On average, it looks to be less than 2gb of ram at the moment. CPU and RAM usage obviously will go up as I have more users, but it’s not bad at all at the moment. I’ve been pleasantly surprised tbh. I am also completely prepared to scale the server up if I get more users on my instance.
Edit: just a follow up, looks like I can scale my instance to a maximum two ways,
“cpu optimized” up to 48 vCPU and 96gb of ram
“Memory optimized” up to 32 vCPU and 256gb of ram
I’m a long way off of the max though now, my server is only 2 vCPU and 4gb memory for now
