Infrastructure as Code with Terraform Instead of a manual process to setup and configure our technology stack, we want to automate this proces through software. Hashicorps’ Terraform (2014) enables a declarative (vs. imperative/procedural) approach to Infrastructure as Code. Although it is claimed to be cloud agnostic, Terraform is certainly not. The configuration will depend strongly on the naming and organization of the specific provider. But we can make at least the top-level infrastructure more cloud-agnostic by using the following two-level approach:...
Implement PostgREST, a standalone web server that turns your PostgreSQL database directly into a RESTful API.
