This talk will concentrate on the various strategies you can use to ensure that developing and releasing new features to a live website is stress-free. Firstly we will look at how organising your source code into branches can provide confidence and allow for features to go-live in any order. We will the consider the mechanics of deploying a new version of the website to the server, ensuring that we can repeat the process the same way every time. Finally we will look at how to roll back a deployment easily and quickly when something goes wrong.
The slides are over on Rob's site if you want to follow along with the talk.
