Which method allows for configurations to be scripted and automated, thereby reducing human error?

The method that allows for configurations to be scripted and automated, thereby reducing human error, is Infrastructure as Code (IaC). This approach enables infrastructure to be managed using code and automation tools, letting teams define and provision infrastructure through programming languages or domain-specific languages. As a result, configurations can be consistently deployed and replicated, minimizing the potential for manual errors that can occur with traditional configuration management.

Infrastructure as Code facilitates version control, testing, and continuous integration/continuous deployment (CI/CD) practices, which contribute to a more reliable and efficient deployment process. By automating the setup and management of infrastructure components, organizations can achieve greater scalability and adaptability while ensuring that configurations remain consistent across different environments.

In contrast, Configuration as Code pertains to the management of software configurations and environment setups but does not encompass the broader management of infrastructure required for comprehensive automation. Automation as Code and Scripted Configuration also deal with automation, but they do not provide the full framework and processes for integrating into entire infrastructure management as Infrastructure as Code does.
