Since a site requires both hosting space and a domain name, it’s important to be able to seamlessly manage not only the former, but also the latter. Even if the web hosting service is fast and reliable, registering a brand new domain name and pointing it to a website may be a torture and may require a lot of time and effort. In fact, that’s the situation with the great majority of hosting providers out there – you’ll have at least two accounts, one hosting account and one billing account, and registering a domain and getting it online will involve switching between the two accounts. It’d be way more convenient if you could do all these things from one and the same place and focus on your site, not on different system tasks.
