Infrastructure as Code at Thomson Reuters with AWS CDK

Thomson Reuters developed an AWS CDK extension library to standardize and automate infrastructure management, addressing challenges in cloud resource creation and compliance across large organizations.

• Created a monorepo approach to manage CDK packages and modules
• Developed a core module that "TR-ifies" AWS resources by:
  • Enforcing naming conventions
  • Applying security and financial optimization policies
  • Standardizing resource tagging
• Used TypeScript module augmentation to extend AWS CDK constructs
• Simplified resource creation by automatically generating compliant resource names
• Provided easy access to centrally managed landing zone resources

The solution reduces infrastructure management errors, enhances governance, and accelerates development by providing a minimally invasive framework that works with standard AWS CDK code.
