I'm a technical evangelist at Combell, the leading Belgian webhoster. My mission is to bridge the gap between code and infrastructure. I convey my message through various media: I speak at conferences, I write blog posts, I record vlogs, I write books, and I love interacting with people.
As an international conference speaker, I've presented 207 talks in 15 countries.
I'm the author of "Getting Started with Varnish cache", an O'Reilly book about Varnish.
Getting Started with Varnish Cache
Varnish is a so-called reverse caching proxy that acts as an intermediary between the browser and the webserver. Varnish stores HTTP responses and serves them to the browser, without accessing the backend for every request. This causes a massive speed increase.
My book explains how you can get the most out of the software, by tuning either your Varnish configuration, or by optimizing your web application.
