Which CPU, RAM, disk space should I use? And how many clients per server?

As a start-up package, the virtual machine with at least 4GB RAM and 2xCPU is required.

Disk space doesn't matter. 10 GB would be enough to setup the host OS: Ubuntu Linux 18.04. SSD drive is recommended.

This server can run up to 200 online clients with logging, and up to 1000 online clients without logging (you can still turn on logging for test configurations).

For larger amount of clients, you can use a dedicated server with 16Gb RAM and 6xCPU and 250Gb SSD drive. Such server may host up to 2K online clients with logging, and up to 10K online clients without logging.

Here are two real examples.

1. The dedicated server Intel Xeon E3-1240 3.4 GHz 4 cores, 16Gb RAM, 220 Gb SSD is carrying about 800 devices (production mode, no logging), and this uses less than 10% of the server resources.

Such server should be able to carry at least 8K mobile devices.

2. The virtual machine 2 x 3.6 GHz CPU, 8 Gb RAM and 30 Gb HDD is carrying about 200 devices in production mode within more than 2 years (large database history), and this uses about 40% of the server resources.

Such virtual machine should be able to carry about 500 mobile devices.
