Web hosting is a service which allows websites to be published to the internet and hosted so they are accessible on the around the world on the World Wide Web for everybody to find. Web hosting companies buy or lease many servers in a data center which are connected to the internet, and sell partitioned space on the server, typically called Shared web hosting. This allows website owners to pay a small monthly fee for the hosting space as the cost is spread across many other websites hosted on the same server.
Until 1991, the Internet was restricted to use only ...for research and education in the sciences and engineering... and was used for email, telnet, FTP and USENET traffic - but only a tiny number of web pages. The World Wide Web protocols had only just been written and not until the end of 1993 would there be a graphical web browser for Mac or Windows computers. Even after there was some opening up of internet access, the situation was confused until 1995.
For example, you may certainly contact your host at any time, but when are they available to respond to your questions and concerns? How long will it take for someone to get back to you? Will there be someone to help you if your mission-critical website goes down at 3:00 in the morning? What language(s) do your host providers speak?

This is a new type of hosting platform that allows customers powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. A cloud hosted website may be more reliable than alternatives since other computers in the cloud can compensate when a single piece of hardware goes down. Also, local power disruptions or even natural disasters are less problematic for cloud hosted sites, as cloud hosting is decentralized. Cloud hosting also allows providers to charge users only for resources consumed by the user, rather than a flat fee for the amount the user expects they will use, or a fixed cost upfront hardware investment. Alternatively, the lack of centralization may give users less control on where their data is located which could be a problem for users with data security or privacy concerns.
