# Main state machine
<a name="main-state-machine"></a>

 The main state machine is the entry point to the backend ingestion and analysis workflows. The main state machine chains the backend ingestion and analysis workflows as sub-state machines: 
+  **Start ingestion state machine (nested)** – Runs the ingestion process using the ingestion state machine when a customer uploads a media file to Media2Cloud on AWS. 
+  **Start analysis state machine (nested)** - Runs the analysis process using the analysis state machine after the ingestion state machine completes the ingestion process.
