Building Next-Generation Applications with EDA
summary
A serverless video pipeline is built and runs in production: S3 triggers EventBridge rules, Step Functions orchestrate validation and routing, Lambda handles short jobs and ECS on Fargate runs videos over 20 minutes, results land in DynamoDB and DLQs hold failures. Uses SQS FIFO deduplication and client-generated idempotency tokens stored in metadata so retries return the same result, because EventBridge needs idempotency token (it is not deduplicated natively). Power Tools libraries simplify idempotent reads/writes.
