  Tutorial: Load Balancing Web Applications

Load Balancing Web Applications an overview of several approaches to load balancing on Web application server clusters. A cluster is a group of servers running a Web application simultaneously, appearing to the world as if it were a single server. To bal

Tutorial Details:

When you enter a URL in a browser (say, www.loadbalancedsite.com), the browser sends a request to the DNS asking it to return the IP address of the site. This is called the DNS lookup. After the Web browser gets the IP address for that site, it contacts the site using the IP address, and displays the page for you.

The DNS server generally contains a single IP address mapped to a particular site name. In our fictional example, our site www.loadbalancedsite.com maps to the IP address 203.24.23.3

To balance server loads using DNS, the DNS server maintains several different IP addresses for a site name. The multiple IP addresses represent the machines in the cluster, all of which map to the same single logical site name.
