Can anyone recommend a very simple load-balancing setup for a bunch of tiny cloud servers serving a static app?
I'm currently using round-robin DNS for load-distribution as the simplest thing that could possibly work, but it obviously doesn't actually balance load and it doesn't remove dead servers from the pool. What's the next step up that doesn't cost and arm and a leg to implement?
Choose your favorite provider's load balancer service and add all the machines. Configure the health check to listen for a 200 on /. This will leave you with a SPOF at the LB, but you can round-robin DNS between two LBs on different providers if you wanted to.
