Hi all, I wondering if there is any wisdom out there on whether the following might be possible / undesirable. I have a fairly large (30Megs) Scorm zip file (version 1.2) that I am developing that learners will download from my Moodle LMS. I'm a bit concerned about a classroom type environment where multiple learners will start the Course at the same time and start downloading the file concurrently. I have external rtmp links to Streaming Video from CloudFront CDN and am happy enough with the tradeoff of a small pause while buffering so as I don't have the size of that video content added to the payload the learner needs to download. So I also have a bunch of ScreenCasts in my Scorm file that I would also like to externalize preferably to the CDN. I am using Adobe Captivate and know that I can "Externalize Resources" of SWFs but I am wondering is there any way to externalize them to a Cloudfront URL instead of a having them reside within the same folder on the filesystem (where they will end up in the same big zip file with the other Scorm files). Any insights would be appreciated, thanks,
Fergal

Servers are designed to handle this sort of situation. I'd be more interested in your bandwidth than whether or not the server can handle the load. Your risk of bandwidth issues is the same, if not a little higher, if you start splitting out your assets.

I'm almost always in favor of externalizing assets. It makes the initial download quicker (don't need to download *everything* before starting), and also helps cache frequently used items, such as images, CSS and JavaScript files.
Regarding video , most LMSs I've used are horrible at serving video files. Using a reliable CDN that specializes in video -- especially streaming video -- is a great idea.

Video Streaming is definitely an issue especially when relates to
videos inside scorm packages. At EduBrite we addressed this issue
(although not a solution for situations, where scorm is must have
requirement) by providing course creation and delivery in our
proprietory way in our platform which utilizes video streaming
delivery (RTMP) for any video included in the course. It becomes
difficult to provide this with SCORM packages because the video widget
included in the packages have to be coded to utilize rtmp instead of
referring video over http. On related note - Live streaming over http/
HTML5 Video tag is an encouraging draft spec but at present the
browser's support is limited.

We do a bunch of technical "New Model" automotive courses & the data is
very last minute and changing. We make our life easier by delivery
content on video clips - SCORM (an old Docent LMS) - Been doing for 3
years & no problems. External files, FLVs, straight progressive
download, but compressed at 10 fps & a few other settings. We also allow
users to choose a 1fps version if bandwidth is challenged, but it rarely
used. Content usually can be updated by replacing external clips. The
player is Flash driven.

At my last company we were video heavy and used a streaming server,
but around 2005 dropped it in favor of the much simpler approach of
external flvs. Once they got the settings right we never looked back.
