Desktop Virtualisation with VMware Horizon View

Desktop virtualisation is a relative newcomer to the virtualisation arena but is an old concept. There are many benefits to virtualising desktop computers including:

  • Centralised management
  • Easier upgrades and deployment of new computers
  • Better security options
  • The ability to isolate difficult or legacy applications

VMware View offers a fantastic platform for centrally managing and deploying your virtual desktop computers. Like infrastructure virtualisation it is critical that current and future utilisation be taken into account to avoid performance issues. Other elements such as hardware compatibility and licensing must also be considered.

KN3 recommends the following approach to your desktop virtualisation project:

    Discover and Understand

    The first phase is always to discover and understand the existing environment.

    Key Steps:

    • Hardware and Software
      • Computers are audited using agents to capture hardware information
      • Application utilisation is assessed either using tools or manual interviews
      • Computer processor, storage and disk utilisation data is captured
    • Investigation
      • Which applications currently actively in use (as opposed to just installed)
      • Which applications are required and of those which are key?
      • What is the position with licensing, are the applications and operating systems adequately or even over licensed?
      • Which hardware is being used?
      • Which resources are currently being used (disk, memory and processor)
    • Analysis
      • The application list is analysed either as a complete list or by logical grouping such as site, department etc. with a view to understanding the real requirements
      • Candidates for rationalisation such as multiple versions of a product or products with low utilisation are identified
      • If application packaging or virtualisation is required the applications are categorised into type (easy, medium, hard)
      • Licensing analysis can also be performed
      • Desktop types are specified to cover the most common usage
    • Compatibility Checks
      • If an operating system migration is also planned it will be necessary to check whether each application functions and is supported on the target operating system
    • Reporting
      • A full report of the existing environment and the recommended approach is provided

    Design and Implement

    The second phase is to design, prove and implement a solution.

    Key Steps:

    • Standards Definition
      • Standards for the installation types (operating system, software and patches) need to be defined and documented.
    • Solution Design
      • The virtualisation enviroment is planned taking into consideration the information gathered in the discovery phase and new/future requirements. Backup and availabilty are considered.

    Training and Support

    Phase three ensures that your new solution is more easily adopted and supported.

    Key Steps:

    • Training
      • Support personnel will need to be trained on how to manage virtualised servers and networks
