Enlightening, thanks. A shame that none of the big names have a data center in South America. I've a project I'd like to bring to Brazil at some point and 300-500ms is not very good. What will it take to open up a node in Sao Paulo or Buenos Aires? Is it lack of traffic or taxes holding up progress?

mix, EC2 just opened a Sao Paulo EC2 data center this week or last week, so you are good to go.

$0.25/GB though so it is a bit pricey.

Unless I'm mistaken, there is now a Cloudfront edge in Sao Paulo, but no EC2 region. This may or may not be appropriate for your project.

With regard to their Regions. Based on this data, you can have really fast responses around the world if you provide your services in all regions. However... It is really difficult to get their cloud services to work across Regions (AMIs not shared, security not shared, RDS, Cloud-formation only works in one region, etc.). If you want to run in multiple regions, you need to use EIBs for your database servers (mysql,…

> you need to use EIBs for your database servers "EIBs"? I would point out that global replication is one of the things that makes CouchDB's master-master replication so tasty. You can't accomplish the same thing with Mongo in a R/W environment since you can only write to the master in a replica set. You could have multiple read-only slaves in other geographical locations, but that isn't always helpful. You can also…

Doh. EIP. Elastic IPs.

Damn, shykes you are exactly right it was just an edge location and Route53 node, not an EC2 region.

Sorry about that guys.

Ah, got it!

This is one of the biggest failings of SimpleDB that I think keeps it held back from being a huge success, the region dependency of it and the seeming lack of support from Amazon (the only product whose forums frequently go a week without a reply).

Had SimpleDB has an optional global redundancy for quick read/writes in all locations, I think it would have been the killer product a lot of people were looking for.

Instead I have to roll my own with a fully connected CouchDB graph of servers. Ahh well.
