When it comes to building a mousetrap, what's the first thing you think of? Chances are, you do not think the wire gauge you will use, or voltage levels for the springs. If you're like me, you think of the mouse basic needs, and how you will deal with in order to attract the mouse to its new "home." What mouse need? Food, water, shelter, etc.? Regarding the design of a virtual desktop solution, we too often see the opposite. People are starting to design a solution by identifying the server hardware and storage infrastructure and design from there. Cores and IOPS, memory and network throughput. But we forget the basic needs of persons for which this environment is designed and built; end-users. To attract end-users of the solution, and ensure they get inside, you have to start with the end user's requirements and work until you reach the hardware requirements.
At Citrix Synergy 2013 in Anaheim, California, Niraj Patel and I presented a session on best practices and methodologies to consider when designing a virtual desktop solution. Here are some of this presentation design considerations:
When we think of virtual desktops, consider the environment in five layers:
User Layer Endpoints and end user functionality required such as multimedia
access layer: connection between end users and their virtual desktops
office layer: Virtual desktops, applications, profile, personalization and policy
control layer: controllers infrastructure necessary to support the environment
hardware layer: physical devices; servers, storage and network necessary
As a design principle, starting with the user layer and work your way down. Identify the needs of users in terms of application and functionality requirements which devices they will use, and how they will access the systems. Group of users based on this information, and the group of applications as well, so you can map applications to users. Users and groups mappings should be in place during the evaluation phase so that appropriate design decisions can be made during the design phase.
Once the user-level design decisions have been set up, move down to the access layer, and to determine how the user access needs will be addressed in the design. groups of users accessing the local environment or remotely (or both) are they? Will they move and use multiple devices such as tablets and smartphones in the enterprise environment? What policies access should be implemented? These are just some of the considerations. Once the design decisions on the access layer are determined, we can set the access layer elements such as StoreFront NetScaler and Access Gateway are needed.
Similarly, continue through the desktop layer, identifying decisions around personalizaton, profiles and workstations, and down through the layer control, identification of needs design scalability and control element. Once you have it all together, you can put together the requirements for equipment, given the overall design in terms of modules and scalability.
The top-down approach lets you design the solution from the same state of mind that users who access it; endpoints for desktops or virtual applications running on the hardware in the data center. Doing this will help to ensure that user needs are foremost in mind during the design process.

Updated :. Regarding the design of virtual desktops, Citrix provided a very good tool to help in the process; accelerator project. Project accelerator has recently been updated to provide design tips, as shown in the recent blog post from Chris Pagel "Ready, Set design!" This is an excellent tool to use to start your evaluation and design efforts for virtual desktop environments. Check it out!
