Generally Available: LocalDNS for AKS

LocalDNS for AKS is now generally available.  

Large-scale Kubernetes clusters often face DNS resolution delays and reliability issues, especially during upstream outages or high query volumes. To address this, Azure Kubernetes Service (AKS) now offers LocalDNS, a feature that is generally available. 

LocalDNS deploys a DNS proxy on each node, enabling faster and more reliable DNS resolution by handling queries locally. This eliminates bottlenecks, reduces latency, and ensures continued resolution even during upstream DNS outages through configurable serve-stale settings. 

With no application-level changes required, LocalDNS delivers immediate performance improvements and supports advanced DNS customization for both internal and external domains.
