DNS performance issues can cripple production Kubernetes clusters, causing application timeouts and service outages. LocalDNS in AKS solves this by moving DNS resolution directly to each node, delivering 10x faster queries and improved reliability. In this post, we share the results from our internal tests showing exactly how much of an improvement LocalDNS can make and how it can benefit your cluster.
