How to direct traffic to different servers per geographic location?

If I have servers placed across the globe through AWS, Rackspace, some other cloud, or even bare metal, how do I direct traffic from, say Singapore, to a server instance living in the Asia region? Is it some kind of load balancing, or DNS type things I would have to configure? Thanks!
