I'm new to Elastic Beanstalk and I have a "simple" problem with where the EC2 and RDS instances are created. For a couple of hours now of creating, deleting enviroments and googling for solutions I'm out of ideas.
The problem seems quite simple. I want the EC2 and RDS instances in the same Availability Zone so that I don't have to pay for the traffic between Availability Zones. But it seems the zones in which they are created are random (1a-1c). In the "Configuration" tab I see that under Instances "Availability Zones: Any" is configured. But when I edit the instance configuration there is no option to change it.
The actual zone doesn't matter. Important is only that all instances are created in the same zone.
Thank You.
