HP Matrix Operating Environment 7.3 and 7.3 Update 1 Infrastructure Orchestration User Guide

Requesting a load balancer for an organization
Load balancers can be “reserved” for use by a particular organization or user by:
• Specifying a tag in the ioexec add loadbalancer command, and specifying that tag
on the Load Balance tab in infrastructure orchestration designer
• Ensuring that all networks visible to a load balancer are assigned to a specific organization.
In a template that has a logical network N that is visible to a load balancer, the actual load
balancer selected is determined by the network allocated to N by IO.
Creating and deleting a logical load balancer group
After a service has been deployed, IO administrators or an IO user can use the following ioexec
commands to create, manage, and delete logical load balancer groups.

NOTE: The create logical load balancer operation using the SOAP API or the ioexec CLI requires
administrator approval. The administrator is notified and the operation is paused until the
administrator clicks Approved on the infrastructure orchestration console Requests tab.
Other load balancer operations, such as deleting a load balancer group and adding or removing
group members, appear on the Requests tab but do not require administrator approval. These
operations do, however, require that a user name and password are supplied on the command
line.
The following figure shows an HAProxy load balancer configured to load balance the network
traffic between two servers in the Petclinic server group.
