Dig Smart - Building a Reliable Cloud Native DNS for Modern Networks

Learn how to operate and automate a highly available, geo-redundant DNS service for modern 5G mobile networks using cloud-native technologies in this 37-minute conference talk from the Linux Foundation. Explore Swisscom's multi-cluster architecture that leverages ExternalDNS, PowerDNS, and CoreDNS to deliver reliable DNS services at scale. Discover how the system maintains resilience when clusters fail and examine monitoring and troubleshooting strategies for multi-cluster DNS deployments. Gain insights into handling demanding DNS requirements including rare resource records like NAPTR, and understand how to build DNS services with cloud-native tools when compliance, governance, or availability concerns prevent the use of public DNS-as-a-service offerings. This presentation is particularly valuable for engineers and architects working with telecommunications infrastructure, 5G networks, or any environment requiring enterprise-grade DNS reliability and performance.
