Using BIG-IP GTM to Integrate with Amazon Web Services
Altostratus"What is odd - the LTM you can put pool members with a FQDN but not with the GTM Pool members those must be a IP or server."
That's not actually correct. You can use a Wide IP or an FQDN as a static entry as pool members.
In my work environment we use FQDNs when we don't care about health checking and Wide IPs when we do. We rely on federation with LTMs that are able to resolve our cloud endpoints and health check them. It's an object heavy configuration, but it does work.
NimbostratusWhy not just use a script for the health monitor on the GTM? We are trying to figure out a way to load balance between internal and external AWS resources to save $$$.
We have several issues and I think right now the big one is ensure health checking against the FQDN. Which maybe using a "Scripted" health check approach would be the answer so we can keep all of this on the GTM.
Another issue we are hitting is randomly some of the AWS won't resolve every time. Wondering if it has to do with caching so looking to try and simplify maybe our solution.
