FlexCast engineering for the end-user David Gaunt Lead Systems Engineer

Agenda

• Managing your users & their expectations

• Why, who, what, how (without the “WTF”)

• Hosted Shared vs. Hosted VDI

• Management headaches and their cures

Users – who’d have ‘em?

End users (they’re customers too!)

• Not great fans of change

• Painless

• Seamless

• Minimal re-training

“I don’t care” “Mmm ports &

protocols! ”

• Smarter management of desktops & apps

Not the band…

The ‘Who’

#1 – IT consumers “I like to work this way”

#2 – IT users “I’ve been told to work this way”

The ‘What’

VM

• Costs less overall

• Easier to manage

• Better performance

• Six-figure scalability

Management Headaches (and their cures)


Complexity is optional

Curing Management Headaches

• Go with what you know

• Separate as much as possible

• FlexCast means Provisioning Services • Single image

• Lower storage costs

• Fewer IOPS

Receiver bits


• Thin client & repurposed desktops • Citrix Desktop Lock

• AutoLaunch “MyDesktop”

• Mobile Receivers • Self Service

• StoreFront with “FEATURED:Auto”

• Hosted Desktops • Session Pre-Launch (6.5 only)

• Tinyurl.com/sessionprelaunch

• Best in 1:1 CCU or U/D
