Server Load Balancing Configuration Options¶
There are four areas of configuration for the server load balancer:
- Pools define collections of servers to be used, which port they use, and the monitoring method.
- Virtual Servers define the IP address and port for accepting user connections, and the appropriate pool to direct the incoming traffic destined to that IP address and port.
- Monitors are used to create custom monitoring methods to determine if pool servers are working and usable.
- The Settings tab contains global options that alter how the load balancer operates.
In a typical example, there is a Virtual Server to accept user connections, and it contains several servers in a Pool. The Pool utilizes a Monitor for each server to determine if it is capable of accepting user connections.
A Virtual Server can have a regular and a Fall Back Pool to use if all members of the regular Virtual Server Pool are down. This can be leveraged to present a maintenance or outage page, for example.
