Expanding the Tau VM family with Arm-based processors

I'm glad to see this, but I'm disappointed that this tops out at 48 vCPUs. The equivalent from Amazon has 64, and Altra processors support up to 128.

Are those a lot cheaper? A cursory look at the pricing page puts them within 25% of x86_64 hardware.

People tend to cite convenience as the number 1 reason to use the cloud, costing more money in renting fees but less money on dev&ops staff man-hours. Is it really worth adding the complexity of multiarch on the staff to get some of that cloud money back?

It's not multiarch if you develop on Mac.

That's a good point! I came here from the other HN submission about hybrid Kubernetes clusters, I guess that's what I'm really wondering about.

Ampere Computing seems to be a "fabless" semiconductor company. I wonder where the chips are manufactured?

Probably TSMC - https://www.anandtech.com/show/16979/the-ampere-altra-max-re...

Google is late to the game on this one. AWS already has Graviton3 / Neoverse V1 based VMs rolling out which are substantially faster than Neoverse N1.
