(4) APM VE's Active-Active-Active-Active 15.x

We plan to have (4) 25M F5 15.x APM VE’s up at the same time each supporting 5000 max sessions. We would like all 4 APM's active at a time and share the sessionID cookie between all four in the instance of an APM failover event.

 

The below article is the most relevant I have found, but it seems a bit contradicting

 

K13983: BIG-IP APM HA deployments

https://support.f5.com/csp/article/K13983

 

Do you know if it’s saying to have each APM in a separate traffic-group? (traffic-group-1, traffic-group-2, traffic-group-3, traffic-group-4,

And then create a “Sync-only” traffic-group-1 in all (4) APM’s for the APM policy configuration?

 

Or is it better to create all (4) F5 APM VE’s as standalone? And just have a Sync-only traffic-group-1 on all four APM’s?

 

Thanks!

TJ

    Hi TJ,

     

    in an ideal world, I'd suggest you to have 4 standalone APM instances. Configuration must be kept consistent among all four devices, this could be achieved with either BIG-IQ or AS3. Or another orchestration tool of your choice. For loadbalancing and in order to assure persistence I'd either use the F5 DNS Load Balancer Cloud Service or BIG-IP DNS.
