F5 BIG-IP HA LTM in Azure

deploying ltm ha pair in azure

This post goes through the deployment of a HA pair of F5 BIG-IP LTMs in Azure. Like with most vendors the F5 solutions is documented as part of ARM templates, I personally prefer to pick these things apart and first build them manually to better understand what is going on under the hood. A more cynical person may suggest they do this on purpose to try and hide all the fudges needed to make their solution work in a public cloud.

F5 BIG-IP DNS Express

using big-ip dns express as a local dns server

As part of a POC I deployed a pair of HA F5 LTM/GTM at home to use for all things DNS based. It is an indulgent over the top DNS solution for a 1 bed flat, but hey-ho we are in a pandemic….. This guide does not go through the HA F5 or GTM (still cant stop calling it that) configuration, it is focussed around using ZoneRunner for DNS (bind) with these zones transferred into DNS express and serviced by a listener.
