Qlik Sense and server virtualization


Qlik Sense and server virtualization

There are several considerations to make before installing Qlik Sense in a virtual environment:

  1. Run virtual environment on previously tested hardware for best possible conditions: 
  2. List of Favorable Server Hardware from Qlik Scalability Center
  3. Evaluate what hypervisor (virtual machine monitor) settings provide the best performance
    • Beware vertical scalability limitations of ESX v3.5
    • Memory management such as Transparent Page Sharing and Memory Ballooning may cause instability in the guest system and should be avoided. It's recommended to configure the virtual machine to use static memory allocation.
    • Dedicated Resource Pool is required for optimal performance
    • Useful for Change Control Environments and Disaster Recovery. Discouraged in Production
    • Virtual environments are slower compared to the physical computer due to overhead of the hypervisor used
  4. Validate that production applications perform as expected
    • Acceptable applications performance on user interaction 
    • Compare performance if the application is run on a non-virtual server
