We have two Nginx running and first Nginx receives the traffic after checking some rules forwarding the traffic to another Nginx, now we are moving this to AWS ALB, but not found any option for forwarding traffic from one ALB to another ALB.
Please help me on how to do this.
I know these two ALB is a Design problem but at this point in time we can not change this, the team will do this in the future.
Unfortunately you forward traffic only from NLB to ALB. As far as I know AWS does not support forwarding from ALB to ALB. You can sort of cheat on it by create a fixed IP target group, but this is not very stable because ELBs IP addresses can change any time without notice
