F5 GTM Clustering with all in One VM

Hi,

GTM works as a standalone product regardless of LTM Device Clustering. As long as you have a minimum of 1 GTM configured somewhere you can do intelligent DNS (GSLB) using wideIPs that would resolve with LTM VIPs from both DC. For DNS redundancy it's of course best to have several.

You may choose to have 1 GTM on each DC (total 2) or 1 GTM on each BIG-IP (total 3). For GTM on your LTM cluster, you can choose to use a unique listener IP for each GTM, or to use a floating IP as the listener.

There isn't a best way to do things, it depends on your infrastructure, constraints, requirements and budget really. I suggest you document yourself further on AskF5 on how to implement GTM as you'll face other challenges along the way like setting up proper iQuery meshes between your devices. You could also contact F5 Professional Services so they can assist you with the design of your GTM solution based on your requirements.
