If I was to adopt these ARM instances in production, for my services running on the JVM, I suppose I need to ensure things can actually build, integration test it all together, load test it, and review performance metrics. Then I also need to ensure that all the tooling I use (for example - agents running on the box, other processes decoupled from my service, etc) are all working as expected without functional or performance regressions. I’m actually not sure what else needs to be looked at... but this is all new work without new value if I look at it on its own. Hard to justify to my CIO. I don’t know what the pricing model is but I wouldn’t even think of adopting this unless there’s a significant price benefit, allowing me to run on much cheaper hardware. Even then, it only makes sense to me if you have hundreds or thousands or tens of thousands of hosts provisioned where that price delta really adds up to savings. This is all conjecture - I’ve never done a migration like this.
