Automation
Reduces the need for manual interventions when creating or modifying DNS records by automatically updating entries based on changes in the state of services in Kubernetes.
Scalability
As new applications or services are deployed, External-DNS can easily manage the addition of new DNS records, making it a scalable solution for dynamic environments.
Consistency
Ensures that DNS records are always up to date and consistent with the current state of services, minimizing the possibility of human error.
Integration with Cloud Providers
Supports multiple DNS providers (such as AWS Route 53, Google Cloud DNS, Azure DNS, among others), allowing companies to utilize their existing infrastructure.
Resilience
With automation and continuous updating, services become more resilient to failures as DNS records are quickly adapted in case of changes to pods or services.
Improved User Experience
With stable and accessible DNS addresses, end users have a more fluid and reliable experience when accessing applications.
