Virtual and augmented reality in training: when traditional hosting isn't enough
Virtual and augmented reality have stopped being futuristic experiments and are already appearing, pragmatically, in technical training and procedure simulations — fields like healthcare, engineering and workplace safety lead this adoption, using immersive simulations to train for situations too expensive or dangerous to practice in the real world. Integrating this kind of content into Moodle is technically possible, but it requires facing limits that traditional Moodle hosting wasn't designed to solve.
VR/AR files are a different size category
A traditional class video might be a few hundred megabytes. An interactive virtual reality environment, with textured 3D models, easily exceeds gigabytes per experience. This completely changes the storage math — the same institution that ran comfortably on 50 GB of moodledata may need a plan with hundreds of gigabytes just to accommodate a handful of simulations.
Streaming, not just storage
It's not enough to store the file — it also needs to be delivered smoothly to the student's device, often a VR headset or tablet with limited local processing power. This requires a data streaming capacity that hosting sized for "serving HTML pages and recorded videos" simply doesn't have as a design assumption.
Usually the right answer is a specialized service, not Moodle alone
In practice, the most common and technically stable approach is for Moodle to function as the organizational "hub" — enrollment, progress tracking, certification — while heavy VR/AR content stays hosted on a platform specialized in that media type, integrated with Moodle via link or plugin, instead of trying to make Moodle itself host and deliver the heavy files directly.
Questions before investing in VR/AR integrated with Moodle
- Does the current hosting plan support the storage jump VR/AR files require, or would a significant upgrade be needed?
- Does it make more sense to host immersive content on a specialized service and just link to it from Moodle?
- Do students' devices (VR headsets, tablets) have processing capacity compatible with the planned content?
Promising technology that calls for separate planning
VR/AR in training is a real trend with valuable applications, especially in technical fields. But it's also one of the few situations where the right answer might not be "upgrade the Moodle hosting plan" but rather "use the right tool for each type of content."
