Change region in an app between AWS-China and AWS-Global

Question

AWS noob here.

Apparently cross region replication is impossible with AWS-china.

I'm thinking about an android app that could change the AWS region they're using based on their location.

For example: If i'm in USA my app would be connected to global-aws. When I travel to China my app gives me a dialog to connect to the aws-china. Since data replication is impossible the app would recommend the me to create my account(duplicate the account if possible) on the Chinese server and use the app within China. Once outside of China app returns to global-aws and works normally.

Is this scenario possible with a single app that can work seamlessly cross region?

Or am I better off start working on my Chinese specific version of the app? If so how do I deal when a global-aws user visits China and wants to connect with Chinese users?

Answer 1

Data into/out of China is a complex topic, as are VPNs and direct connects, plus licensing for all this.

From your description seems you just want GEO-DNS so in China you connect to a Chinese AWS server, which is easy enough, if you have the server/license.
