My app allows for "share nothing" architecture, basically using multiple DNS A records as load balancing. Currently it has 6 servers.

Even if 5 of them would go down at the same time, the site would still work as intended (thought probably couldn't handle peak load with less than 3 or 4). If one of or two are down, nothing happens.

Also completely reinstalling a server takes around an hour.

Yes, but comment I was replying to mentioned a 48 euro budget, it is a price of a single server.
