You're forgetting the cost of fighting IT in a bureaucratic corporation to get them to let you buy/run non-standard hardware Much easier to spend huge amounts of money of Azure/AWS and politely tell them it's their own fucking fault when they complain about the costs. (what me? no I'm not bitter, why do you ask?)
They seriously can't buy a graphics card and slap it in the PCIe slot?
Any buying requests go through the direct supervisor, the financial department, the director of the company, then back to the supervisor for the final signature. And because it's Germany, it was on paper. When I say any buying request, I mean any. From any programming book, to any accounting book for finance or any HR book.
You'd think people at the top have better things to do. You think that, until you hear the department heads discuss which excel format files should be saved in.
