Normally, within LAN environments you would not need to have something like HACC. In a LAN we can create any IP within our IP segment, address it, and utilise it when we need to. This is not the case within Cloud environments are compartmentalised and highly restricted in terms of users being able to do what every they wish.
This means that setting up load balancers in HA pairs is extremely complex and requires the use of the cloud providers own load balancer to distribute the ‘elastic’ IP.
HACC has been designed and built to alleviate this issue allowing users to have HA pairs of load balancers without the use of the cloud provider load balancer as a IP address distributor.
