Schedule
EventBridge Scheduler runs daily at 5:00 PM Central.
AWS V1
One short path from source to screen
The architecture is deliberately bounded. Each service has one job, and the dashboard receives one stable data contract.
FRED
Six public Federal Reserve series are downloaded.
Forecast
One Lambda fits, backtests, and publishes the model.
S3
Raw, archived, and latest JSON remain versioned.
Dashboard
A read-only Function URL feeds the Amplify site.
Controls
Small access surface
The FRED key is encrypted in SSM Parameter Store. S3 blocks all public access. The API Lambda can read only the latest dashboard object, and CloudWatch alarms on pipeline failures.
What V1 intentionally leaves out
No database, Glue catalog, Athena queries, SageMaker endpoint, Step Functions workflow, or custom dependency layer. Those services would add operating surface without improving this forecast.
