VPS requirements

hello what is the VPS requirements ?

is 2 CPU Core enough ? for 500 user ? if not so should I increase the space or cores
2 GB RAM
50 GB NVMe SSD
200 Mbit/s Port

This seems too little to handle 500 users. 2GB RAM is on the lower end of things for a single-user account, so you will definitely need more. I am unsure of the CPU requirements, and just stating the number of cores isn’t a good metric.
