After flirting with the idea for a month or two, I’ve switched Bigdinosaur.org (and the sites I’m hosting) over to a t4g.medium EC2 instance, which means we’ve finally left the universe of x86 and x86-64 behind—at least, for the hosting stack. This serves as a great trial run for next May or June, when I’ll be switching Space City Weather and The Eyewall over to Graviton once the existing reserved instance for those sites runs out.
It’s working great so far, primarily because all I really need to work is Ubuntu, nginx, MariaDB, redis, and php—and, fortunately, all of those things are available to install on ARM CPUs. The switch was no different from any other server migration I’ve done before, and I’m very happy with the results. (Knock on wood!)
