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.

An internal CA is used to provide and validate client certificates for the gRPC connection to Jaeger. The CA is distinct from other internal CAs (for example, ZooKeeper) for security purposes.
