F5 VE in AWS HA config

Shazee

F5 VE with 2 NICs.

One facing Private and other facing public subnet. (1.0 - Facing Private and 1.1 Public )

(Both Private and Public are RFC 1918 addresses as F5 resides below a NLB in AWS )

Management is through private ip address range .

I could not find a support document to configure HA across multiple availability zones ( 1 VPC with 3 AZs )

Would like to configure the device cluster and config sync only through private subnet.

HI Shazee, have you tried to do a test deploy of the CFT template we have on our F5 Networks GitHub? The templates currently deploy with single-nic BIG-IP instances when going behind a tier 1 device for autoscaling. Do you have a requirement for 2-nics?

I have a question if they are across az, should they go under elb anyway? Could you handle it directly with elastic ip?

If you want across AZ, then we have a few options there too. You can use an AWS LB in front...or you can failover by using the scripts loaded into the BIG-IP VM instances which use the Cloud Failover Extension by F5 for HA.
