 I have always wanted a highly available setup for my personal websites. I could have used off-the-shelf hosting solutions or hosted my sites in an AWS S3 bucket. I have used technologies like BGP, LVS/IPVS, ldirectord, Pacemaker, heartbeat, heartbeat2, Corosync, keepalived, DRBD, and commercial F5 Load Balancers for high availability at work. 

 

-But still, my personal sites were never highly available. All those technologies are great for professional use, but I was looking for something much more straightforward for my personal space—something as KISS (keep it simple and stupid) as possible.

 It would be fine if my personal website wasn't highly available, but the geek in me wants it anyway.

My auto-failover requirements


 

 
    
 
  • Be OpenBSD-based (I prefer OpenBSD because of the cleanliness and good documentation) and rely on as few external packages as possible. 
    • 
-
  • Don't rely on the hottest and newest tech (don't want to migrate everything to a new and fancier technology next month).
    • 
+
  • Don't rely on the hottest and newest tech (don't want to migrate everything to a new and fancier technology next month already).
    • 
 
  • It should be reasonably cheap. I want to avoid paying a premium for floating IPs or fancy Elastic Load Balancers.
    • 
 
  • It should be geo-redundant. 
    • 
 
  • It's fine if my sites aren't reachable for five or ten minutes every other month. Due to their static nature, I don't care if there's a split-brain scenario where some requests reach one server and other requests reach another server.
