What is the application server included with WebMethods?

I’m struggling to understand what WebMethods does, coming from a dev background familiar with DevOps and continuous integration tools like Jenkins/Hudson. My question is, what, if any, J2EE server is included in WebMethods? Is it its own application server? Do you point it to one?

Thanks,
Tony
