5. Trends and Analysts for the future of Desktop
• The way businesses design, build, and deploy
desktops has been relatively unchanged for years.
• A process plagued with:
• productivity loss
• high security risks
• constant asset turnover
• and with an enormous price tag.
• Desktop virtualization is poised to make
significant strides to:
• improve this situation
• ultimately transform how IT manages
desktops
• transform how end-users consume
applications, choose endpoint devices, and
increase their productivity.

6. Trends and Analysts for the future of Desktop
• Gartner expects the
preferred client for
HVD deployment to
be refurbished desk-
based PCs and
gradually Thin Clients
will replace PCs
• “Hosted Virtual
Desktops (HVDs) have
great potential”

7. Challenges with Desktop Virtualization today
Challenges Performance and Scalability
implementing
Enterprise class User Experience: Can I guarantee same QoS for each and every user.
Virtual Desktop Poor performance in terms of bad user experience is a major issue
Solutions
Implementing few desktops is easy but can I do it for my enterprise
Capacity of underlying infrastructure in a datacenter
Is my server/network/storage ready?
Can we guarantee the SLA in a cost effective manner?
Data Center security: How can I bring desktops and keep other apps
secure
Manageability
Paradigm shift: Managing desktops in VMs vs Managing physical
desktops
Will the old ways of server manageability help in the future where
thousands of desktops are hosted out of the DC?

8. Changing the game in Desktop Virtualization
• Two market leaders joining forces
• Complimentary vision for desktop virtualization
evolution
• Fully validated and tested joint solution
