Mule is the runtime engine of Anypoint Platform that combines data and application integration across legacy systems, SaaS applications, and APIs. It can deploy anywhere as an on-premises integration engine, hybrid iPaaS, or API gateway. Mule integrates events in real-time using its staged-event driven architecture and can also move millions of records between applications or data sources in batch. It provides universal connectivity through pre-built connectors or building custom connectors.
