How much RAM and Disk do you have in Prod?
I was talking to a friend and said there aren't _that_ many companies with the scale to truly justify FAANGesque solutions. I've only had two projects where a server couldn't just hold all hot data in 256gb. For most, services I've seen, a laptop + hard drive would suffice.
I'm curious how big the DBs you touch are, how much ram all your microservices use or other such metrics.
I don't know, probably need to get finops to run a report to find out. More than 256gb but scaled out. Don't need a single virtual machine with that much for most things.
I imagine you rarely need a lot of RAM like that on one machine except for ML and some specialist stuff. Maybe a CDN node. Not sure.
For mixed workloads, I find that memory becomes the bottleneck first for running workloads on a given physical host. This changed after NVMe SSds became available – before that it was disk I/O.
But pricing per GB is also a factor I have to admit, currently we are outfitting with 1.5 TB memory per CPU.
The responses will self-select for people with trivial requirements. Nobody with real resources will divulge what those resources are.
why would they not?!

this is HN, there are more throwaway accounts than “real” ones
