F5 BIG-IP DNS Review
Use Cases and Deployment Scope
Today we use it for Global Availability and HA across our multiple cloud regions and equinix facilities both internally and externally.
Pros
- Being able to create topology load balancing is very easy and straightforward
- It works really well to detect which region or state you are in to be able to load balance to the closest location
Cons
- We struggle with the fact that F5 BIG-IP DNS uses the LDNS. Today we use infoblox and we are able to tag ECS data so that the F5 can see the true source of the client but it would be cool if somehow that would work without having to forward.
- One thing that I also struggle with is the time stamps and adding new GTMS into the cluster. I have wiped out my deployment before because the timestamps we're wrong.
Return on Investment
- It has created an easy environment for us to onramp and load balance based on region into our GCP instances. This provides a faster experience for our customers increasing sales.
