RDSH vs. VDI comparison proves use case is everything

In a RDSH vs. VDI comparison, it's not a matter of which is better. The most important thing is which one best fits your use case. VDI is good if users need multiple applications, but RDSH is a more lightweight model.

There has been a longstanding debate on which is better: VDI or RDSH. Ultimately, the verdict is based on use case.

Whether virtual desktop infrastructure (VDI) or Remote Desktop Session Host (RDSH) deployments are better depends entirely on what and who you need to support. Coose VDI if you have more complex needs, such as multiple applications per session and advanced performance. Go with RDSH for simpler models.

RDSH and VDI comparison

RDSH is a shared-user model. If your end users need to be completely separated from other workers' sessions, or they need their own desktop instances, then choose VDI. Additionally, if workers need access to local, virtual, streamed and Web-based applications from the same operating system, then VDI is the answer. With RDSH, users will typically only access RDSH-based applications installed on the farm, which can be limiting.

And RDSH performance is constrained by what the server can supply. But with VDI, you can give users as much CPU and memory as they need. VDI also supports more advanced graphics use cases, and it allows for more third-party peripherals than RDSH commonly does.

If users only need to stream a single application, then RDSH is the easier and cheaper method to deliver it. RDSH is also a much more lightweight option than VDI because all users share the same Windows Server, so the RDSH environment doesn't need as much memory or CPU to handle its user base.

Both VDI and RDSH can help in different situations, and it's up to the architect or administrator to determine what their users truly need.

Which suits your needs better: RDSH or VDI?
I beleive that you missed a use case here and something that i have used quite extensively over the last 10 years, a mix of VDI and RDSH. For heavier weight applications that you want to segrated from VDI or that VDI cant handle, use a mix of the 2. This allows for more users to accept a VDI solution that gives them better perfromance than a physical desktop would
Hi magsdtev -- thanks for the comment! You're absolutely right -- it's a great idea to use VDI and RDSH together. This piece of content is an AtE (Ask the Expert) so it's meant to be short and answer one particular question. In this case, the Q is whether VDI or RDSH is better. The answer is that it depends on your use case, but that in no way means people should have to pick one or the other. Using a blended approach is the right path for some shops, and like you said, it helps get more employees on board with virtualization than VDI or RDSH alone could.
