As organizations migrate legacy datasets to cloud-native architectures, the tension between Big Data analytics and data privacy regulations has reached a critical inflection point. With the full operationalization of India’s Digital Personal Data Protection (DPDP) Act in 2025 and the tightening of GDPR enforcement, the concept of "Data Sovereignty" has evolved from a legal footnote to a primary architectural constraint. This paper reviews the limitations of traditional "encryption-at-rest" standards in the face of these new laws. We analyze emerging solutions, specifically Confidential Computing (using hardware-based Trusted Execution Environments) and Federated Learning, which promise to decouple data processing from data visibility. Market analysis suggests the Confidential Computing sector alone will expand to over USD 14 billion by late 2025. We argue that the future of software engineering lies not in centralized data lakes, but in decentralized, privacy-preserving compute fabrics.
