Having the ability for the HVR to pull/sync a config file from Github etc would be a vast improvement over editing the config file by GUI. It does not have to be terraform but that would be a good example. Making/controlling changes through IaC would have the following benefits.

1. Automation and Consistency: IaC allows you to automate the provisioning and management of infrastructure, ensuring that environments are consistent and repeatable. This reduces the likelihood of human error and configuration drift.

2. Scalability: By using IaC, you can easily scale your infrastructure up or down based on demand. Tools like Terraform enable you to manage infrastructure for multiple environments (development, testing, production) in a consistent manner.

3. Version Control: Infrastructure configurations can be stored in version control systems like Git. This allows you to track changes, collaborate with team members, and roll back to previous versions if something goes wrong.

4. Testing and Validation: IaC allows for the testing and validation of infrastructure changes before they are applied to production environments. This helps in identifying potential issues early in the development cycle.
5. Documentation: IaC serves as a form of documentation for your infrastructure. Anyone in the team can understand the setup and configuration by reading the code, which improves collaboration and reduces reliance on individual knowledge.
