There is no hard and fast rule on this but Mike's information around
performance/resource (from 2019) may be of use:
"...we found that you will generally need 1 core and 2 GB for every 25
concurrent users at peak. Exceeding that will not cause things to fail,
but users may start to notice performance degradation. This is mainly
relevant to the server/cluster hosting guacd. We did not encounter a
need to increase resources for Tomcat or the web application, even after
exhausting our ability to generate simulated load (~2000 users)..."
Things have moved on a little since then but the above is probably a
good place to start (thus suggesting you'd need to allocate around 2
cores and 4GB of memory for your proposed use).
Other users have posted information on their resources, including those
with 1000's of users, but one of the next closest to you would probably
be Dennis Newman who noted the following in 2020:
"1 - production web server
1- Guacamole Server - running on a CentOs7
Set with
8 virtual CPU
16 gig Memory
a 100 gig Hard disk
and 1 virtual Nic
40 virtual windows 7 desktops being connected through Guac RDP
Server 2 is an HP ProLiant DL360 Gen10
With Dual Intel(R) Xeon(R) Gold 5218 CPU @ 2.30GHz
and 580 gigs of Ram currently hosting 65 Virtual systems
1 Development Sql server and 64 virtual windows 7 desktops being
connected through Guac RDP
We have also added 75 new Guacamole RDP to Physical desktops (mostly
Windows 10) since Work From Home began.
ESXI Hosts are using about 20% of theis CPU resources
We are sitting at about 50% host memory usage
My Guacamole system averages about 30% memory and cpu usage to
allocation..."
