We had a chance to test these with KeyDB and the performance was quite good. It’s definitely a viable alternative to Intel and AMD instances.

Keep in mind the AMD instances are using chips AMD put out almost 3 years ago. They still aren't using the new generation of Rome chips that came out a year ago, which almost doubled performance.

C5a instances are coming, and I think that you'll still be pleased with the price/performance of M6g instances for a wide variety of applications. But if your app works better on AMD, or on Intel, we want to give you a broad selection so you can achieve the best result given your specific needs. Cloud makes it easy to switch.

We’ve been quite pleased with AWS’ t3a offering and have saved quite a bit of money by switching. We did encounter some odd kernel panics early on, but they seem to have stopped.

We’re excited to start evaluating AWS’ ARM offerings, but until now, they would’ve been more expensive for our workload. We’ll have to see if that’s changed with Graviton2, but I suspect AMD is the sweet spot for our application; it just doesn’t seem to like ARM as much.
