The website is ready to be delivered, to be installed on the server and published. This can be done through a simple File Transfer Protocol (FTP) or, for more complex websites, it can involve installing certificates, ssh connections, Load Balancers configuration or cloud computing technologies.
The long and the short of it, this step is all about going live and being proud of the final result. Although the reality on the production servers is always different from the development environment, the website will go live in the end.
Now we can truly celebrate... open the bottle of champagne and take on the city.
