SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps review Terraform-based AWS infrastructure for unnecessary cost, making it easier to keep non-production environments affordable without sacrificing production reliability.

Core Features & Use Cases

  • Resource Cost Inventory: Catalog every cost-driving AWS resource across networking, compute, storage, database, monitoring, and security.
  • Environment-Aware Optimization: Check whether expensive resources can be disabled, resized, limited, or retained differently across dev, staging, and production.
  • Practical Use Cases: Review a new VPC module before launch, diagnose a surprising AWS bill, or recommend environment-specific overrides for Atmos stacks.

Quick Start

Ask the skill to review the Terraform component for cost traps and recommend dev, staging, and production settings.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check my Terraform AWS infrastructure for cost optimization opportunities?

You catalog cost-driving AWS resources across networking, compute, storage, and databases, then validate their toggleability, sizing, scaling, retention, and tier selection to identify right-sizing opportunities across dev, staging, and production.

What is Terraform right-sizing and how does it help with FinOps?

Terraform right-sizing analyzes AWS components to resize, limit, or disable expensive resources based on environment needs, directly supporting FinOps by controlling infrastructure costs without sacrificing production reliability.

Can I use this to review Terraform modules before launching a new VPC?

Yes, you can review new Terraform modules before launch by inventorying cost-driving resources and checking for environment-aware optimization, ensuring affordable non-production environments without sacrificing production reliability.

How do I investigate a surprising AWS bill using Terraform configurations?

To investigate a surprising AWS bill using Terraform, review your infrastructure components to catalog cost-driving resources and validate their data transfer controls, retention policies, and tier selection for cost traps.

Does this work with Atmos stack variable planning for environment-specific overrides?

Yes, it works with Atmos stack variable planning by recommending environment-specific overrides, checking whether expensive resources can be disabled, resized, limited, or retained differently across dev, staging, and production.

What's the best way to keep non-production AWS environments affordable with Terraform?

The best way to keep non-production AWS environments affordable is to review Terraform components for cost traps, validating that expensive resources can be toggled off, resized, or limited differently than production settings.
