Your DIY Internal Platform Costs One Full-Time Engineer: What Actually Replaces the Terraform + Helm + ArgoCD Glue?

A Qovery-authored comparison argues that maintaining a homegrown internal platform based on Terraform, Helm, and Argo CD can consume 0.5 to 1.5 engineering roles annually through upgrades, configuration drift, security work, access requests, and platform on-call responsibilities, potentially costing $90,000 to $300,000 per year. It recommends retaining Terraform for foundational cloud infrastructure such as accounts, networking, IAM, and shared services while using bring-your-own-cloud (BYOC) internal developer platforms for application environments, deployment pipelines, preview environments, RBAC, and Kubernetes lifecycle tasks. The piece distinguishes full BYOC platforms including Qovery, Northflank, LayerOps, and Bunnyshell from managed GitOps products such as Akuity and Codefresh, which primarily manage Argo CD, and from tools like Crossplane and Backstage, which it says still require substantial operational ownership. It proposes evaluating platforms through a short trial using a real application, measuring deployment speed, configuration effort, preview-environment setup, RBAC, and exit options, then migrating incrementally over four to eight weeks with a parallel run. It also notes that a DIY platform may remain appropriate for organizations with specialized, regulated, air-gapped, or highly customized infrastructure needs, or with a sufficiently staffed platform team treating it as a product.
