About Server Load-Balancing (SLB):

Server Load-Balancing is a process and technology that distributes site traffic among several servers using a network-based device. This device processes traffic targeted at a site and redirects that traffic to various servers (nodes) distributing the load across multiple machines creating a vast virtual server. This load balancing process is completely transparent to the end user and there can be anywhere from 2 to hundreds of servers operating behind a single URL.

In summary, a load-balancer will:

• Process traffic destined for a site.

• Split traffic into individual requests and decides which servers receives those requests.
• Maintains a watch on the available servers (nodes), ensuring they are responding to traffic and if they do not, remove them from rotation.
• Provides redundancy by employing more than one unit in a a fail over scenario (High Availability).
• Offers content-aware distribution, by doing things such as processing URLs and routing traffic based on portions of the URL, intercepting cookies, and XML parsing.
