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/
