Join us for a tech talk where we'll demonstrate how we operate and automate a highly available, geo-redundant DNS service for Swisscom's 5G mobile network using a cloud-native tech stack. We'll provide an in-depth look into our multi-cluster architecture that leverages ExternalDNS, PowerDNS, and CoreDNS. Additionally, we'll showcase how the system behaves when a cluster breaks down, and how we monitor and troubleshoot this multi-cluster setup at scale.

This talk will be particularly interesting for those with demanding DNS requirements—such as applications which require rare DNS resource records like NAPTR—as well as engineers and architects tasked with building a DNS service using cloud-native tools who, due to compliance, governance, or availability concerns, cannot use publicly available DNS-as-a-service offerings.
