The text discusses patterns for refactoring infrastructure as code to comply with organizational standards. It highlights the importance of standardizing applications, infrastructure, and security to streamline compliance and remediation at scale. The article introduces policy as code and immutability as key concepts to support refactoring efforts. Policy as code automates, documents, and versions policies, while immutability reduces complexity, minimizes disruption, and scales for larger use cases. By adopting policy as code and immutability, organizations can speed up discovery and remediation, reduce risk fragmentation, and improve the efficiency of standardizing platforms and resources. The article provides examples and guidance on implementing policy as code, using immutability in migrations, and applying these concepts to refactoring across multiple platforms.
