Hi all, we have a fairly large Scorm package (zip contains about 60 Megs consisting of 3 SCOs) that we upload into the Scorm activity on a Course. The content itself is flash but it has streaming video that is being server up from Amazon Cloudfront CDN (Content Delivery Network). It seems to me that having the Scorm package itself on the CDN would make a lot more sense, so that multiple people downloading it at the same time would not affect our Totara Server. Is there any collective wisdom out there on whether this would be possible to accomplish ?

As far as I'm aware, the problem is that SCORM modules use javascript calls to communicate with the server, and browser security blocks cross-domain communication of that kind so the module has to sit on the server it is communicating with.

From the look of this discussion (which isn't quite the same question, but hits on some of the same issues), it may not be so easy to solve. This said, I'm open to suggestions of how this might work, if the content was AICC HACP then it appears with a bit of tweaking it might be possible: http://blog.commlabindia.com/elearning/lectora-courses-compatible-to-lms

This said, I don't know the technicalities of Amazon Cloudfront CDN and if such a solution is possible.

A direction worth looking into might be the Moodle core external tool module. You'll have to have an LTI provider host that SCORM for you. You can set up a moodle with the LTI provider 3rd party module perhaps.

Another option is hosting the SCORM on the scorm cloud:

Thanks guys for these ideas. We did investigate the Scorm Cloud a few years ago but it was a US-Centric Cloud setup at that point (though they may have changed since them). The LTI sounds like an option but I am wondering if there is any other options that might help solve the issue either with Caching on our Server or on the Client-side with some sort of Peer-To-Peer support if we knew we were deploying to a Classroom of users at a set time ?

Any insights or ideas would be appreciated.
