Architecture

Terrascan’s architecture is built to be modular to facilitate adding IaC languages and policies. At a high-level it is composed of the following architectural components: a command-line interface, API server, runtime, pluggable IaC providers, pluggable policy engine, notifier, and writer.

• Command Line Interface = Provides CLI input to Terrascan.
• API Server = Provider input to Terrascan through an API.
• Runtime = Performs input validation and process inputs
• IaC Providers = Converts IaC language into normalized JSON
• Policy Engine = Applies policies against normalized JSON
• Notifier = Providers webhooks for results of Terrascan scans.
• Writer = Writes results into various formats like JSON, YAML, or XML.
