Clustered web hosting is one of the newest category in the sector of web hosting. It’s a different type of web hosting which spreads all of its loads to several machines. It shares things in layers. That means all of the components remains under same network but works as individual. So if any server goes down you can keep your website buzzing with help of the others. In other server systems, if your service provider gets down nothing will work of your website. But this is considered as the greatest benefit of clustered web hosting is this type of things will never happen here. All of the loads are divided here. If one falls there are plenty to give you back up.


There is another blessing of clustered web hosting service is its management system of traffic control. In the traditional web servers, most of the time server goes down due to overload of viewers. Sometimes due to a DDoS attack websites face unusual traffic. In a clustered web hosting system there is no chance of these things. Because clustered web hosting provider distributes your load of traffic in numerous servers. So each of the servers gets minimum load of traffic and never goes down.


The cluster web hosting service prevents server errors too. If your entire website fails then in the traditional servers will see the “error: 404”. But in cluster web hosting service there is no chance of server down. When a server reaches to its maximum capacity, the system automatically transfers the additional load to other one.


How to set up clustered web hosting:

A clustered web hosting service can be set up by using Varnish and Nginx. So before setting up you must need to know what are these things?


Varnish: varnish is a caching server which accelerated by HTTP. Generally is being used for optimization of speed. It maintains the traffic and directs the HTTP requests. It maintains the static copy of HTTP requests of a website.


Nginx: it is a backup service of varnish. It is a very light software and performs as a high HTTP server. But it never handles the users directly. It only responds to the requests that are directed by varnish.

Setup methodology:

Now you need to remember that you have to keep a 512 Mb space in our hard drive. You have a c++ compiler and a g++ source code runner.

Nginx installation: as I’ve mentioned before, you need to set up Nginx for the backup service for Varnish. The latest versions of nginx are Nginx1.4.1, PCRE: 8.34 and zlib: 1.2.8

Go to the given links to get this







tar -zxvf nginx-1.4.4.tar.gz


tar -zxvf pcre-8.34.tar.gz


tar -zxvf zlib-1.2.8.tar.gz

installing varnish: varnish is a software which will be youra serviceman for the vsitors. First ypu gonna need a GPG key for is the link

wget apt-key add GPG-key.txtecho “deb precise varnish-3.0” | sudo tee -a /etc/apt/sources.listsudo apt-get updatesudo apt-get install varnish

From these links you will get the details.
