MuleSoft Runtime engine (Mule) is a lightweight integration engine that runs Mule applications and supports domains and policies. Mule applications, domains, and policies share an XML DSL (domain-specific language).

  • Extended Support versions are only available on CloudHub for applications already deployed on it.
