I want to configure active-passive failover with Route-53 in which primary (Active) resource is available/running and in case of any failure, Passive instance should take over.
I want to know how we need to configure Passive EC2 instance.
I am referring to the article Active-active and active-passive failover - Amazon Route 53.
In the given scenario, if Amazon Route 53 detects a failure, it simply sends the traffic to the alternate instance.
That instance should already be fully configured ready to process any traffic it receives.
It should use the same instance configuration as 'Active-Active', except it doesn't get any traffic when the primary instance is operating correctly.
