Why Are Web Servers Important?

By Josh Hart


Almost everyone has actually become aware of internet servers but a lot of individuals don't actually understand exactly what they are! In a certain sense a spider is an internet server however that is not the kind of internet server we have in mind. This post clarifies in easy terms exactly what a net web server is and also explains why they are so important for the reliable performance of modern-day internet sites. The most usual type in use today is most likely Apache. It is a software application but it operates on a physical equipment device (or server). So when someone mentions an internet server they typically mean both the hardware device and the software that is operating on it. Lets look at how these servers normally work:

\* initially you enter the address of a websites in your browser, say Amazon or eBay

\* your browser delivers a page request to the web server at the address you offered (its like a street address)

\* the Amazon or eBay server intercepts your page request

\* if the the server does certainly have the web page you asked for then it will return the web page to your browser

\* you see the page that you requested appear in your browser as if by magic: -)

The above summary is a streamlined view of an internet server however it does the job of clarifying just how they work. However lets look at a much more complicated situation. This is when the server sits in front of numerous other servers. The reason for this is that if a website receives lots of traffic (I want) then if only one server is utilized it will quickly get overworked and grind tro a halt. This results in fantastic gnashing of teeth and stress as we switch our attention to an alternative internet site to discover what we were trying to find. However if there are lots of servers who can answer our request it is unlikely that any type of one server will certainly get exhausted. The secret is to make sure that the requests are shared amongst the offered servers. This is were our web server comes to the rescue once more. One solitary server sitting in front of the other servers (or back-end servers) can easily intercept our page requests and instead of trying to do all the work itself it shares the requests with the other servers who as an alternative do all the work involved in returning the requested page (this is called load balancing). This in turn results in pleased web surfers as we usually get a fast feedback to our web page request.

So from the above you can see that web servers are an important part of the modern-day internet especially when they are load well balanced and offer us with quick feedbacks to our inquiries and page requests.
