AWS Connect automation scripts

In Terraform, most resource dependencies are handled automatically. It analyses expressions within a resource block to find references to other objects, and treats those references as implicit ordering requirements when creating, updating, or destroying resources.

However, there are some resources that have hidden dependencies and must be explicitly defined by using depends_on.

I've seen a few IaC documentations that mention if you need to explicitly define the dependency but sometimes it doesn't. One way to find out is to test your configuration.
