I've been saying this for years. When the last Raspberry Pi shortage happened people were scrambling to get them for building these toy clusters and it's such a shame. The Pi was made for paedogogy but I feel like most of them are wasted.

I run a K8s "cluster" on a single xcp-ng instance, but you don't even really have to go that far. Docker Machine could easily spin up docker hosts with a single command, but I see that project is dead now. Docker Swarm I think still lets you scale up/down services, no hypervisor required.

You're describing people using RPis to learn distributed systems, and you conclude that these RPis are wasted because RPis were made for paedogogy?

That's perfectly fine. You do what works for you, just like everyone else. How would you handle someone else accusing your computer resourcss of being wasted?

I’ve learned so much setting up a pi cluster. There is something so cool about seeing code run across different pieces of hardware.

The point was you don't need to wait for 8 Pis to become available when most people can get going straight away with what they already have.

If you want to learn physical networking or really need to "see" things happening on physically separate machines just get a free old PC from gumtree or something.

You also don't need RPis to learn anything about programming, networking, electronics, etc.

But people do it anyways.

I really don't see what point anyone thinks they are making regarding pedogogy. RPis are synonymous with tinkering, regardless of how you cut it. Distributed systems too.

		I think you misread my comment, maybe it's clearer if I say "(admittedly) the pi is meant for paedogogy (however) I feel like most of them are wasted".
