In this presentation, created for a webinar recorded on 4/26/2012, we demo'd Amazon Route 53's new Latency Based Routing (LBR) feature. LBR is one of Amazon Route 53’s most requested features and helps improve your application’s performance for a global audience. LBR works by routing your customers to the AWS endpoint (e.g. EC2 instances, Elastic IPs or ELBs) that provides the fastest experience based on actual performance measurements of the different AWS regions where your application is running.
