What's the actual use case for rpi clusters like this? If the goal is to learn docker or k8s using a realistic setup involving multiple machines, can't it be achieved by using multiple VMs on one physical desktop instead of using the cluster? The 7-node cluster has only 7GB RAM in total, which is not too much to ask on a desktop.
I don't know what people do with rpi clusters and I'm honestly puzzled why people bother building them. If you get a beefy expensive server, I can understand -- you care about performance. If you get a single rpi to serve files & media in a home LAN it makes sense too -- low footprint, low power and low cost. But I don't know what a rpi cluster excels at. Is it just a toy? Or a learning tool to make computer science & networking concepts concrete and tangible? Or just to get a computer system on a shoestring budget, much cheaper than even a single desktop or laptop?
BTW, computer hardware in Singapore is overpriced. $140 for a switch in Singapore vs $73 for a similarly-capable switch on Amazon. https://www.amazon.com/TP-Link-Ethernet-Unmanaged-Rackmount-...
