Hi shadow_82,
I strongly advise against building a failover cluster in the cloud. Resources in the cloud are far to expensive to use them in standby mode. Failover might take longer than expected (=bad customer experience).
I do recommend to have an active/active setup and utilize GSLB as a service (F5 DNS Load Balancer Cloud Service) to distribute traffic between the two instances. Use Terraform / AS3 (any form of automation) to keep the config on both BIG-IP nodes consistent.
If you insist on using failover - this is how it's done the F5 way: https://clouddocs.f5.com/products/extensions/f5-cloud-failover/latest/

Thanks for answer!
This is something we are thinking about, maybe not active active due to heavier troubleshooting once something bad occurs (you have to divide traffic going though 2 F5s, not 1).
Yet maybe having only 1 F5 running and second being shut down in cluster - until some upgrade procedure will be needed.
This might be the sweet spot.
You pay for 1 VM running 24/7/365 and spin up the 2nd one for upgrade purposes (to switchover)
