Create the Internal Load Balancer (ILB)

An Azure Internal Load Balancer must be deployed to monitor the health of the LoadMasters and direct traffic accordingly.

There are several settings that need to be configured to provide the high availability of the LoadMasters:

• Create a back-end address pool and add the LoadMasters to the pool.
• Create Inbound NAT rules to direct traffic to the appropriate LoadMaster.
• Create a Probe to monitor the health of the LoadMasters.
• Create Load Balancing Rules to allow the necessary traffic.

Refer to the sections below for further information on each of these.
