Using high performance caching is an excellent way to speed up most websites, and the closer to the end user you can put the cache, the more efficient it is. But often problems show up with fast updates (such as price changes in a webshop). By integrating an external close-to-user cache (in this case Varnish) with the backend systems (in this example, Django+PostgreSQL), we can can get best of both worlds - long cache time, and fast invalidation.
