5 Best Practices for Implementing VDI
1. Segment your end users
No single virtualization approach has achieved universal usage. However, enterprises are currently employing different approaches in an effort to get the desktop challenges under control:
- Server-based desktops using Terminal Services technology
- Workstation-based desktops using VM technology
- Workstation-based desktops running on physical machines such as blade PC’s
2. Use a single standard image for provisioning all virtual desktops
Moving desktops into the data center--
as opposed to managing, supporting, and securing traditional desktop deployments on distributed endpoints--addresses many of the desktop management concerns.
But simply moving desktops into the data center is not a complete solution in and of itself. The solution here is to reduce the number of unique OS images to as small a number as possible—ideally only one. By limiting the number of OS images, you limit the number of places that you need to monitor, update, patch, and audit.
3. Separate applications and desktops
User data and settings are only half the story; users also need to run applications within their desktop environment. While applications can be included in the OS image that is either run directly on a physical machine/VM, or streamed using XenDesktop Virtual Desktop Provisioning, this is not a generally recommended application delivery mechanism.
Some applications are more efficiently delivered through streaming or through ICA. Citrix Presentation Server allows all Windows applications, client-server and desktop, to be deployed in centralized datacenters, where applications and data are less costly to manage and support, best secured, and easier to back up and restore.
4. Develop a strategy for migration from PCs to desktop appliances
For VDI to be fully accepted by end users, it must be rolled out in a deliberate manner to those who will benefit most from a virtual desktop and where the infrastructure is up to the task of delivering a desktop to each user group.
5. Assess the network impact for desktop delivery
With Citrix EdgeSight™ technologies built into Citrix XenDesktop, IT personnel can measure performance and availability from the end user’s perspective.
EdgeSight cuts across organizational and geographic boundaries and monitors the actual end-user experience. This is an essential tool to ensure that the virtualized desktop will deliver a better user desktop than the tradition PC it replaces.
