AWS Data Exchange

AWS Data Exchange is a fully managed service that makes it easy to find, subscribe to, and use third-party datasets — such as market data, financial data, healthcare data, and more — directly within AWS, without needing complex integrations.

1. When to Use It

Use AWS Data Exchange when you need external datasets (not your own data) for purposes like:

  1. Market research
  2. Financial analysis
  3. Training machine learning models
  4. and you want the data delivered automatically to AWS services like Amazon S3.

2. Example (Simple)

A company building a stock market prediction app uses AWS Data Exchange to subscribe to live stock prices from a data provider. The data is automatically delivered to their S3 bucket for analysis.

3. Important Limitation

  1. AWS Data Exchange is designed for external data sharing (third-party data consumption).
  2. It is not meant for internal data sharing across multiple AWS accounts within the same organization.

For internal data lake sharing, prefer:

  1. AWS Lake Formation (secure sharing of internal data)
  2. S3 bucket policies and AWS Resource Access Manager (RAM) for fine-grained access control.
