DESCRIPTION
Learn how to utilize Amazon Route 53 latency-based routing, weighted round-robin, and other features in conjunction with DNS failover to direct traffic to the least latent, most available endpoints across a global infrastructure. We explore topics such as balancing traffic between endpoints in terms of load and latency, and discuss how to provide multi-record answers to improve client-side resiliency. As part of this session, Loggly will present how they utilize Route 53 for their traffic management needs.
