This week's episode is about load balancing, which is a concept where traffic load gets distributed to a collection of underlying servers using an algorithm to ensure equal distribution.

Varnish is a powerhouse, and a lot of the use cases you'll see about it are about delivering stellar performance, specially in CDN contexts.

This should give you some ideas on how to use it more, notably back within the confines of your infrastructure.
