UnitedHealth Group’s Optum gathers and delivers actionable data derived from hundreds of millions of patient encounters directly to healthcare organizations and service providers. To do this required building an innovative healthcare intelligence platform that enables them to monitor and load streaming feeds from hundreds of data sources.
Before the data lake: Optum did not have a cost-effective and scalable way to provide its healthcare customers with more timely information and insights to improve decision-making and facilitate data exploration.
With the data lake: The Zaloni Data Platform (ZDP) monitored and loaded 56 data sources, representing over 250 TB of raw data files, which was expected to quickly grow to more than 100 data sources. The data lake centralized data from all sources for democratized data access. Also, ZDP solved many challenges out of the box, including more streamlined data transformation, data preparation, data access, data quality checks and record-level security tagging.
Results: The data lake managed 500+ terabytes of raw data, monitored and loaded 100+ data sources for streaming feeds, and reduced IT costs.
