I've been seeling a cost-reduction service for a while, and the hardest aspect of selling it is that so many people on the tech side doesn't care because they don't seem to be held to account to the drain they cause.
I can go in and guarantee that my fees are capped at a few months worth of their savings, and still it's a hard sell with a lot of teams who are perfectly happy to keep burning cash.
And I'll note, as much as I love to get people off AWS, most of the times people can massively reduce their bill just by using AWS properly as well, so even if bare metal was bad for their specific circumstances they're still figuratively setting fire to piles of cash.
