About CloudBurn
What if you could peer into the financial future of your infrastructure code before it ever runs? CloudBurn is a transformative tool designed for engineering teams who use Terraform or AWS CDK to manage their cloud infrastructure. It addresses a critical, often painful gap in the development lifecycle: the disconnect between writing infrastructure-as-code and understanding its cost implications. Traditionally, teams discover budget overruns weeks later on their AWS bill, long after resources are provisioned and costs are accumulating. CloudBurn fundamentally changes this dynamic by injecting real-time cost intelligence directly into the code review process. Whenever a developer opens a pull request with infrastructure changes, CloudBurn automatically analyzes the diff using live AWS pricing data and posts a detailed cost report as a comment. This creates a powerful feedback loop, empowering teams to discuss, optimize, and adjust expensive configurations while the changes are still in development and easy to modify. It’s a proactive shield against budgetary surprises, transforming cost management from a reactive, finance-led scramble into an integrated, engineering-led practice. It’s for any team that has ever wondered, "How much will this new architecture actually cost?" and wants an immediate, accurate answer.
Features of CloudBurn
Automated Pull Request Cost Analysis
Imagine every infrastructure change being automatically audited for its financial impact. CloudBurn integrates directly with your GitHub workflow to analyze the diff in every pull request. Using live AWS pricing data, it calculates the exact monthly cost delta of your proposed changes and posts a clear, itemized report as a comment. This happens within seconds, turning cost awareness into a natural, non-disruptive part of your team's review process without any manual intervention.
Real-Time AWS Pricing Intelligence
How can you trust a cost estimate if it's based on outdated data? CloudBurn eliminates this uncertainty by pulling the very latest pricing information directly from AWS. This ensures that every cost projection for resources like EC2 instances, Fargate tasks, or RDS databases is accurate and reflective of current on-demand rates, giving you confidence that the numbers you see are the numbers you'll get.
Seamless Integration with Terraform & AWS CDK
Wondering how to fit a new tool into your existing IaC workflow? CloudBurn is designed to work natively with the tools you already use. By simply adding a GitHub Action for either Terraform Plan or AWS CDK Diff, you connect your pipeline. The tool automatically detects the output, sends it for analysis, and delivers the cost report, requiring no changes to your core development practices or codebase.
Detailed, Actionable Cost Breakdowns
A single total cost figure is helpful, but what if you need to understand the why behind it? CloudBurn provides granular, line-item breakdowns for every resource change. You can see the hourly rate, usage type, and a plain-language description for each component, enabling developers to make informed optimization decisions, like downsizing an over-provisioned instance, right during the code review.
Use Cases of CloudBurn
Preventing Costly Misconfigurations in PR Reviews
The most effective way to manage cloud spend is to stop it at the source. Engineering teams use CloudBurn to catch expensive mistakes—like accidentally provisioning a dozen xlarge instances instead of micros—before the code merges. This shifts cost governance left, empowering developers with the data to self-correct and preventing heart-stopping surprises on the monthly invoice.
Enabling Data-Driven Architecture Discussions
How often do design debates hinge on performance but ignore cost? With CloudBurn, teams can elevate their architectural discussions. When proposing a new microservices design or database solution, the immediate cost impact is visible to everyone in the PR. This allows for balanced conversations that consider both technical merit and financial sustainability from the earliest stages.
Streamlining FinOps and Budget Forecasting
For platform and FinOps teams, manually forecasting the cost of upcoming projects is a tedious chore. CloudBurn automates this estimation process. By analyzing the infrastructure code slated for development, teams can generate accurate, code-based forecasts, improving budget accuracy and providing clear financial accountability for each project or feature team.
Educating Developers on Cloud Cost Implications
Many developers write infrastructure code without a clear understanding of the financial weight of their decisions. CloudBurn acts as a continuous learning tool. With every PR comment, developers receive immediate feedback on the cost consequences of their code, fostering a culture of cost consciousness and building institutional knowledge over time.
Frequently Asked Questions
How does CloudBurn calculate the cost estimates?
CloudBurn calculates estimates by parsing the infrastructure diff from your Terraform plan or AWS CDK synthesis output. It identifies the specific AWS resources being added, modified, or removed. Then, it cross-references these resources with real-time pricing data from AWS's own pricing API, applying the appropriate rates based on region, instance type, and other configurations to generate a projected monthly cost.
Is my code or cloud credentials exposed to CloudBurn?
No, your sensitive code and AWS credentials remain secure within your GitHub environment. CloudBurn operates by receiving only the textual output of your terraform plan or cdk diff command via a GitHub Action. Your actual Terraform state files, AWS access keys, or repository code are never transmitted to CloudBurn's servers, ensuring a secure and compliant workflow.
What infrastructure-as-code tools does CloudBurn support?
Currently, CloudBurn offers dedicated, seamless support for two of the most popular IaC frameworks: HashiCorp Terraform and the AWS Cloud Development Kit (AWS CDK). Support is implemented through easy-to-use GitHub Actions that capture the plan or diff output specific to each tool, making integration straightforward for teams using either standard.
Can CloudBurn analyze costs for existing infrastructure?
The primary focus of CloudBurn is on analyzing changes—the diff in a pull request. It is designed for pre-deployment cost visibility. For comprehensive cost management and analysis of your already-deployed, full infrastructure stack, you would typically use a cloud provider's native cost tool (like AWS Cost Explorer) or a dedicated cloud cost management platform.
