We were thinking about redundancy options for CCIE.PL today. There are few restrictions we have there, both came either from policy or our personal thoughts about several aspects of paid services and sharing admin access. But simply we are thinking how to automate failover in case our primary server or database have problems. Easiest solution would be to use Cloudflare free tier service but let’s say we don’t want to do this now. So we were looking on the other options and there was an idea that maybe we can use cloud load-balancer for on-premise services. First thought – it’s brilliant. On second thought – definitely that idea was wrong. Let me show you why.
