alt Hacker NewsJoe Schmoe LLC will probably do just fine by sticking to popular clouds. I reckon adopting Oxide Computer would pay off at much larger volumes of traffic, or if you have to do on-prem due to regulatory reasons.
It would be nice to know more about pricing so the Enthusiast Joe can have a better idea, but it's more a boutique vibe right now.
Putting together bits and pieces from different sources: a half-rack is the minimum SKU, and it has 1024 cores and 16 TiB RAM for somewhere around $600k. (So many people have repeated the latter number that it must be true! I.e., add salt grains to taste.)
Just the thing for an ambitious enthusiast to upgrade to from their Raspberry Pi rack!
