Cool. Glad you took the time to correct me.

I run a SaaS and spend a few thousand per month for my hardware and software. And I wouldn’t want to spend any less and reduce my footprint,

I was not correcting you, just stating that for most solo entrepreneurs, the running costs are close to zero, usually unless your service handles intensive data (images/videos) or decide to spend the money on paid hosted solutions vs hosting open-source alternatives.

why do you have to spend a few thousand?

Why not?

Zendesk alone is over 1k. You can use a fake help desk software for half, but is it worth screwing with the bugs?

My CPU load is something like 200 CPUs 24/7, and needs to be fault tolerant on top of that. Also needs to run without a sysadmin on my side.

why such a high cpu load?
