Serverless data ingestion at petabyte-scale with Amazon S3 presigned URLs

At AWS Community Day Poland we’ll show how we built a secure, serverless data ingestion service at petabyte scale. Powered by Amazon API Gateway, AWS Lambda, and Amazon S3 presigned URLs, our solution handles transfers of any size with enterprise-grade security, privacy, and full control over upload status.

Agenda

  1. Problem Statement & Requirements
  2. Evaluating Data Ingestion Solutions
  3. Amazon S3 Presigned URLs

Key topics

  • Multi-tenant petabyte-scale data ingestion — enterprise security requirements, terabyte daily uploads, and full file processing status control;
  • Architectural approaches — direct S3 access, Transfer Family, and API Gateway solutions with their trade-offs and limitations;
  • Presigned URL strategy — PUT vs POST methods, single-part vs multi-part uploads, and size constraints;
  • Serverless implementation — API Gateway with Lambda, security controls, and checksum validation for enterprise-grade data ingestion.
