Spring Boot ships with the `BufferingApplicationStartup` variant; this implementation is meant for buffering the startup steps and draining them into an external metrics system.
Applications can ask for the bean of type `BufferingApplicationStartup` in any component.
Additionally, Spring Boot Actuator will <<production-ready-features.adoc#production-ready-endpoints, expose a `startup` endpoint to expose this information as a JSON document>>.
