'Infrastructure as Code' (IaC) refers to the practice of managing and provisioning computing infrastructure through machine-readable definition files rather than through manual processes. This approach allows for improved automation, consistency, and efficiency in managing infrastructure. By using code to define infrastructure components, such as servers, storage, and networking resources, teams can apply software development principles to infrastructure management.

The use of definition files, which may be written using configuration languages (like YAML, JSON, or domain-specific languages), enables version control, repeatability, and the ability to easily replicate environments. This means that developers and operations teams can review changes, test configurations, and deploy infrastructure in a manner similar to developing and deploying applications. The benefits of IaC include reducing configuration errors, speeding up the deployment process, and improving collaboration between development and operations teams.

The other choices do not capture the essence of IaC. Writing code in multiple programming languages does not specifically relate to infrastructure management. Deploying infrastructure manually contradicts the principles of IaC by promoting manual intervention instead of automation. Developing software exclusively in the cloud is unrelated to the core concept of defining and managing infrastructure programmatically.
