To serve up web pages, a web site requires a hosting computer and server
software which runs thereon. This computer provides storage space
for the web site's pages and its software, while the web server software
manages the HTTP communication protocols between the server and client
software (such as a browser). Most web hosting services also provide
FTP server capabilities, enabling files to be transferred between server
and client computers.
This blue and gray illustration depicts server computers that could host multiple web sites, with each web site running on its own virtual server.
Virtual web hosting, sometimes called shared web hosting, is the most
common and economical type of hosting plan. Virtual hosting, the
process of running multiple "virtual" servers on a single host computer,
enables one computer to host hundreds of independent web sites. Web
sites literally share resources, applications, and an operating system
environment with many other web sites on the same server computer.
This type of web hosting is popular among commercial web hosting service
providers, who appreciate the manageability and efficiency of virtual web
hosting. Many virtual web hosting applications use virtual DNS
resolution, which associates each domain name with its corresponding
virtual web server. Virtual DNS resolution is compatible with both
name-based and IP-based virtual hosting techniques. But there are
drawbacks to this type of hosting. With this hosting configuration,
compromises to a single web site can affect the performance and security
of other sites on the server.

Another type of virtual web hosting uses VPS or Virtual Private Server
technology, in which a web server computer is divided into multiple
isolated environments. Each web site runs in its own environment
with its own server software. As with a dedicated server, each VPS
has its own independent operating system with its own web server, mail
server, and independent software instances. VPS offers a greater
degree of control than basic virtual hosting, and often features multiple
domain name support.
