pre-requisite layers
Don’t join domain when creating layers unless necessary
Avoid connecting devices (ex: USB) unless necessary
Keep detailed documentation of layer creation/update steps
Consistency: Templates are your friend
Have proper test users for each application
If you make a mistake during layer creation/updates, start over. Don’t uninstall your mistakes.
