You can order bare metal servers delivery time in minutes from any number of hosting providers and the cost difference is so huge you can afford to keep excess capacity and still come out ahead.
I run the CI infra for our company, and our bare metal costs (sans my salary baked in), are one order of magnitude less than if using any other CI saas provider like github or others.
Like literally 10x times more expensive to do so, to run CI jobs...
I dont want to imagine the margin AWS has like generally, cause it can easily be a 90% too
Right? It's actually crazy how much they don't cost. Are you using it more than 10%? If so, you're saving money.
I assume you're using your owned server and not a provider like Hetzner? So you did have a substantial delivery time. Although in my city is a recycled that resells used servers, and I could show up there with a truck and get a server within hours if I'm not too picky. Or use some random desktop or laptop off the pile, short-term.
