Abstract: Cloud-native data platforms are transforming financial services by addressing industry-specific challenges while enabling innovation and operational efficiency. The evolution from legacy systems to integrated cloud platforms represents a fundamental shift in how financial institutions manage data across banking, insurance, and capital markets. Regulatory requirements and competitive pressures from fintech firms drive adoption, with cloud platforms offering consumption-based models aligning costs with usage patterns. Financial institutions face distinct challenges including data residency regulations, compliance mandates, and workload variability. Modern architectures featuring decoupled storage and compute, elasticity, open formats, and serverless operations address these challenges while supporting analytics and AI initiatives. Platform selection requires specialized evaluation frameworks considering security, compliance, and cost factors. Migration strategies must maintain regulatory compliance while managing organizational change. Operational excellence demands comprehensive security, fine-grained access controls, cross-platform governance, and cost optimization. Examples demonstrate transformative impact across investment banking, insurance, and asset management, highlighting performance engineering considerations for financial workloads.
