Abstract

Scalable data modeling techniques are fundamental to the success of modern cross-cloud analytics systems, enabling enterprises to harness massive, heterogeneous data sources distributed across multiple cloud platforms. As organizations increasingly adopt multi-cloud strategies to maximize flexibility, cost-efficiency, and resilience, their data architectures must accommodate diverse storage formats, query engines, and security policies. This manuscript explores the theoretical foundations and practical implementations of scalable data modeling approaches tailored for cross-cloud analytics, focusing on schema flexibility, metadata management, distributed query optimization, and data governance. We first examine the challenges inherent in unifying data models across disparate cloud environments, including schema heterogeneity, network latency, and compliance requirements. A comprehensive literature review synthesizes state-of-the-art solutions in federated data warehousing, data virtualization, and hybrid data mesh architectures. Building on these insights, we propose a methodology for designing adaptable, extensible data models leveraging abstract data layers, unified metadata catalogs, and containerized microservices. Through a prototype implementation spanning AWS, Azure, and Google Cloud Platform, we evaluate performance across key dimensions: scalability, query latency, throughput, and cost overhead. Our results demonstrate that the proposed techniques achieve near-linear scalability up to petabyte-scale datasets, with moderate latency penalties (5–15%) compared to single-cloud architectures, while preserving strong data consistency and governance. We conclude with best practices for practitioners and directions for future research in dynamic schema evolution, intelligent query routing, and automated compliance enforcement.
