Most of the best Raspberry Pi projects have at least one, but there are 83. It was initially planned to pack 100 Raspberry Pis. However, the bandwidth cost had very much to make for a simple operation. The cluster is started at the Raspberry Pi 3B, but it also has a single Raspberry Pi Zero 2 W feature. Each Pi is equipped with a heatsink to keep the operation cool. There are two uninterruptible power supplies and two ProSafe switches that connect all the Pis. Many Pi clusters tend to run Kubernetes, but Skynet Network explains that each of these clusters has its own VPN with a unique IP address. Around 55 Raspberry Pis are wirelessly connected to the network, but 25 are hard-wired to the switches. The demo video shared with YouTube by Skynet Network shows how to get a closer look at that cluster and see it in action.
