Question

A new engineer joins a team that manages its entire cloud footprint with Terraform. On their first day, they need to understand exactly what resources exist, how they are configured, and how components relate to each other. There is no separate architecture wiki. Which advantage of Infrastructure as Code best helps the new engineer answer these questions?

Accepted Answer

The Terraform configuration files serve as self-documenting source of truth describing the intended infrastructure and its relationships

Answer

IaC guarantees that the cloud provider automatically generates an up-to-date architecture diagram on every deployment

Answer

Terraform continuously emails the team a written summary of all running resources each morning

Answer

IaC removes the need to understand the infrastructure because everything is fully abstracted away from engineers
