Here's a real-world benefit I had over the weekend. I've been using Terraform for a Google Cloud project, and was coming to setting up DNS records. I wanted to have dual DNS providers for redundancy. With Terraform, it was trivial, as I just added a second Terraform resource for DNSimple (with Google Cloud DNS as my 'main' DNS resource).

The beauty of Terraform is that you can orchestrate all of your infrastructure, not just the stuff in one stack. If you've got 95%/4%/1% in AWS/Azure/GCP, how do you manage/reference the non-AWS resources? Terraform gives you a unified way to reference and link cross-infrastructure resources.
