December 2025 Summaries

The ICT sector is responsible for approximately 1.5 to 4 percent of global greenhouse gas emissions, comparable to the aviation industry, highlighting the significant environmental impact of digital infrastructure. Engineers often make infrastructure decisions without visibility into the environmental or financial impact of these choices. To address this, Infracost Cloud has introduced InfraCarbon, a tool that shows the carbon impact of infrastructure changes directly in pull requests, alongside cost information, making the environmental impact of decisions more tangible and relatable. Developed in partnership with Greenpixie, InfraCarbon provides real-time carbon equivalences, such as flights avoided, to motivate engineers to make more sustainable choices. This initiative aligns cost efficiency with carbon reduction, offering a dual benefit of environmental responsibility and financial savings, while also contributing to a growing emphasis on sustainability in corporate reporting. By integrating carbon insights into the existing workflow, InfraCarbon aims to shift decision-making to a more informed and sustainable approach, fostering a broader ecosystem around FinOps and sustainability.

AWS announced a price reduction for RDS SQL Server on M7i and R7i instances, prompting the need for continuous monitoring of cloud infrastructure costs, which can fluctuate due to evolving prices, new instance types, and storage tiers. Infracost addresses this challenge by tracking price changes and identifying opportunities to optimize existing infrastructure, allowing users to make informed decisions about upgrades and rightsizing. The Issue Explorer feature provides estimated annual savings for detected issues and allows users to filter by savings thresholds and group issues by tags to better manage and prioritize optimizations. Infracost Cloud facilitates organization-wide coordination for modernization efforts with features like Campaigns and AutoFix, which can automatically generate necessary code changes. The platform's data export capabilities enable integration with existing tools, enhancing the ability of engineers, executives, and managers to act on cost-saving insights.

Infracost has developed a sophisticated approach to cloud security governance by integrating deep parsing capabilities for infrastructure-as-code (IaC) tools like Terraform, CloudFormation, and AWS CDK. This allows them to evaluate and understand the actual infrastructure configuration rather than simply analyzing text patterns. By leveraging this foundation, Infracost has introduced Cloud Security Policies that enable proactive cloud security posture management (CSPM) checks directly within developers' existing workflows, specifically in pull requests, thus enhancing the shift-left approach in security. The system automatically detects IaC repositories across platforms such as GitHub, GitLab, or Azure Repos, eliminating the need for manual configurations and maintaining developer focus without switching tools. Infracost's Campaigns feature provides a control plane for governance, allowing enterprises to monitor and direct security efforts strategically by tracking metrics like the prevention of new issues and the remediation of existing ones. With the launch of 22 customizable policies covering AWS and Azure services, Infracost aims to empower developers and platform teams to prioritize security and FinOps concerns effectively, while planning to expand its offerings based on customer feedback.

Engineers often reuse Terraform code without considering potential cost implications, such as using outdated database versions or expensive storage configurations, leading to unexpected cloud expenses. These oversights are not due to negligence but rather the result of prioritizing quick and reliable deployment, as engineers typically aren't aware of extended support fees or outdated defaults like AWS's gp2 volumes. In response, new FinOps policies have been introduced to preemptively address these issues, covering AWS services with extended support fees and flagging inefficient storage defaults. Additional policies target non-production environments, encouraging appropriate configurations to prevent unnecessary expenses. The policies also promote the use of negotiated discounts by steering engineers towards preferred configurations and provide metadata to assess the risk and effort involved in implementing changes. These enhancements, available in Infracost Cloud, aim to optimize cloud spending by enabling organizations to catch cost issues early, with customizable risk assessments and Autofix suggestions facilitating informed decision-making.

AWS CDK presents an appealing option for engineers seeking a unified approach to application and infrastructure code by allowing the use of a single programming language, such as TypeScript or Python, throughout the development process. However, this choice previously involved a trade-off in cost visibility compared to Terraform. Infracost Cloud now addresses this gap by natively supporting AWS CDK, offering cost estimates and policy enforcement for TypeScript, JavaScript, and Python without requiring changes to existing pipelines. This integration provides engineers with immediate feedback on infrastructure costs and potential code issues directly within their workflow, highlighting specific lines of code that need modification. Developed in collaboration with community engineers, this feature aims to enhance cost visibility by fitting seamlessly into developers' existing practices. While currently available in early access, further enhancements, including CLI and IDE support, are planned for the future.

Infracost has announced the integration of AWS CloudFormation support into Infracost Cloud, allowing teams to proactively estimate and manage cloud costs before deployment, similar to its existing support for Terraform. This development addresses the challenge faced by organizations using AWS CloudFormation, enabling them to reduce cloud waste and optimize expenses before code is merged. By analyzing CloudFormation templates directly, Infracost provides cost estimates in every pull request, enforces FinOps and tagging policies, and offers unified visibility across different infrastructure as code (IaC) frameworks. This integration was driven by community feedback, with extensive input from engineers on GitHub shaping its development. The CloudFormation support is currently available in early access, with future plans to expand CLI and IDE support by 2026.
