My understanding is that S3 egress is only a problem if you need to take data out of AWS, which you can simply avoid by having some kind of dedicated AWS direct connect or some such to route the traffic yourself?
If I'm reading the description correctly, egress from there is 2 cents/GB, while the regular price for egress (less than 10 TB) from eu-south-1 is 9 cents/GB.
I was pretty sure there was a way to have something that's just a fixed cost, maybe with a partner third party service.
