Specing out Perspective hardware for new project

[bkarabinchak.psi]

I was reading this article - Ignition Server Sizing and Architecture Guide | Inductive Automation

It was very helpful but it does not seem to delineate even mention Vision and Perspective until the very end when it's talking about a dedicated frontend server which this will not be having. So this part -

Is it safe to assume when it says 10 concurrent clients it is referring to perspective since Vision uses the resources of the computer it is running on when possible? Or is this for vision?

The new project will have 1 PLC attached to a ignition gateway, something like 500 tags on historian, and 10ish perspective clients. Based on the article that seems to suggest 16 Gigs of ram (I added more for the db) and 2 or maybe 4 cores. Certainly seems like enough at a glance but I just wanted to see how "concurrent clients" should be interpreted here and for opinions here on the hardware.

See this recent topic:

Microsoft Virtual Machine Suggestion

After going through that sizing guide, I'd add another vCPU for every 4-8 Perspective clients (of pretty much any kind), a GB of gateway RAM for every 4-8 light-duty Perspective clients, and 2-4GB of gateway RAM for every heavy-duty Perspective client. "Light duty" would be single page Perspective apps running in Workstation, or Mobile, or single-tab browser sessions, displaying dashboards with real-time tags, up to an hour (-ish) of real-time trends, and pre-computed statistics for longer time…

No, the guide clearly is meant to cover the much lighter gateway workload even really busy Vision clients produce.

Yea I got the inkling it was talking about vision as well. Thanks for the link and info!
