The thing about VDI is that you can't underprovision the client, but you can underprovision the server to a resonable extent. I've seen deployments who decide that it's a great idea to give Windows 10 VMs 2GB of RAM and 1vCPU, which turns the instance into a swapping mess. However if you give the users suitably sized VMs (e.g. 8G/4vCPU) then they will have the burst capacity for faster application loads and such while the server can remain overcommitted (it's rare that all users will need to use up all their vCPUs and memory at a given time).
However for doctors there may be another option aside from VDI, which is RDS or similar where a single Windows Server instance handles multiple remote desktops. Sort of like multiple users using SSH to connect into a shared Linux server. Unlike devs they can rely on a fixed image and don't need to make global changes, making a shared instance viable. This would allow the users to make better use of the compute resources on the server.
> So long as Citrix isn't under-provisioned, which is all too common.
A common selling point of Citrix and similar solutions to the CEO is that by centralizing and sharing resources (CPU, RAM, etc.), we can save money on redundant, unused capacity - on most user workstations, the process which clocks the most CPU time is 'Idle', after all!
Nah. VDI is in many environments the biggest compute system in the datacenter. Peoples work patterns are very consistent so there typically isn’t much slack.
The top issues with VDI are memory availability and profile management. As CPU improvements stopped, apps are memory hogs. With a modern Microsoft stack, even basic users run Outlook, Teams and Chrome. Outlook is usually caching too much, so your virtual desktop with OST stored on a shitty NAS somewhere is essentially a really really awful single user Exchange server.
What is that in response to? You're saying VDI isn't slow and underresourced for many people? Perhaps that's not your experience, but does that mean it's not the experience of others? Are you saying that VDIs aren't sold that way to CEOs? I've seen it and the underresourced results multiple times.
