XenApp Review
Provides ICA protocol performance and adaptive user constraint.


Valuable Features:

  • ICA protocol performance on a slow network
  • Adaptive user constraint in a different user environment
  • Load balancing and HA

Improvements to My Organization:

  • This product can reduce the cost of a user environment, but only if all components are included for a migration to a Citrix environment. 
  • A Citrix environment can increase the security by centralizing and controlling the user environment.
  • The application deployment was also accelerated.

Room for Improvement:

Citrix needs to ameliorate their administrative panel and provide a tool to add more control in the user Citrix environment. An example is Norskale, recently acquired by Citrix.

Use of Solution:

We have used this solution for four years. We used Citrix XenApp when the product was called Presentation Server.

Stability Issues:

There were some stability issues, primarily with printers and some device drivers. It's important for an administrator to configure policies correctly to prohibit some devices from connecting.

Scalability Issues:

We did not encounter any scalability issues. However, scalability is the key to user performance. The administrator needs to check performance counters to ensure the best user experience.

Technical Support:

The technical support is adequate.

Previous Solutions:

We used Microsoft RDS, but it did not have the same performance as the ICA protocol. It lacked the load balancing and high availability functionalities.

Initial Setup:

The initial setup is pretty simple, but you need to follow the manual as with any software installation.

Cost and Licensing Advice:

Beware! It is expensive. You need to include all variables when you are going to migrate your users or applications to a Citrix environment. Remember to establish a global strategy.

Other Solutions Considered:

We did not evaluate any alternatives. Other products on the market lack the same functionalities.

Other Advice:

  • Keep calm and take some time to install, configure, and optimize. Test with users as well.
  • Remember to keep your users in the project loop before releasing the architecture into production!
Disclosure: I am a real user, and this review is based on my own experience and opinions.
