About CloudBurn
CloudBurn is a cutting-edge tool tailored for teams leveraging Terraform or the AWS Cloud Development Kit (CDK) to manage cloud infrastructure. It aims to eliminate costly infrastructure errors before they reach production, a critical concern in today's fast-paced cloud environment. Often, teams are surprised by unexpected AWS costs that surface weeks after deployment, leading to budget overruns and financial strain. CloudBurn mitigates this risk by integrating cost visibility directly into the code review process, allowing teams to evaluate the financial impact of their infrastructure changes in real-time. This proactive approach enables developers to engage in collaborative discussions about budget implications, ultimately leading to informed decision-making. By providing detailed cost reports during pull request reviews, CloudBurn not only enhances team collaboration but also ensures that infrastructure remains cost-effective and efficient, saving valuable time and resources.
