This. We have three people entirely dedicated to reducing costs.

As for avoiding ARM, we do only x86-64 because corporate security policy demands that we have Windows laptops so that some box ticking overlord can fill out a security policy compliance form. That means we're stuck limping along with docker and WSL2. Every single engineer in the org has an arm64 machine at home already and wants a proper computer at work, which can ironically work in the same policy framework if anyone gave enough of a shit to deal with it.

So that's why we don't use Graviton; corporate security policies. Our customers will just have to eat the price hikes.
