To use Edge Resolver, you must first specify the configuration information for the DNS data that you would like to discover. You can create discovery configurations to discover DNS data from Address Manager configurations, AWS, Azure, or GCP cloud environments.
Once you have created the discovery configuration, an associated discovered domain list is automatically created. The discovered domain list are used as a Match List for discovered namespaces, and contain the domains for which the DNS resources will be used. The discovered DNS resources are contained by a snapshot uploaded to Edge Cloud by discovery instance, and downloaded by DRS and used by Edge Resolver.
