•  Published Applications and Desktop Sessions by Farm

•  Supporting servers –  License Server –  Databases –  Web Interface / StoreFront

14 CONFIDENTIAL

Published Applications and Desktop Sessions •  Application inventory: perceived versus actual

•  Application demand –  Priority applications –  Applications that can be decommissioned

•  Application requirements –  Supported OS –  Device support

•  Applications by RDSH Server

•  Desktop sessions –  use cases –  configuration

•  Users and groups entitled to each application and desktop session

15 CONFIDENTIAL

Terminal Servers / RDSH Servers •  Inventory:

–  Name –  Windows Server OS version –  Terminal Server / RDSH Server version –  Location –  XenApp Farm membership –  Supporting RDS License Server –  Major system specifications

•  Identify: –  Ideal migration candidates –  Systems running outdated server OS (pre 2008 R2) –  Servers with resource or stability issues

16 CONFIDENTIAL

Users and User Requirements •  Identify Users by:

–  Application and Desktop Session entitlement –  Location –  Use Case

•  Establish User Requirements: –  Remote access –  Printing –  Drive or Communication Port Redirection –  Preferred client devices

CONFIDENTIAL 17

Client Devices and Supporting Systems •  Client Devices

–  Devices in use •  Thin Clients •  Zero Clients •  Mobile •  PC

–  Planned new devices –  Peripherals (printers, USB)

•  Supporting Systems –  Virtual Infrastructure –  Load balancers –  Network –  Storage

18 CONFIDENTIAL

Customer Example #1: Printing Company •  Business Goals:

–  Single Web Portal for SaaS applications and hosted apps –  Support iPad rollout –  Maintain support for legacy printing systems

•  XenApp Infrastructure: –  Version 5.0 –  Two Farms / Eight Terminal Servers –  No web interface or load balancing

•  Published Applications and Desktop Sessions –  No desktop sessions –  Office 2007 suite to be phased out and replaced by SaaS application –  Need to maintain support for printing press control software which requires serial controller –  Printing press software entitled to groups: Printers, Facilities, and TSAdmins

19 CONFIDENTIAL

Customer Example #1: Printing Company (Continued) •  Terminal Servers / RDSH Servers

–  Eight Terminal Servers running Windows Server 2003 (TRMSRV1 – 8) –  Location: Ohio Datacenter –  Physical Servers with two dual core CPUs, 32GB RAM, serial controller card –  Two servers: TRMSRV3 and TRMSRV8 have failing components

•  Users and User Requirements –  User Groups: Printers and Facilities –  Must support access from corporate LAN and WAN (no remote)

•  Client Devices and Supporting Systems –  Must support access from iPad and PCs –  No special client device support required –  No load balancer in use. –  Terminal Servers are physical (no SAN)

20 CONFIDENTIAL

Solution Example #1: Printing Company •  Implement VMware Workspace Portal to support SaaS application initiative •  Keep XenApp 5.0 and 2003-based Terminal Servers to support legacy printing software

•  Integrate XenApp with the Workspace Portal •  Phase out Office 2007

•  Decommission four Terminal Servers (TRMSRV3, 5, 7 and 8)

21 CONFIDENTIAL

Customer Example #2: Law Firm •  Business Goals:

–  Single vendor for VDI and hosted apps –  Support merger with smaller firm that uses XenApp –  Phase out San Francisco datacenter

•  XenApp Infrastructure: –  Versions 6.0 and 6.5 –  Six Farms / 24 RDSH Servers (16 running XA 6.0, 8 on 6.5) –  Two Citrix Web interfaces and load balancers in use

•  Published Applications and Desktop Sessions –  Three desktop session profiles: lawyer desktop, support staff desktop, IT desktop –  Office 2010 and 2013 (2010 being replaced) –  Time keeping software –  Legal research software

22 CONFIDENTIAL

Customer Example #2: Law Firm (Continued) •  24 RDSH Servers

–  Four running Windows Server 2008 •  SVR2008-36,39,40 and 41 •  eight CPUs, 64 GB RAM each

–  14 running Windows Server 2008 R2 •  SVR2008-72 – 85 •  eight CPUs, 64 GB RAM each

–  Six running 2012 R2 •  SVR2012-11 – 16 •  sixteen CPUs, 128 GB RAM each

–  All RDSH servers are virtual (vSphere 5.1) –  Locations:

•  New Jersey (half of the 2008 R2 RDSH and all 2012 RDSH) •  San Francisco (all 2008 RDSH and half of the 2008 R2 RDSH)

–  Customer plans to deploy six new RDSH servers running 2012 R2

23 CONFIDENTIAL

Customer Example #2: Law Firm (Continued) •  Users and User Requirements

–  User Groups: Lawyers, Support Staff, IT –  Must support access from corporate LAN, WAN and remote via VPN –  Network printing

•  Client Devices –  Must support access from all major tablets and smartphones (IOS, Android) –  Must prevent access to local drives and USB-based storage

•  Supporting Systems –  F5 load balancer –  vSphere 5.1 Infrastructure –  View 5.2 for Virtual Desktops in New Jersey datacenter

24 CONFIDENTIAL

Solution Example #2: Law Firm •  Upgrade Horizon View 5.2 to Horizon 6 in New Jersey datacenter •  Deploy VMware Workspace Portal in NJ to replace Citrix Web Interface

•  Migrate New Jersey XenApp infrastructure to Horizon •  Deploy eight new RDSH running Windows Server 2012 R2 to NJ datacenter

–  Two to replace the Server 2008 based systems and six for additional capacity –  New servers will be deployed with Office 2013 to replace Office 2010

•  Phase out San Francisco RDSH Servers •  Decommission XenApp and Citrix Web Interface

25 CONFIDENTIAL

Best Practices, Gotchas, Things to Consider •  Use Workspace Portal to facilitate the Migration

–  Provides “front end” to make XenApp migrations seamless to end users –  First integrate Workspace with XenApp then Migrate to Horizon

•  Choosing the best migration approach –  Is the simple way always the better way? –  Gradual vs. one-time migrations

•  Garbage Out, Garbage In –  Moving problems from Citrix XenApp into Horizon 6

•  Feature & functionality parity –  Wants versus Needs –  3rd party integration may be required to bridge feature/functionality gaps

26 CONFIDENTIAL

Best Practices, Gotchas, Things to Consider •  Common to have multiple XenApp environments

–  Typically aggregated with Citrix Store Front or Web Interface –  Workspace Portal and Integration Broker support multiple farms

•  Hybrid XenApp and Horizon View environments –  In most cases, plan on XenApp sticking around…

•  Should XenApp farms match Horizon 6 with View RDS Farms? –  Application silos and load-managed server groups –  Putting “all the apps” on every server – is this the right thing to do? –  Consolidate multiple XenApp versions on fewer Horizon RDS Farms

27 CONFIDENTIAL

Best Practices, Gotchas, Things to Consider •  VMware Workspace Portal does not support XenDesktop •  VMware Workspace Portal does not proxy or tunnel XenApp

•  Netscaler load balancers can be used for Horizon •  Don’t forget Horizon View maximums

–  Large environments using desktops & applications may exceed Pod limits –  Cloud Pod Architecture currently not supported in HWS

•  Optimize the RDSH Servers –  Makes a difference – implement RDS optimization best practices
