Maximizing Failover Efficiency


As the industry iterates beyond simple cloud deployments, application & identity architects confront new challenges in deploying and managing complex application instances which span the globe across multiple provider regions. Rapid failover from one region to another is a critical component for these distributed applications- but did you know how much your cloud DNS service and DNS architecture impact the speed that traffic can be rerouted from one region to another? In this talk, Jon Lehtinen shares his experiences testing several DNS architectures, and highlights how different resolution methods, failover policies, and other seemingly inconsequential components greatly impact how instantaneous- or not- your failover can be. (User Experience, Architecture, Deployment & DevOps, Jon Lehtinen).
