Serverless for visual journalism at the bbc
0 likes41 views
This document summarizes the serverless visual journalism system used at the BBC. It consists of a React client, API Gateway for authentication and routing, Lambda functions running an Express server, and assets stored in S3. API Gateway handles authentication using AWS signed requests instead of the BBC's PKI client certificates. The development environment runs Express directly instead of through Lambda. Lessons included considering the development environment during design and using appropriate tooling.
