Starting web hosting
The whole concept of web hosting is quite interesting.
When you visit a website a web page is shown. This web page is
downloaded from the server where web site is hosted to your web browser.
A website contains many web pages which are made up of graphic images
and texts. These web pages are stored on the server and are downloaded
to web browser when somebody needs to view them.
So if you intend to host a website then first
thing which you must have is a web host who will be providing you the
web space over the server for your website. The host proving this
hosting facility is called web hosting company or provider. Once your
website is on the server then the users can access it through internet
and requested pages will be downloaded to his browser on clicking on the
links.
A well established host can provide hosting
facility to a number of websites. 'Hostgator', a well known hosting
provider hosts more than 4 lakh websites on its servers. For this it
requires many web servers for hosting these websites. After this these
servers are connected to the internet. These servers are kept in a
physical 'data centers'. Since these data centers are needed to be
functional all the time so these data centers are made fully secure with
24X7 power-backup. Proper arrangements are there to protect these from
fire. These have virus detection programs and temperature control
systems with proper data back-up facility. Arrangements for disaster
recovery are also needed for these data canters in case of any major
disaster.
Now as far a web hosting is concerned, it can be
of many types- shared hosting, dedicated hosting, co-location hosting
and reseller hosting. In shared hosting there are several websites which
share a common space on the server. Since a server can host numerous
websites people think that the performance of the server deteriorates
with the increase in number of websites that are being hosted on the
server, but this is totally wrong as servers are equipped with high end
components to cater to such loads.
In case of dedicated hosting, a customer is
provided with a specific server. Since the server is dedicated to one
customer only, he can host as many websites as he wants on that server.
In case of dedicated hosting the customer has the option of changing
software configuration and he can handle large site traffic. The charges
for dedicated hosting quite high and can range from $50 to $500 per
month depending upon the facilities provided by the company. In case on
co-location hosting, the customer can also own the hardware of the web
server with all the facilities of dedicated hosting. It provides more
flexibility to the customer in terms of maintenance and control.
In reseller hosting a web space is offered to a
party at some discounted price by the provider and this party can resell
this space to some other customer in order to make profit.
