While Terraform ironically serves as a strong defense against cloud provider lock-in through its multi-cloud HCL approach, it introduces its own tooling and platform lock-in risks. The post covers five types of lock-in, compares Terraform against CloudFormation, Pulumi, OpenTofu, and Bicep, and offers practical mitigation strategies: keeping modules provider-aware, using portable state backends, avoiding over-adoption of proprietary platform features, maintaining OpenTofu compatibility, and pinning versions. OpenTofu is highlighted as the most direct answer to tooling lock-in, offering the same syntax and providers under open CNCF governance. ## Full article daily.dev links to this article rather than hosting it.
