Thick, Thin, and PCoIP Zero Clients
>
A conventional PC
with Operating System
>
Requires significant
local processing power,
memory and disk storage
>
Stripped down
Operating System
>
Manages initial start-up
and connection to the
desktop server
>
Decreases initial cost of VDI, but can increase ongoing expenses
>
Open-source software to strip PC down to bare bones is a major effort
>
Testing configuration across PC hardware platforms to develop a deployment
methodology is time-intensive
>
PCs need constant software level maintenance, regular OS patches, and updated
antivirus software
>
PCs have an average lifespan of 4 years; a repurposed PC has the same
hardware and same lifespan
>
Repurposed thin client PCs require more maintenance than a dedicated thin or
zero client
>
Media ports and hard drives are vulnerable to security breach, thin client software
on top of an operating system is still susceptible

More secure than a PC, no hard drive or removable media ports so users cannot
install unauthorized software
>
Requires higher skill level of IT staff for deployment and maintenance, may
include training and outsourcing costs

Thin client vendors charge recurring maintenance fees for access to firmware,
client OS’s, and patches

With PCoIP zero clients we are never scrambling to repair
someone’s computer.
