This is the story of the journey followed by LesFurets.com, the leading French insurance aggregator, to transition from one release per month to a release per day.

In this talk, you will learn how we first started by improving the monitoring tools and tests suites, automated everything and built tools to remove QA testing.

Finally, we will see why having a continuous delivery process deeply impacted the organization and how we pushed code into production.
