Web hosting allows businesses, organizations, and individuals to make their websites or apps visible on the internet. Whether they're using a dedicated server, or sharing resources, every website is hosted on a server. The only way for a website to be visible on the internet is if it's hosted by a web hosting service provider, also known as a web host. In order to find a website, you type the domain name (or URL) into your browser. Your computer will then connect to the server where the website is hosted, and the webpage is delivered onto your screen.
If you're not sure of the type of hosting your business needs, you might want to start small, with shared Web hosting. You can always graduate to a more robust, feature-rich package of, say, VPS hosting or even dedicated hosting in the future. Unfortunately, some hosts don't offer all hosting types. Consider how much you expect to grow your website, and how soon, before you commit to anything longer than a one-year plan. It's worth spending the time up front to make sure that the host you select with is able to provide the growth you envision for your site, as switching web hosting providers midstream is not a trivial undertaking.
The user gets his or her own Web server but is not allowed full control over it (user is denied root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client.
