[Pdns-users] [E] Re: Powerdns on AWS Instances

[Giovanni Vecchi]

Hi Chhavi,

I can confirm you can use AWS ELB (Network Load Balancer) in order to Load
Balance DNS queries: I configured it too in our production environment.
I created a single target group containing all the EC2 instances where rec
is installed in order to balance 53/UDP port and 53/TCP is used for health
checks.
No problem for more than a year now.
