Overview

Take control of cloud spending before it snowballs. In this step-by-step Shift-Left FinOps guide, you’ll weave Infracost into your everyday workflow—running price checks on every Terraform plan, surfacing clear dollar estimates in GitHub pull requests, and blocking code that breaks your budget. You’ll start by installing the Infracost CLI on Linux, macOS, or Windows, then run a five-minute local test to see live AWS, Azure, or Google Cloud prices right in your terminal. Next, you’ll drop a lean GitHub Actions workflow into your repo that posts an easy-to-read cost table, sets a hard monthly-spend threshold, and fails the build when changes exceed it. Along the way you’ll learn simple tweaks—usage files, Slack alerts, custom discounts—that turn one project into an organization-wide cloud cost guardrail. Whether you’re a DevOps engineer, SRE, or FinOps champion, this tutorial shows how to catch expensive resources early, align engineering and finance, and ship features without surprise bills—all in under an hour.
