About This Architecture

Multi-source AWS data ingestion architecture routes API and SFTP uploads through WAF and AWS Transfer Family into segregated S3 Bronze buckets. Client and API traffic enters a public DMZ protected by WAF, which forwards API requests to API Gateway and Lambda for processing, while SFTP clients connect directly to AWS Transfer Family for file uploads. Both ingestion paths write to dedicated S3 Bronze buckets—one for API payloads, one for SFTP files—with Lambda emitting metrics to CloudWatch for monitoring. This layered design (DMZ, private subnet, core) enforces least-privilege access, isolates ingestion logic, and enables audit trails for compliance-heavy data pipelines.

How do I design a secure AWS data ingestion pipeline that accepts both API and SFTP uploads?

This diagram shows a layered AWS ingestion architecture where API clients and SFTP clients connect through separate entry points—WAF and API Gateway for APIs, AWS Transfer Family for SFTP—both routing to Lambda and segregated S3 Bronze buckets. CloudWatch monitors the pipeline for compliance and troubleshooting.
