There are many studies on how widespread the problem of overprovisioning the cloud infrastructure is. A typical approach to mitigating this problem is monitoring your infrastructure and making the proper downscaling decisions.

We'll review the idea of defining the system usage model in code using the CUE language and see how it can be used to derive the Terraform configuration.
