Vertical scaling: 192 core server you can get for $2K per month

I checked different hosting solutions, and the best server is - 192 cores / 384 threads - 1.5TB Ram - 4x10TB PCI4 NVME Storage in Raid-0

This is literally a behemoth. Just rent it. Put all your DB, workers, servers, mailers, on this server.

While that is stupid, feel free to use it as a CI tool as well! Running 384 docker containers in parallel to check all your puppeteer/playwright tests

Bonus point, although grey area - run a monero or similar miner in a low priority to cashback 10% of the server cost.

Now serious question - why would you need microservices, cloud, kubernetes, lambdas and other fun things at all if you can get it working as a monolith just for $2K (ok, let it be $5K with extras) ???
