The Problem
Healthcare data organizations operate under some of the strictest regulatory constraints in any industry. Processing terabytes of patient records daily requires pipelines that are not just fast and reliable but fully HIPAA-compliant at every layer — data encrypted at rest and in transit, complete audit trails for every access event, strict access controls satisfying BAA obligations, and network isolation that prevents any patient data from touching the public internet. CyncHealth operates a health data exchange serving multiple healthcare organizations and needed an architecture that could ingest high-volume daily data from disparate sources, normalize and route it, and maintain the compliance posture that their role as a health information intermediary required. Existing approaches were reaching the limits of what a single-server deployment could handle. They needed a cloud-native solution that would scale with data volume without compromising the compliance controls that were non-negotiable for their business.
How We Solved It
We designed a multi-layer data pipeline where each component was chosen for a specific compliance and performance reason. AWS Glue handles ETL transformations across structured and semi-structured health data sources. Apache NiFi manages complex multi-source data routing with fine-grained provenance tracking — every record's movement through the pipeline is captured and auditable. Amazon Kinesis processes real-time health event streams with sub-second latency. Lambda handles serverless transformation tasks where compute needs are spiky and event-driven. Every S3 bucket is encrypted with SSE-KMS using customer-managed keys, meaning CyncHealth controls the encryption material. All service-to-service communication uses IAM roles with least-privilege policies scoped to exactly the resources each service needs. There are no hardcoded credentials anywhere in the stack. CloudTrail and CloudWatch Logs capture every API call and data access event, feeding into a centralized audit log store that satisfies HIPAA audit trail requirements. The entire environment lives in a private VPC with no public subnets. All communication with AWS managed services routes through VPC endpoints, so data never traverses the public internet.
