Terraform simplifies and accelerates the configuration and deployment of infrastructure, including cloud-based environments. In this project-based course, David Swersky highlights a series of advanced Terraform use cases. David goes over the steps to create a new Terraform configuration, then explores intermediate concepts like variables, looping, expression and functions, modules, and more. He explains advanced concepts, such as custom modules, defining a remote state backend, and deploying configurations across multiple environments. The course is capped with an example model for a complete Continuous Integration/Continuous Delivery pipeline for deploying Terraform configurations.
