Healthcare organizations are increasingly using cloud-based real-world evidence (RWE) platforms to power clinical research, population health analytics, and AI-driven insights. However, building these systems on AWS introduces complex governance challenges around privacy, compliance, and multi-institution collaboration. This session explores how to architect data governance into healthcare analytics platforms on AWS, focusing on practical design patterns rather than policy theory. We examine how ethical data stewardship principles such as consent, accountability, and responsible data use, can be implemented using cloud-native controls and services. The presentation walks through key architectural considerations for secure RWE platforms on AWS, including role-based access control, auditability, data minimization, and encryption, and how these capabilities support compliance requirements such as HIPAA and GDPR. Attendees will learn how federated, multi-account AWS architectures enable collaboration across institutions while preserving local data ownership and control. We will also discuss privacy-preserving analytics patterns on AWS, including approaches that support federated learning, differential privacy, and secure computation to enable AI-driven insights without exposing raw patient data. Practical implementation trade-offs such as performance, scalability, and operational complexity will be highlighted using real-world platform scenarios. Attendees will leave with actionable AWS architecture patterns and governance strategies for building secure, compliant, and scalable real-world evidence platforms that unlock innovation while maintaining patient trust.

Francis Hutcheson (1694-1746) was a pivotal early figure of the Scottish Enlightenment, a movement which strongly embraced empiricism and concentrated on the study of human nature and the relationship of individuals and society. Born in Ireland to a line of Scottish Presbyterian ministers, Hutcheson was educated by dissenting Irish Presbyterians in Ulster before matriculating at the University of Glasgow, where he studied philosophy and theology. In 1719 he was licensed to preach in Ireland, but rather than adopting the more traditional views of his forefathers, he gravitated toward the tolerant and liberal “New Light” Presbyterianism. Instead of further pursuing the ministry for which he had trained, he put his efforts into founding a dissenting academy in Dublin—a successful venture that occupied him for the next ten years. While teaching in Dublin, he moved in intellectual circles, and it was there that he wrote the four early treatises—collected into two books, the *Inquiry* of 1725 and the *Essay* of 1728—that quickly established his reputation as a philosopher. On being appointed chair of moral philosophy at his alma mater, he left Ireland for Glasgow in 1729. Contemporaries described Hutcheson as a popular and animated professor—the first at Glasgow to deliver lectures in English rather than exclusively in Latin. His most famous student was Adam Smith (enrolled 1737-40). Hutcheson's influence on Scottish thinkers was considerable. With his emphasis on the primacy of feeling over reason in our moral perceptions, he inspired David Hume’s moral sentimentalism. His analysis of natural rights and property in the *Inquiry* (Treat. II Sect. VII) as well as in his later works directly influenced Smith. The Scottish school of common sense realism derived partly from Hutcheson's explication of moral sense theory. His influence also made its way to colonial America, where his works were included in college curricula beginning in the mid-1700s. John Adams and other signers of the Declaration of Independence are known to have read Hutcheson. In the *Inquiry*, he takes up Locke’s epistemology of sense perception and broadens it into a theory of the “internal senses”—faculties of perception as powerful as the commonly designated five external senses. Elaborating Lord Shaftesbury’s notion of a “moral sense” and the earl's analogy between beauty and virtue, Hutcheson divided his *Inquiry* into a discussion of the sense of beauty and of the paramount moral sense—both being internal senses which operate without depending on mediation by the will or reason. Like Shaftesbury and the philosopher Richard Cumberland, Hutcheson held a strong distaste for the Hobbesian worldview. In the vein of the former two, he promoted a vision of humans as naturally benevolent and innately interested in the welfare of others, maintaining that others’ good brings us no less pleasure than our own good. Notably, he also sowed the seeds of utilitarian thought with his phrase “the greatest happiness for the greatest numbers” (Treat. II Sect. III). **Main Reading** The reading below is available at the Online Library of Liberty: * The [Inquiry](https://oll.libertyfund.org/titles/leidhold-an-inquiry-into-the-original-of-our-ideas-of-beauty-and-virtue-1726-2004), comprising the first two of Hutcheson's four early treatises (we are reading the 1726, or 2nd edition, of the book): read the [Preface](https://oll.libertyfund.org/titles/leidhold-an-inquiry-into-the-original-of-our-ideas-of-beauty-and-virtue-1726-2004#lf1458_head_019) and Treat.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
