All hardware breaks, occasionally. In the case of a server - it’s usually the storage which fails eventually, be it SD cards, eMMC, an SSD, or a rotating disk (remember those?).
The new server setup at JeeLabs relies completely on a single Odroid XU4 in a CloudShell.
What if it breaks, gets hacked, stolen, or otherwise ceases to work?
Here’s the backup plan: we set up a second server, with fairly modest hardware, and we keep it around for when things turn sour.
