Data Mesh: Decentralizing Data Architecture for Scale and Agility
Data mesh architectures distribute data ownership and management across business domains, enabling scalable, self-serve analytics at enterprise scale.
Traditional centralized data architectures struggle to scale with organizational growth and complexity. Data mesh represents a paradigm shift toward decentralized data architecture where business domains own their data as products, enabling self-serve analytics while maintaining governance and quality standards.
