Purpose of Server Load Balancing
An application switch increases website availability by allowing for web servers to fail
(or be shut down for maintenance) without a website outage. It also improves the
response times of the website and increases the traffic-handling capacity of the website
by allowing multiple servers to be used together as a single site.
