Having this on AWS is perfectly fine. I even think it's viable to look at Hyper.sh as an alternative to Elastic Container Service, even though both are being hosted on AWS. But if it's hosted on AWS, it's important that people actually know that. If someone wants to build a highly reliable system, and they pick 2 resources -- let's say Hyper.sh and AWS ECS as the most likely candidates for that -- it's pretty important for the customer to know that both resources they're relying on are on the same service, and even possibly in the exact same data center, as that affects how effective their redundancy actually is.
As another side of the same point, hyper on AWS shifts the balance of costs for me as if I want to store my data in S3 it changes whether or not I've got to pay for network egress.
