Healthcare Data Lake on AWS Cloud to Enable Scalable Analytics and Research Access

About Client

The client is a global leader in advancing personalized oncology treatment and supporting cancer drug development research, headquartered in the Greater Boston Area, USA. The organization relies on large-scale clinical and research data to accelerate innovation, improve treatment outcomes, and support scientific discovery across regions.

Background

Data analytics is foundational to progress in the healthcare and life sciences industry, enabling improvements in clinical procedures, research quality, and decision-making at multiple organizational levels. 

As healthcare organizations generate vast volumes of data, challenges around storage, data management, and advanced analytics become increasingly complex. A modern healthcare data lake combined with analytics capabilities is essential to ensure data is accessible, well-governed, and usable by clinicians, researchers, and business teams alike.

Challenge

The client was managing large volumes of structured and unstructured data generated in multiple formats from a wide range of clinical devices. This environment introduced several challenges:

  • Difficulty cataloging raw clinical data and laboratory reports at scale.
  • Fragmented data storage that limited effective data management.
  • Inability to efficiently make data available to business applications and scientists for analytics and future research.

As data volumes increased, the absence of a centralized healthcare data lake constrained analytics adoption and slowed research workflows.

Our Solution

To address these challenges, a cloud-native healthcare data lake & analytics platform was designed using an AWS HealthLake architecture approach.

  • Business Scoping and Source Data Exploration was undertaken to define the solution and best possible support to meet the objectives of the enterprise.
  • The client required multi-geography data access for their work and hence, cloud-based data lake was found to be the ideal solution
  • A solution architecture was defined which included the data lake architecture as well as an analysis layer
  • A detailed scoring mechanism was applied to find the best cloud platform that fit the client’s requirement. Microsoft Azure, AWS, Hortonworks on AWS and Google were considered for the same.

Outcome

The final solution delivered a scalable and centralized healthcare data lake on AWS with integrated analytics capabilities:

  • Amazon S3 served as the foundational storage layer for the healthcare data lake, supporting both structured and unstructured clinical data.
  • An ETL framework built on AWS Glue enabled automated data discovery and metadata management through the AWS Glue Data Catalog.
  • Cataloged datasets became immediately searchable using Elasticsearch and accessible to business applications through SQL-based queries.
  • Amazon Redshift was implemented as the semantic and data warehouse layer, enabling efficient querying, reporting, and healthcare analytics at scale.

The implemented healthcare data lake & analytics platform provided a unified, searchable, and scalable data foundation. It significantly improved access to clinical and research data, supported advanced analytics, and enabled the client to accelerate oncology research and drug development using a robust AWS HealthLake architecture.
