WPPs are typically companies with one or more data-center facilities that are connected to the Internet. Web hosting provided by WPPs can vary widely with respect to service quality and cost. Some providers consist simply of a room in the basement of a house and a tier-1 (T1) line connected to the local ISP. Others, however, are corporations with state-of-the-art hosting centers consisting of redundant fiber paths for high-speed Internet connections, redundant electrical power sources, a dry pipe–fire suppression system, and an experienced operations group, available 24 hours a day, seven days a week.
Web hosting can be provided on a shared computer environment or on a dedicated computer system. When a Web site consists only of standard HTML code and receives a small number of visitors, shared hosting service is the best solution. When a Web site consists of complex common gateway interface (CGI) scripts and proprietary programs and receives a large number of visitors, dedicated hosting service is the best solution.
