Tbh 5$ was to just show the order of magnitude. Even if it was 50$ per month, its still alot cheaper. And the cluster we are talking here about is a raspberry box with 10 mashines each 2cpu 8gb, running k8s, replicated storage, my own domain and certificate, metalb load balancers, and few other things. Its not as redundant as AWS, but it never broke in few years of constant work. Chances of all of those machines to break at the same time are astronomically low in normal circumstances. If I spread the cost of that setup over two years of reservation, the monthly cost will be a lot less than 50$.
