MuleSoft is a lightweight Java-based integration platform that allows developers to connect applications together through various protocols like JMS, web services, HTTP. It acts as an enterprise service bus facilitating communication between different applications regardless of their underlying technologies. Key capabilities include service creation and hosting, mediating communication through message routing and transformation between different data formats. The core components that enable this include endpoints, scopes, transformations and filters. MuleSoft applications can be deployed on-premise or on CloudHub and managed through Mule Management Console.
