Among the many benefits of running @bitfinex outside of AWS (predictability of the system, performance, ...), we were sick tired of AWS rebooting instances without much of a notice.
In many occasions AWS sent a communication after the fact.

I hope you weren’t using spot instances to run your trading engine ;-)
Of course not. Still voodoo s*it was happening all the time.

I agree, AWS doesn’t seem to have live migration figured out as well as others. I do wonder how much effort goes into having your own infrastructure as reliable as AWS, especially in disaster scenarios. But I’m sure you guys figured it out, and it’s very cool you made it work

We have built our systems around shards and replicas on a bare metal setup. We can resist to 2/3 of the servers dying and we have also off-site realtime replica on a separate infra waiting in idle.
