Having a site is more complex than simply having a domain name and uploading files for it on a server. The hosting service also includes things such as domain records, databases, email addresses, statistics, FTP access, etc. Although they probably are not the first thing which comes to mind when you refer to the word “website”, they are an integral part of any site and none of them can be skipped. If you wish to start and sustain a profitable web presence, you need a simple way to control these things, specifically if you aren't very experienced. In addition to the ease of use, it is also important to have total control over your domains and the hosting service associated with them.
