Hi, About the 5 backends limit, you might be interested by this link: https://www.varnish-cache.org/docs/trunk/phk/backends.html
PHK basically states that 1000 backends is not an unreasonable number. I assume that backends are limited according to available resources and other factors that can't be established without proper measurements.
