Route53 DNS Failover Webinar

| | Comments

This morning, Amazon Web Services hosted a webinar on using Route 53 DNS failover to provide high-availability solutions. Sean Meckley, Product Manager for Route 53, shared how this feature allows you to build applications that are resilient to failures. We were invited to share how InfoSpace uses Route 53 to enable automatic failover between AWS regions. I shared some details on our multi-region architecture, how we setup latency based routing with health checks, how we tested the service to make sure it worked for our use cases, and our results (we get automatic failover between AWS regions in about 150 seconds).

You can get the slides here and watch the presentation here (we talk about InfoSpace starting around the 25:00 mark).
