Build, test, distribute, and promote Packer machine images with pinned inputs, launch checks, regional validation, and an auditable rollback path.
Bring unmanaged cloud resources under Terraform with import blocks, stable addresses, provider-specific IDs, safe plans, and a repeatable adoption workflow.
