Example Concept: Use Terraform's state management and modules to prevent configuration drift by defining infrastructure as code. Store the Terraform state in a remote backend like AWS S3 with state locking enabled via DynamoDB to ensure that only one process can modify the state at a time. Organize your Terraform code into reusable modules that define the infrastructure components, and use workspaces or separate state files to manage deployments across multiple regions. This setup allows you to apply the same configuration consistently across regions, minimizing the risk of drift.
