Anton Babenko's Terraform Claude Skill is the biggest jump in AI-assisted IaC since Copilot. We tested it on a real AWS stack — VPC, EKS, S3 + KMS, IAM — and documented exactly what it fixes, what it misses, and what AWS teams should layer on top.
Terraform to OpenTofu migration: compatibility, risks, tools, and production deployment patterns for AWS infrastructure.
When dev works but production fails, it's almost always an environment parity problem. This guide covers building consistent environments across dev, staging, and prod—and the cost of not doing it.
Infrastructure drift—when your actual AWS resources differ from what your IaC declares—causes silent failures and makes disaster recovery impossible. Learn how to detect drift systematically and fix it before it breaks production.
CloudFormation works fine until your stack is 800 resources and a single update fails halfway. Stack organization, cross-stack references, drift detection, and the deploy patterns that keep production-scale templates safe to change.
Terraform is the multi-cloud default. CDK ships AWS features the day they GA. Language support, state management, multi-cloud flexibility, and the trade-off that determines which IaC tool fits your team — plus when running both is the right answer.
