5 Expensive Terraform Mistakes I Keep Seeing in Real Infrastructure and How AI can Help

Small infrastructure decisions that quietly turn into large cloud bills Infrastructure-as-Code has dramatically improved how teams manage cloud environments. Terraform in particular has made it possible to define infrastructure in version-controlled, repeatable configurations. In theory, this should make infrastructure both predictable and efficient. In practice, however, Terraform does not automatically make systems cost-efficient. It simply makes infrastructure changes easier to reproduce. If inefficient patterns exist in the configuration, Terraform will reproduce them perfectly. Over time, small infrastructure decisions accumulate. Many of them appear harmless when introduced, but months later they become visible as unexpectedly large cloud bills. Here are some of the most common Terraform patterns I keep seeing that quietly drive up infrastructure costs. 1. Oversized Compute That Never Gets Revisited One of the most common patterns starts early in a project. During initial develop
