Transcription

1 Session 6: Desktop Deployment Mark Aslett Consultant Adam Shepherd Consultant MCS Talks Infrastructure Architecture

2 Agenda Introduction Assessing the Infrastructure Creating an Image Maintaining the Image Deployment Strategies Common Scenarios Virtualization

3 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

4 Introduction - Infrastructure Optimisation Uncoordinated, manual infrastructure; knowledge not captured Managed IT infrastructure with limited automation and knowledge capture Managed and consolidated IT infrastructure with extensive automation; knowledge captured and reused Identity and Access Management Desktop, Device, and Server Management Desktop Management Security and Networking Virtualization IT and Security Process Fully automated management; dynamic resource usage; businesslinked service level agreements; knowledge capture and use automated Cost Center Server Management Data More Protection Efficient and Business Recovery Cost Center Enabler Mobile Device Management Strategic Asset Basic Standardized Rationalized Dynamic

5 Common Deployment Challenges Typical problems faced during an OS rollout in a large organisation Wide mix of hardware Environment spread across multiple locations Variety of network and infrastructure availability Numerous applications to support Inconsistent policy and process across the business Multiple support groups working independently Resistance to change

6 MCS Talks Infrastructure Architecture ASSESSING THE INFRASTRUCTURE

7 What do I need to know? Are my applications compatible Is my infrastructure ready? What does my environment look like? What hardware do I have on the estate? What is our business strategy for the next 5 years?

8 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

9 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

10 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

11 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.

12 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

13 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 3 rd Party Tools can help reduce the cost and complexity

14 Application Compatibility Remediation Common approaches Approach ISV / Upgrade Create a SHIM (ACT or 3 rd party) Different software Terminal Services Virtualization (later)

15 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

16 MCS Talks Infrastructure Architecture CREATING AN IMAGE

17 Building an image common questions What languages are required for my environment What applications should I include in my image? What drivers do I need? Will I include them all or deploy later? What processes should I use to create an image? How many images will I require?

18 MCS Talks Infrastructure Architecture MAINTAINING THE IMAGE

19 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 often should I update my image? How do I keep my image up to date? What s should my change control process look like?

20 MCS Talks Infrastructure Architecture DEPLOYMENT STRATEGY

21 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

22 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

23 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?

27 Considerations for deploying the image Call Centre Campus Data Centre York Office Newcastle Office

28 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

29 MCS Talks Infrastructure Architecture VIRTUALIZATION

30 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
