Cloud architects and DevOps engineers want tools that allow for faster development and deployment. Infrastructure as code principles treat infrastructure like code, enabling validation and knowing what changes were made. Open-source tools like Terraform, cloudcraft.co and the Terraform AWS modules help architects and engineers visualize, code, and build AWS infrastructure in a standardized way. Modules.tf is a free, open-source tool that generates Terraform code from cloudcraft.co diagrams to help bootstrap infrastructure setup.
