Resource Dependencies in Terraform

Mastering Resource Dependencies in Terraform

When you first begin working with Infrastructure as Code (IaC), it is easy to view your configuration files as simple lists of instructions. You write a block for a virtual machine, a block for a network, and a block for a database, and you expect Terraform to simply "make them happen." However, infrastructure is rarely a collection of isolated components. In the real world, a database cannot exist without a network to host it, and a virtual machine cannot launch without a subnet to reside in.
