INTRODUCTION TO WEB HOSTING
Web
hosting is a service that allows users to post Web pages
to the Internet. A Web host, or hosting service provider
(HSP), is a business that provides the technologies and
services needed for Web sites to be viewed on the Web.
Web hosting is a primary service that consumers can utilize
after obtaining either dial-up or broadband access to the
Internet. It allows users to disseminate their own information
resources to any Internet user that is interested in accessing
them. Web hosting utilizes the server/client model to distribute
content. A Web hosting provider will offer its clients access
to a Web server that will push that client's content to
recipients on request. Recipients use clients, or Web browsers,
such as Microsoft Internet Explorer or Netscape Navigator
to request content from the Web over their own Internet
connection.
Web
sites are hosted, or stored, on a special computer called
a server. The server, or host computer, allows Internet
users connected anywhere to reach your site when they put
in your domain address, for example: www.yourcompany.com.
The
host computers are set up so that when someone types in
your domain name (your Web address), the address will follow
a route from computer to computer until it reaches your
host computer and your web site. Then the Internet user
will be able to browse through your Web site. Hosting companies
usually require that you own your own domain name in order
to host with them. If you don't have a domain name, most
hosting companies will help you purchase one.
To
have a Web site on the Internet you first need to have a
Web server. Unfortunately, owning and operating a Web server
can be very costly and requires technical expertise that
most businesses do not possess. This is where "Web
hosts" come in. Web hosts provide the equipment and
other technical resources that are required to provide a
consumer with their own customized Web site. Hosting companies
charge a rental fee for the service of storing your Web
site and allowing Web site visitor traffic flow to through
their computers to get to the information on your site.
Web hosting services are more advantageous because they
are outsourced, meaning that the physical location of the
Web server does not reside at the consumer's premises. Outsourcing
your Web presence effectively transfers the responsibility
for maintaining your Web site infrastructure from yourself
to an organization that is more competent to do so.
Many
individuals and small businesses take advantage of Web hosts
in order to free themselves from pre-occupying their scarce
human and financial resources on Web host issues. Individuals
and companies who outsource their Web presence do so in
order to achieve the following objectives: reduce and control
operating costs; improve their own company focus; gain access
to in-depth expertise; free internal resources for core
competencies; and obtain access to world-class capabilities
to control IT functions which are difficult to manage.
The
best Web hosting services will provide relatively seamless
access to IT functions that will allow you to self-publish
your Web site. It is important to note that "Web hosting"
strictly refers to providing the consumer with the capacity
to upload content to a server for immediate transmission
for those that request it. Web hosting does not include
the authoring of a Web site or the development of database-driven
components or code. It is incumbent upon the consumer of
Web hosting services to develop this material or have it
developed on his or her behalf.
Web
hosting is offered to the consumer in multiple formats based
upon the user's requirements. These requirements are incumbent
upon cost and infrastructure provided.
Web
hosting can be obtained free of cost from content portal
sites such as Yahoo! GeoCities. Such content
sites invite individual users to establish Web sites on
their domain in order to create a critical mass of core
content on their online property. The user does not pay
for service because it is subsidized by banner advertising.
Because such sites do not charge, they offer limited service
depth and quality of service. For example, free services
will not provide customized hosting services where domain
names are personalized (i.e., www.yourdomain.com).
The
"paid" class of Web hosting services however does
provide such services. Paid services are normally offered
by Internet service providers (ISPs) or by hosting service
providers (HSPs). Paid services provide a reliable set of
offerings that ensure domain name personalization, service
depth and high levels of quality of service. The paid class
of Web hosting includes shared, dedicated and managed services.
Shared is the most basic level of hosting. With shared hosting,
numerous Web sites are shared on one server. While an economic
solution, they typically cannot handle large amounts of
storage or traffic.
If
a consumer's needs are more sophisticated, then they might
opt for either dedicated or managed services.
Dedicated
hosting allots a Web site its own server. This is
more flexible than shared hosting, as webmasters typically
have full control over the back end of the server, including
choice of OS.
Managed
hosting, on the other hand is a dedicated server
that is accompanied by a full suite of technical support,
maintenance and monitoring services. This differs from dedicated
Web hosting, where customers are provided with their own
servers but are still responsible for virtually all administrative
and maintenance duties
