Dedicated server hosting :- Load balancing
There are a number of web hosting Dedicated servers available to host your web site. You have to choose the web hosting type according to the requests made and the status of your site or in other words the popularity of your site.If your site is gaining popularity then naturally the requests made for your site increases and you have to change your Dedicated server type so that the time required for the web pages of your site to be displayed after the request is made is less.If you have a dedicated server and then to it is not responding quickly to all the HTTP requests due to the high amount of requests made at the same time then you have to find some way so that it responds quickly to all the HTTP requests made.So the option is to upgrade the configuration of your server but as upgrading your server is very expensive it will no more be a cost effective and for this you have to find a cost effective solution.
To solve this problem you have to improve the Dedicated server scalability.The respond time of the server being slow is due to the number of HTTP requests made at the same time for the site hosted on a particular server is much more than the server capacity to respond to the requests.For this reason there are many Dedicated servers needed so that the load which is on a particular server gets distributed among a number of servers and there is an increase in the scalability.This process of distributing the load so as to increase the scalability is called clustering.The load distribution among the servers is called as load balancing.Load balancing is applied to both database as well as application servers.
Load balancing mechanism :-
The HTTP requests made are to be evenly distributed when there are multiple servers in the group.IP Spraying is the load balancing mechanism which is used for distributing the HTTP requests among the servers.It acts like a single server to the clients as an internet browser.The equipments used for Ip spraying which can even be called as “Load balancers” are “Load dispatcher” and “network dispatcher”.HTTP requests are redirected to a server in the server cluster by the IP Sprayer.Type of IP sprayer is very important as all this depends on it so that more scalability and load balancing is provided by the architecture so that it can overcome all the fail-over requirements.
To get a rough idea of the structure of the load balanced server you can have a look at one of the load balanced server.
