What is the best way to implement code versioning and sharing among Infrastructure DevOps Engineers using Terraform?

Storing Terraform code in a version-control system is the best practice for implementing code versioning and sharing, particularly among Infrastructure DevOps Engineers. A version-control system provides numerous benefits that are essential for managing code effectively in a collaborative environment.

Primarily, a version-control system tracks changes to the codebase over time. This means that any modifications made can be easily reviewed, rolled back, or reverted if necessary. For teams, this capability is crucial to ensure that changes are well-documented and that any introduced issues can be traced back to specific changes. Additionally, this system supports branching and merging, allowing team members to work on different features or fixes simultaneously without disrupting each other's work.

Furthermore, using a version-control system enhances collaboration. Team members can comment on changes, review each other's code, and merge contributions in a controlled manner. This helps maintain code quality and encourages code reviews, which can lead to improved security and best practices within the infrastructure code.

Options that involve using a network shared folder, a Cloud Storage bucket, or a shared Google Drive folder do not provide the same level of tracking, collaboration, and management features as a dedicated version-control system. These alternatives may allow for sharing copies of the code, but they typically lack robust revision histories,
