During April 2025, Daisy Marie Bernante developed a new Container Cost Usage API endpoint for the alphauslabs/blueapi repository, focusing on enhancing cost visibility for containerized workloads. She designed and implemented the GetContainerCostUsage RPC using Protocol Buffers and gRPC, enabling users to filter, group, and analyze cost and usage data with flexible time granularity. Her work included adding CPU and memory utilization metrics, refining request and response models, and adjusting API paths for consistency. This feature supports cost governance and optimization by providing granular insights, reflecting a thoughtful approach to API development and data modeling within a cloud cost management context.
