Load Balancer (LB) for Application servers

A Load Balancer or LB (also referred to as an Application Load Balancer) is used to evenly distribute large amounts of traffic across a network, enabling it to function more efficiently.

An LB must be used when there are two or more application servers configured as an application cluster.

This chapter uses the F5 BIG-IP Local Traffic Manager (LTM) for all of its examples. However, any Load Balancer that supports the following configurations can be deployed.

Supported Servers

A load balancer supports clustering of Application servers.

Redundant Mode (Optional)

If a disaster recovery mechanism with active and passive Data Centers is required, the customer can deploy two load balancers configured as redundant where one serves as the primary and the other the secondary.

Routing Profile

Routing profile can be TCP based (layer 4) or HTTP based (layer 7).

Load Balancing Method

All load balancing methods are supported. It is recommended to use Least Connections or Round Robin load balancing methods, for better distribution between Application servers.
