 As part of provisioning, the APM Server and Fleet Server are already configured to work with Elasticsearch and Kibana. At the end of provisioning, you are shown the secret token to configure communication between the APM Server and the backend [APM Agents](https://www.elastic.co/guide/en/apm/agent/index.html). The APM Agents get deployed within your services and applications.
