Step 4: Categorize Users
Published: February 25, 2008
At this point, the list of users as well as their applications that will be hosted by Terminal Services has been validated. In order to properly size the Terminal Services environment, the load that users will place on it needs to be understood.
The implementation of Terminal Services will involve a significant change to the way that an end user’s applications are run. The applications will execute in a shared environment on a remote server rather than on the user’s dedicated local workstation. In planning for such a change, it’s unrealistic to expect to calculate the precise resources required. Instead, try to estimate them as closely as possible and provide some additional capacity in the system to compensate for any spikes in usage that may occur.
In order to do that, place users into one of three categories: Heavy, Normal, or Light, based on their general usage behavior in their applications.
This categorization will be used in step 7 to provide the user load on each application as input to determining the size of the terminal server farm.
Assign each user, or group of users, to only one category since the categorization is reflective of behaviors that are likely to be the same in all applications.
Place users into the following categories:
Users have now been categorized according to the intensity with which they use the applications to be hosted. Each user has been marked as Heavy, Normal, or Light intensity based on the way they use applications. This categorization, and the number of users falling into each one of the categories, will be used in step 7 to provide the user load on each application as input to determining the size of the terminal server farm.
The next step is to determine how many terminal server farms are required to deliver the applications.
