Should we schedule the Integration when we use Atom feeds? wanted in Real time basis

Summary:

we have a requirement of updating the DFF on Department when its created/updated. we planned to adapt the Atom feed method and use the 'Organization', we could able to capture when its created/updated. However this could be possible only through scheduled integration. we wanted to do in real time as in when department gets created, Atom feed should get fired in the integration and do the rest of the process.

Content (required):

Can someone please confirm if Atom feeds can fire in the integration in real time instead of scheduled time of integration?
