The big day has finally arrived! By the end of this appendix your site will be live, and only a few minor deployment issues now stand in between you and your online aspirations. Actually that's not quite true! I should make it clear that there's nothing particularly complex about deployment; it's just that you need to keep on top of a lot of different issues. Making silly errors at this stage can have dramatic effects on the final product because we are dealing mainly with configuration issues when we deploy a fully developed application. Of course, making errors is not the end of the world, because we are going to test everything very thoroughly.
