Architecting a globally scalable data mesh: A case study demonstrating decentralized governance and a 30% reduction in data latency

Sana, Santosh Kumar (2025) Architecting a globally scalable data mesh: A case study demonstrating decentralized governance and a 30% reduction in data latency. World Journal of Advanced Research and Reviews, 26 (1). pp. 431-449. ISSN 2581-9615

This article presents a comprehensive case study of implementing a data mesh architecture for a global enterprise facing challenges in managing and deriving value from exponentially growing data assets. The organization's journey from traditional centralized data architectures to a decentralized data mesh model demonstrates how domain-oriented ownership, treating data as a product, self-service infrastructure, and federated governance can transform an enterprise's data ecosystem. Through detailed industry-specific applications across financial services, healthcare, retail, and telecommunications, the article illustrates how these principles deliver consistent benefits regardless of sector. The implementation addressed both cultural and technical challenges through systematic problem resolution frameworks, while achieving substantial improvements in data latency, quality, and business value. Economic considerations reveal that while initial investment is higher than centralized approaches, data mesh demonstrates more linear cost scaling with predictable ROI timelines. The results include significant reductions in processing time, improved data consumption, decreased quality incidents, and tangible business benefits in supply chain optimization, regulatory compliance, customer experience, and product development. The article offers a practical blueprint for organizations seeking to modernize their data infrastructure to support more agile, responsive, and value-driven data initiatives at a global scale.
