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 app folder of the Mule Standalone server. Once the zip file is copied over, the Mule Standalone server can be started using the mule.bat file in the bin folder. When the server starts, it will deploy the Mule application. The application can then be accessed through its exposed URL.
