I meant running multiple VMs in VirtualBox to simulate a distributed system as an alternative to buying multiple Raspberry Pis, not running Linux in VirtualBox.

The really cool thing, though, about multiple Raspberry Pis is that the systems really are running in parallel, rather than faking it with multitasking. That's definitely worth something in an educational context.
- Sir_Cmpwn 9y agoAh, I see what you mean. That makes more sense. Still, I think there's value in having this cool looking machine to fiddle with over the computer they're used to messing with all the time. I think it likely to engage more.
- amelius 9y ago> I think it likely to engage more. As opposed to running it by yourself on your own computer in a bunch of virtual machines?
- Sir_Cmpwn 9y agoAbsolutely. Do you see no value in the maker skills involved in building the rig?
- Const-me 9y agoThis. Technically, a single PC with multi-process program is often enough. I've used this approach when I worked on some cloud game server, worked good, I just needed to make sure service discovery was OK finding multiple server instances on same IP but different ports.

Imho, multitasking is a much cooler feat than parallelism by mere duplication of the CPU. It requires much more engineering effort, e.g. in areas of memory coherence and such. Also, a modern desktop CPU will be an order of magnitude faster than the RPi, so you'll need a lot of them to match performance.
