how calculate the resources of a VM (CPU, RAM) in function a users number

[Daniel Ceballos]

Hello everybody

I'm new in this community, i just wanna know if there is a mathematical formula for to know what is the perfect amount of resource (CPU, RAM)   according to the number of users that use my server.

I don't know if you understant that i mean, (sorry for my english, i´m spanish people) , anyway, the number of usuers in the university server (moodle) is very diverse acording the date. so, if i know the optimous size of resourse, i wouldn´t  have idle resort (recurso ocioso). becouse that means money.

tanks for your the atention.

PS. againt i apologize for my english.

Hello Daniel,

Unfortunately, there is no such formula to figure out the exact resources requirement. I would recommend you to use the monitoring tools eg: Stackdriver for monitor, logging and diagnostic purposes. You can start with the smaller machine type and depending upon the usage and load on the VM instance, change the CPU and memory later. More information on changing the machine type of an instance can be found at this link.

I hope this information helps you.
