Load Balanced Web Servers for Scalable and Distributed Hosting

By | July 27, 2012

What is Load Balancing?

Linux Load Balanced Servers requires a cluster of dedicated servers that can be designed to work together to share the load of a website or application that is the common link between these servers. Often the servers that form a load balancing cluster are of a high specification as websites that receive high volumes of visitors require powerful backbones that are capable of supporting every request that the website receives. Load balancing is applied to web servers more often than not because this is where a majority of requests are made to and in most situations there isn’t anything that can be done to reduce the impact of requests for web pages and scripts, but alterations can be made to database/SQL statements to reduce the number of database queries that are made in a single page request.

A load balancing cluster requires at least two web servers and two database servers so that the loads can be spread evenly; a further server is required to act as the ‘load balancer’, which will route traffic as required to the server with the lowest load at that point in time. The second database server in the cluster won’t be actively accessed, instead with the first database server being the only actively accessed database host and the second server being in place for backup purposes.

Benefits of Load Balancing

Scalability is important when developing a large website because otherwise you could face downtime and for many businesses this can introduce the element of lost revenues, therefore making the investment of a large and stable hosting infrastructure a justifiable necessity. Host.co.in offers a range of different load balancing solutions that you can take advantage of how you wish so that you can provide your website with a suitable platform on which it can be hosted. There are many benefits to choosing a load balancing configuration, including:

  • The scalability of the platform enables you to add extra servers to your cluster as the number of visitors that you receive to your website grows
  • A load balancing cluster can offer you up to 100% guaranteed uptime when managed by a professional support team.

As well as being a suitable solution for distributing the load placed on web servers, load balancing is a solution that can also be introduced to a number of other services and applications that you can use in the server environment. Linux server-based load balancing is most suitable for web servers, although network-based load balancing allows you to introduce the use of different protocols so more advanced applications can be scaled through load balancing.
