Developed a granular networking costs breakdown feature for the spotinst/openapi repository, enhancing the Aggregated Costs API to provide detailed visibility into networking expenses within AKS clusters. Focused on API design and schema definition using YAML, the work introduced a new networking object that enables precise attribution of costs for internet traffic, inter-AZ, intra-AZ, and inter-region usage. The implementation maintained backward compatibility and stable performance, ensuring seamless integration with existing workflows. This addition empowers teams to analyze and optimize networking-related spend more effectively, supporting actionable insights for cost control and resource allocation across diverse cloud environments without disrupting current operations.
