Noteworthy nothing there really seems to be raspberry pi specific, as the raspberry pi os is based on debian, the same could be implemented on N number of ordinary x86-64 small desktop PCs for a cheap test environment. You can find older dell 'precision' series workstation systems on ebay with 32GB of RAM for pretty cheap these days, four of which together would be a lot more capable than a raspberry pi 5.
