Everything as Code with Terraform
The document discusses the concept of 'everything as code' particularly using Terraform for infrastructure automation. It emphasizes the importance of unifying resources, supporting modern data centers, and making infrastructure changes predictable across different technology platforms. Additionally, it includes examples and tips for building custom Terraform providers and highlights the potential for various aspects of life and work to be automated through code.
