3.2 Load balancing
Load balancing is used to distribute requests to be processed to multiple Application Servers to balance the load of processing requests. To use this functionality, use the hardware load balancer or software load balancer.
Selecting the load balancing method
For load balancing, use either the hardware load balancer or the software load balancer. Application Server provides a load balancing functionality that uses Web Server as the software load balancer. This functionality distributes processing across servers according to the number of requests.
The following table compares the hardware load balancer and the software load balancer with regard to installation cost and functionality.
