MCS – In all license models
PVS
XenApp Platinum
XenDesktop Enterprise / Platinum
Citrix Provisioning Server for Datacenters
MCS- virtual infrastructure
PVS
- Redundancy
- Network infrastructure (tftp, PXE )
- Each PVS server must have identical VHD files
PVS - Write Cache in RAM with overflow to disk
MCS - local SSD ? Central storage
Desktop Catalog models
Flexibility & Agility
MCS
- Updating image can take time (depends on the storage)
- Limited version management
PVS
Maintenance PVS infrastructure
Platform
PVS
PVS – VM & physical
MCS – VM only
Do we really want to
set the clock back to 2004 ???
- Software streaming technology
- Network based solutions & Boot Loader + TFTP
- RAM Cache with Overflow to disk
- 1 PVS server to 1000 target devices
Challenges :
- Distribute the vDisk
- A separated infrastructure
MCS
Easy to install
MCS- one easy wizard
PVS
- A separated infrastructure
- A dedicated server
- DR consideration
- SQL Database
- Network Configuration
- Single disk image – (not linked clone ) and disk use diff disk
- Simplicity – Not additional configuration on united console
- Storage based solution
Challenges
- storage
- scale-out
- full image copy to each datastore *

PVS
- Version management from the console
- Target device can load in read write/ test / PROD version
- Change can complete immediately (depend on replication system)
MCS
- Version management based on VM snapshot
- Change can complete only after full image copy to each datastore
Single image delivery
It really saves time
