Mule Standalone Server is a proprietary application server that can host Java code, web services, and Mule applications. To deploy a Mule application, it must be exported from Anypoint Studio as a zip file and copied to the Mule Standalone app folder. Starting the mule.bat file launches the Mule Standalone server, deploying any applications in the app folder. The document then walks through creating a simple Mule application in Anypoint Studio, exporting and deploying it to the Mule Standalone server, and invoking it to confirm it is running successfully.
