Overview

Apache is configured as a reverse proxy and there is an internal Badger database stored at /var/jaeger/badger.

Zuul sends telemetry information to Jaeger via the gRPC protocol.

The internal CA (zk-ca) used to create ZooKeeper certs for Zuul is used to provide and validate client certificates for the gRPC connection to Jaeger as well.
