I was a guy that built server clusters during the early 00's, for my own and others' web and other projects. When AWS really took off, it was like a spend all your money mania, and devs and companies treated my skills like dirt. I got a job writing facial recognition edge servers, with high performance many claim are impossible numbers (25M face compares per second per core) and my employer found itself a leader in the industry. But customers could not wrap their heads around just a single box capable of our numbers (800M face compares per second, plus ingestion of 32 video streams) and to get sales the company ended up moving everything into AWS because customers did not trust anything else.
