Client Computing Business Drivers: IT issues
• Desktop and application support &
management has plagued IT since corporate
adoption of PCs
• Desktop operating costs are high
• Rate of change - Mergers and
acquisitions/New employees/former
employees/contractors
• Security issues -- risk of information theft
• Work from home /mobile changed the game

• Virtualization across the infrastructure – Server virtualization => storage, networking, desktops
and apps – Purpose-built virtualization and turnkey private cloud
infrastructure – Economics & agility driving optimization & private
cloud
• Desktop & app virtualization
– Early desktop virtualization barriers being overcome: • VDI more reasonable CapEx with improved storage options • Technical improvements overcoming barriers
– VDI – Part of the solution not THE solution

• Consumerization of IT
– Cool devices, user preferences, instant on, access, response, real time info
– IT underestimated # of workers using consumer devices for work by 50%
– 67% of employees under 30 feel they have better technology at home than at work (Forrester)
– Born digital vs. taught digital
– Shift from desktop with apps to apps on desktops, laptops, tablets, phones & kiosks
• Unmet expectations=circumvention

• Organizations will virtualize exponentially more PCs than servers
• Storage -Disk I/O – Time congestion and synchronized behaviors require efficient I/O and storage systems (boot & AV Storms). Tiered storage, dedupe, SSD, caching
• Memory – as much as possible
• Networking – major shift/ increase in traffic, need to consider increasing LAN and WAN connection speeds, WAN optimization

• Boot Storms 30 -120 minutes • Initial OS and app load from disk • Patching, AV scans, EOD logoff • Profile/measure user resource usage with real
workloads • I/O Blender • Vendors like Lakeside Software, Liquidware Labs,
Flexera … collect data from users’ desktops to assess environment and need
• Tools like esxtop or Perfmon and from storage vendors to measure IOPS
• New SSD appliances help get below $200 per virtual desktop – with performance & capacity

• Which apps need to be delivered to which end users?
• Which users need app access versus full desktops?
• Which desktop OSs needs to be deployed?
• Will remote (WAN) or mobile users be involved?
• What level of performance is required?
• Will support be needed for offline/disconnected users?
• What type of graphics capability do various users require?
• What level of security is needed?
• How will the overall system and individual VMs be managed?
• How much control will the end user have over the virtual environment?
• How will VMs be backed up? How will VM images be updated?
• What are the requirements for business continuity/disaster recovery?

• Benefits of TC computing model – Minimal-to-no SW updates at
desktop devices
– Reduced support of users
– Extends lifespan of desktop devices
• For thin/zero client devices – Less vulnerable (smaller attack
surface)
– Green - Reduced power/cooling

DaaS - Cloud-hosted desktops
• Virtual desktops and apps from the cloud to any device with an Internet connection
• DaaS gaining traction vs other public cloud usage due to benefits of VDI without the complexities
• No SPLA for Win 7 or 8 VDI – most running published Windows Server desktop

• Understand your use cases before selecting solutions – flexibility to meet your use cases – (VDI, hosted apps, client virtualization, app streaming, BYO/mobile)
• Design user experience for your use cases – from zero client to advanced graphics
• Design for IT Efficiency – Storage – image mgmt, thin provisioning, dedupe, storage
optimization for VDI – Consolidation/density ratios in your environment – Bandwidth – LAN, WAN, networking impact – Consider integrated solutions
• Consider integration with app virtualization & app stores • Support for tablets/mobile – integration with BYO policies • Profile mgmt/personalization/ user virtualization • Administrative capabilities – ease, robustness
Client Virtualization Success factors

• Examine ALL your use case requirements
• Consider all access devices – PCs, thin/zero clients, tablets, mobile
• Consider desktop management and BYOD under a unified strategy
• Build cross-functional team (server, desktop, storage, net, security)
• Consider storage , networking & compute as key parts of decision
• Evaluate both user experience and IT infrastructure (storage, network and compute) impacts
• Don’t just treat desktops like servers
• Consider licensing implications – compliance & optimization
• Include both CapEx and OpEx in any ROI/TCO analysis
• Consider but don’t limit to your installed virtual. vendors
• Don’t be afraid of mix and match solutions
• One size does NOT fit all
