I want to know best practices of segmenting user vlans in a virtual desktop platform.
Say I have a user department of 1000 users and they use same golden image...should I keep them in single vlan..subnet or multiple.

Second scenario is I have one golden image used by three departments..some of applications used by one department should not be accessible to other department although it's there in golden image..I don't want to maintain multiple images..for those few web apps..currently in physical desktops since these departments sit in different vlans ..we have firewall rule which prevents traffic from that particular vlan...what I want to know in VDI scenario,what's best way to do this segregation...

Using vLANs will add complexity in a PVS environment. PVS servers using option 66/67 will not be redundant during TFTP/PXE because you can only add 1 server in that field. Additionally you have to worry about DHCP IP helpers configured for each network segment. Instead use PXE broadcast, and have all VMs in same subnet as PVS servers. I don't see a reason why separate the users, since they are sharing a single image.

Sharing apps in single image can be prevented using MS AppLocker policies at a minimum, there are other 3rd party solutions like AppSense as well.

brainstomer...we are a financial institution and as per current security guidelines..even though if some users share same golden image..we would need to prevent some user groups from accessing certain web based applications used by other departments..currently in physical desktops its done by having firewall rules from a particular floor VLAN to the app servers of the application etc...Also we don't want to have a flat network so we don't want all vm's to have a single subnet and instead prefer to have vm pools having different..because in case of a security threat we don't impact all desktops at once and also to avoid broadcast storm

In that case I would recommend a pair of PVS servers for redundancy on each vLAN, setup as sites under the same PVS farm. The same gold image can be shared among all PVS servers.
