SCORM Dispatch lets you decide where your content is hosted, and it allows you to control distribution of your content. It is available as a hosted solution (via SCORM Cloud) or can be installed on your servers.
Dispatch works by creating a Dispatch Package out of your existing course. A Dispatch Package is a shell of a SCORM package that can be imported into an LMS. When the shell is launched by an LMS, it points back to your content – on your servers (or SCORM Cloud). This gives you a new level of control over your content — a level not available from a traditional LMS alone.
That depends if you want us to store your courses for you (Cloud) or if you want to choose where you want to store your courses (Engine).
