Any domain that you want to host on your web server will have a separate entry in Apache configuration file.

Many applications start their web server and database hosted on the same machine. It's simpler, cheaper and easier to manage. However, as our application grows , a setup like this can bring security issues and scalability problems. A common solution is to separate our database from the application: creating a dedicated database server and allowing applications to connect remotely. This setup is more secure, it can provide you a better analysis of the bottlenecks and definitely makes the scalability easier.

It is the preferred method of processing PHP pages with Nginx and is faster than traditional CGI based methods.
