AWS Outposts is the solution. I like Oxide but people seem to be blind to the actual competition when they focus on Dell as the competitor. AWS has been shipping Outposts racks for years. All prices are public on their website and you can order it today. Nearly every configuration is sub-$500k. Fully managed and AWS supports the entire stack; no buck-passing among vendors, same as Oxide.
I’m not sure where his customers are, but Outpost up/downlinks are supposed to to be at least 1gbit, and they don’t behave well in situations where the latency to the paired region is high. EBS lazy loading blocks is great in region but awful when your ping is 300ms.
