Web hosting service
A web hosting service is a type of Internet hosting service that allows
individuals and organizations to make their website accessible via the
World Wide Web. Web hosts are companies that provide space on a server
owned or leased for use by clients, as well as providing Internet
connectivity, typically in a data center. Web hosts can also provide
data center space and connectivity to the Internet for other servers
located in their data center, called colocation, also known as Housing
in Latin America or France.
The scope of web hosting services varies greatly. The most basic is web
page and small-scale file hosting, where files can be uploaded via File
Transfer Protocol (FTP) or a Web interface. The files are usually
delivered to the Web "as is" or with minimal processing. Many Internet
service providers (ISPs) offer this service free to subscribers.
Individuals and organizations may also obtain Web page hosting from
alternative service providers. Personal web site hosting is typically
free, advertisement-sponsored, or inexpensive. Business web site hosting
often has a higher expense depending upon the size and type of the
site.
Single page hosting is generally sufficient for personal web pages. A
complex site calls for a more comprehensive package that provides
database support and application development platforms (e.g. ASP.NET,
ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities
allow customers to write or install scripts for applications like
forums and content management. Also, Secure Sockets Layer (SSL) is
typically used for websites that wish to keep the data transmitted more
secure.
The host may also provide an interface or control panel for managing the
Web server and installing scripts, as well as other modules and service
applications like e-mail. A web server that does not use a control
panel for managing the hosting account, is often referred to as a
"headless" server. Some hosts specialize in certain software or services
(e.g. e-commerce, blogs, etc.).
