New Campus, No Lab Space
• In 2010 the Michael DeGroote School of Business added a new campus building in Burlington
• No student lab space was allocated • Students needed to access their course
required applications• UTS was asked to help find a solution

UTS Expands Citrix Farm
• Decision to leverage existing infrastructure
• UTS managed a Citrix XenApp 4.5 Farm provisioning financial applications for Budgeting and Human Resources.
• Added 2 XenApp servers and new licenses
extending the farm for RJC Students

Typical Lab Desktop Installation
• Use some type of imaging software to install each PC with identical software
• Problems arise with software compatibility, dependencies and multiple versions.
• ** Riley to edit…

Citrix Published Application• Applications are
installed on the Citrix XenApp servers and then accessed using the client browser.
• Allows for remote access.
• Still have problems with software compatibility, dependencies and multiple versions.

Streaming Application Installation
• Applications are packaged and stored on a file server and streamed to the XenApp server eliminating problems with software compatibility, dependencies and multiple versions.

Performance
• Usage Patterns for concurrent use• Split between evening and day students• Labs with 50 students all logging in at once• Required to use Windows 2003 32 bit
![Page 10: McMaster Lab Virtualization UTS and Ron Joyce Centre.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d565503460f94a33eca/html5/thumbnails/10.jpg)
Continued Support
• Semester turnover• Adding new applications• Updating existing applications• Citrix Client installation• Managing user accounts
![Page 11: McMaster Lab Virtualization UTS and Ron Joyce Centre.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649d565503460f94a33eca/html5/thumbnails/11.jpg)
Lessons Learned• Add user account management to faculty as
much as possible• New Citrix Clients must be tested!!!• Citrix support issues for MAC or Linux• Different browsers behave differently • Once initial setup is complete – very stable
and few problems

Lessons Learned Continued
• Application specific licensing• Difficult to get applications tested• We are not ARIS experts, need cooperation
with faculty• Some applications more difficult to virtualize
