Hard disagree. You can have incredibly complex infrastructure (whose maintenance necessitates an FTE) running on a single VPS. Some of the smartest infra consultants I've met have point blank said "you shouldn't implement a fleet of cloud microservices for that, I can implement this whole stack on a single machine if I'm efficient about the architecture and underlying algorithms."

My point is that none of these coworkers have ever been at that stage. He was surprised about me hosting something because he seems to think hosting is expensive and for companies. Straight in at the top end of k8s and microservices
