I'm giggling at the idea you'd need Kubernetes for a mere two servers. We don't run any application with less than two instances for redundancy.

We've just never seen the need for Kubernetes. We're not against it as much as the need to replace our working setup just never arrived. We run EC2 instances with a setup shell script under 50loc. We autoscale up to 40-50 web servers at peak load of a little over 100k concurrent users.

Different strokes for different folks but moreso if it ain't broke, don't fix it
