ZAPP deployments are built from two runtime components: ZAPP Listeners and the ZAPP Aggregator. Listener pipelines run near telemetry sources. The ZAPP Aggregator provides central fan-in, listener coordination, and consumer-facing APIs.

Use these pages to understand what each component runs, which configuration fields matter first, and where pipeline configuration fits into a deployment.
