Introduction - Deployment
Focus on Microsoft Windows Desktop Deployments
Looking at strategy not technical details
Some assumptions:
Basic infrastructure in place, e.g. Active Directory
Basic infrastructure in place for deployment, at least able to deploy patches, anti-virus definitions

ASSESSING THE
INFRASTRUCTURE
MCS Talks Infrastructure Architecture
![Page 7: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/7.jpg)
What do I need to know?
Are my applications
compatible
Is my infrastructure
ready?
What hardware do I
have on the estate?
What is our
business strategy
for the next 5
years?
What does my
environment look
like?
![Page 8: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/8.jpg)
Knowing Your Environment
Physical topology
Network topology
Hardware / software inventories
Users
What are the key challenges facing my users
Can users be categorised in terms of what they require to perform their role
![Page 9: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/9.jpg)
Business drivers and technology strategy
Is there a business case for the deployment project?
Business and technology strategies:
Enhanced Mobility
Changes to physical topology
Consolidation
New usage models (Thin Client / VDI)
File services
32-bit vs 64-bit
Security and BitLocker
Standard User Desktop
![Page 10: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/10.jpg)
Is the Infrastructure Ready?
Infrastructure to support deployment:
Is existing infrastructure fit for purpose
Are changes required to support the features of the new operating system
How should changes to infrastructure be handled?
Separate vs. composite project
Before vs. during deployment
Other infrastructure projects planned or in progress
![Page 11: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/11.jpg)
Hardware
Understand the Hardware estate
Hardware in the estate today and for deployment
Hardware refresh cycles
Use existing tools or Windows Vista Hardware Assessment Tool
Device Drivers
Can have a big impact on performance and reliability, get the latest.
Peripherals
Don’t over look them, some will be business critical.
![Page 12: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/12.jpg)
Understanding your application estate
Available resources?
Software Inventory and Metering
Definitive software library
Source files and UAT scripts
Time for a change?
Consider application rationalisation
Consider which applications are productively used
Advantages to upgrading to a later version or different LOB application
![Page 13: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/13.jpg)
Application Compatibility Testing
One of the biggest deployment blockers
Plan appropriately
Can be biggest undertaking
Consider how many business critical applications are old and out of support
ACT and 3rd Party Tools can help reduce the cost and complexity
![Page 14: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/14.jpg)
Application Compatibility Remediation
Common approaches
Approach ISV / Upgrade
Create a SHIM (ACT or 3rd party)
Different software
Terminal Services
Virtualization (later)
![Page 15: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/15.jpg)
Microsoft Office Migration
OS Migration is frequently coupled with a Microsoft Office migration
Things to think about:
Discovering what Microsoft Office files exist
Understanding what Microsoft Office files will be compatible with the later version of Microsoft Office
![Page 16: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/16.jpg)
CREATING AN IMAGE
MCS Talks Infrastructure Architecture
![Page 17: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/17.jpg)
Building an image – common questions
What languages are
required for my
environment
What applications
should I include in
my image?
What processes
should I use to
create an image?How many images
will I require?
What drivers do I
need? Will I include
them all or deploy
later?
![Page 18: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/18.jpg)
MAINTAINING THE IMAGE
MCS Talks Infrastructure Architecture
![Page 19: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/19.jpg)
Maintaining an image – things to consider
How do I handle
version controlling?
How do I keep all my
systems at the same
patch level?
How do I keep my
image up to date?What’s should my
change control
process look like?
How often should I
update my image?
![Page 20: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/20.jpg)

MCS Talks Infrastructure Architecture
![Page 21: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/21.jpg)
Deployment Scenarios
Lite or Zero Touch approaches
Which methodologies to use:
Refresh
Replace
Bare Metal, OEM (birthing information)
Media based install
Which technology to use:
System Center Configuration Manager
Microsoft Deployment Toolkit
Windows Deployment Services
![Page 22: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/22.jpg)
Managing Deployments
Deployment approach:
Deploy realistic numbers
Avoid allowing deployments to run over a long period of time
Be realistic about how long a deployment project will take
Pilot, ramp up slowly and fix problems up front
Allow time to train users, helpdesk first
![Page 23: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/23.jpg)
Migrating Users
What needs to be migrated?
Data, settings or both?
How should user state be migrated?
Manual vs. automated?
Where will data be stored?
When will migration take place?
Co-existence with down-level operating systems?

Considerations for Application
Deployment
Application provisioning:
Applications in the image
Role based vs. user based
Based on previous machine
Application source files
Consider where they’re required
How much storage will they need
How long do you have to replicate updates
![Page 29: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/29.jpg)
VIRTUALIZATION
MCS Talks Infrastructure Architecture
![Page 30: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/30.jpg)
Virtualization – deployment considerations
Applications Virtualization (formerly SoftGrid)
Consider for change to app strategy
Not the silver bullet for application to OS compatibility issues
Presentation Virtualization (Terminal Server)
Good for hosting intensive or data heavy applications
Enterprise Desktop Virtualization (formerly Kidaro)
Not available yet, but essentially puts a VPC on the users desktop
![Page 31: Session 6: Desktop Deploymentdownload.microsoft.com/documents/uk/technet/postevent/15... · 2018-12-05 · Session 6: Desktop Deployment Mark Aslett –Consultant Adam Shepherd –Consultant](https://reader033.vdocuments.us/reader033/viewer/2022052720/5f082f9e7e708231d420c447/html5/thumbnails/31.jpg)
