Step 5: Enable dependency discovery (optional)

Dependency discovery automatically identifies the AWS services, internal endpoints, and third-party endpoints that your service calls. It uses DNS query log analysis with a 35-day look-back window and continuous polling to identify dependencies you may not know about, including unexpected cross-Region calls or critical third-party dependencies.

Dependency discovery is an optional add-on. To enable it, navigate to your service in the console and choose Enable dependency discovery. Once enabled, the next generation of Resilience Hub begins discovering dependencies and surfaces them on the Dependencies tab of your service.
