Multi-Cloud Cost Management Platform with FOCUS
Ba-Hung Nguyen, Nishijima Nao, Hitoshi Yabusaki · 2025
Managing costs across multiple cloud service providers (CSPs) is challenging due to each platform's unique data formats and billing models. We propose a service-oriented Multi-Cloud Cost Management Platform (MCCMP) that treats each CSP's cost exports as independent services, unified under the FOCUS specification. This approach simplifies cross-provider cost comparisons and fosters modular integration, allowing new CSPs or features to be added with minimal disruption. We further illustrate an anomaly detection (AD) capability using MLOps to demonstrate the system's extensibility for advanced analytics. We present our initial findings on the system architecture, data normalization process, and partial AD results, including early validation showing an AUC of 0.885 for anomaly detection and ingestion latencies under one minute.
