I'd like to see Amazon offer some new services to improve working across multiple regions.
Just being able to copy an EBS volume and AMI to a different region with a single API call would help a lot of people quickly establish much better redundancy than they had a week ago.
Yes, better support for running in multiple regions is clearly needed. There needs to be native support for transferring snapshots between regions (at the user's expense, of course).
Almost need an availability zone built for a failure event that otherwise sees little use, or just spot use. So then you can assume that the people on it need the same resources their live implementation is taking up before failure so there is no overload when the failure occurs.
That would mean a 25% price hike on all services. Rather a lot for a situation when the biggest issues seem to be lack of preparedness and planning for failure by a lot of people.
