Many organisations are looking to refresh their desktop model and at the same time consider deploying a virtual desktop solution. This refresh is likely to be the first time the desktop has been upgraded in five or six years and with the increased complexity of evolved applications during this period, the correct approach can seem even more daunting.
A Gartner research paper recommends the deployment of Windows 7 should be conducted over a twelve to eighteen month period. With the addition of virtual desktops the project may seem like an impossible task.
However, with the pending end of life of XP, and the increasing user expectation to move to Windows 7, replacing the existing desktop operating system will have to happen in the near future. Virtual desktops are also becoming a necessary requirement for all businesses to improve flexibility.
Monitoring the physical desktop environment for a period of time, ideally at least thirty days and over a month end, provides a clear view of how the VDI infrastructure should look. This approach improves the transition time to the virtual infrastructure as it removes the guess work involved in previous migration projects.
Matching the users to their required desktop builds addresses their performance requirements and ensures the correct physical hardware is sourced and configured to meet the business needs by providing the best user experience.
This approach will also ensure all applications are compatible with the new infrastructure and that the users and applications are tiered and grouped to meet business service levels.
By aligning tier one vendors (HP, Citrix & NetApp) ensures the whole solution is compatible, resilient, performant and from proven and trusted vendors.
Our approach is to follow our engagement methodology which encompasses all aspects of a project.
We will firstly monitor the production desktops for a month or two to understand how the new solution should be architected. We will also categorise the users into desktop groups based on their requirements and then tier the applications for compatibility testing. The deliverable would be a high level design with costs.
We would work with your organisation to define a strict set of testing criteria, build a proof of concept environment and ensure all criteria are met. We would amend the design to meet your needs and tailor the users’ profiles to improve security and performance. Further user acceptance testing would be conducted on a group of pilot users to ensure any further possible concerns are highlighted before the final migration. The deliverable would be the final detailed design and build documentation.
Once these tasks are complete all that remains is to migrate the remaining users to the new infrastructure in a controlled manner. Test criteria will be set to ensure no functionality is lost during the migration. The deliverable will be a fully migrated desktop environment.
The final stage is the ongoing support and associated services. We are able to provided dedicated technicians to regularly monitor your environment and be on-hand to provide assistance in day-to-day tasks or resolve first and second line support queries. We will also maintain and update build documentation.
