Infrastructure as Code (IaC) has become the backbone of modern cloud operations, but migrating existing cloud configurations to Terraform can be a time-consuming and error-prone process. This analysis examines a real-world project where I used an agentic coding assistant (specifically Roo, but any agent will work) to migrate our entire cloud infrastructure configuration from manual management to a comprehensive Terraform codebase. The backend LLM model was Claude 3.7 Sonnet, accessed via AWS Bedrock. ...
