Why the Switch to Cloud?
For a variety of reasons, cloud technologies are too compelling to ignore.
Dynamically scalable,
virtualized resources
provided as a service
Accessibility
Speed
Cost
 Maximize revenue
•
“Utility” billing (pay as you use)
 Reduce cost
•
“Unlimited” processing and storage
 Expedite time to market
•
Elasticity to scale up or down
•
On demand, self-service
•
Highly automated
 Focus resources
 Do more projects

Traditional VDI Reality
… but major BARRIERS exist
Start up
Huge up-front costs
Many moving parts
Complex to design & build
Operationally Intensive
Difficult to maintain
Is it strategic
Do you want to be building and
managing data centers

DISCLAIMER
•
TCO analysis is more contentious than politics so please understand this is one
TCO framework (there are many!). The numbers can be debated but feel free to
insert your own numbers into the framework
•
The numbers listed are based on list prices, industry averages, published analyst
numbers and customer feedback
•
This analysis was done with REAL customers
•
All of the numbers behind the analysis are not in the presentations but can be
found in our TCO whitepaper

Typical Oversights
•
Labor/Time
•
•
When comparing to physical PC’s most compare just the annual
cost of the physical desktop
Management Infrastructure required for VDI

Key Findings – Standard Windows 7 Desktop
•
Virtual desktops deliver savings upwards of 36% over desktop PC costs
•
Cloud desktops deliver further savings of 20+% over on-premises VDI
•
On-premises VDI delivers savings on labor but it is offset by the significant
extra infrastructure required
•
The performance requirements for VDI necessitate adoption of external
storage which adds substantial costs
