About This Architecture

Event-driven publishing pipeline using Allesheh SNS triggering AWS Lambda to orchestrate content distribution across Appleseed Service, Video API, and Apple News Publisher within a three-tier VPC architecture. Data flows from SNS through Lambda into the Distribution Layer where Appleseed Service coordinates video processing and content routing to the Access Layer. Apple News Publisher persists metadata in PostgreSQL and syncs with Apple News API, demonstrating separation of concerns across Core, Distribution, and Access layers. This architecture decouples notification ingestion from downstream publishing workflows, enabling independent scaling and fault isolation. Fork this diagram on Diagrams.so to customize VPC CIDR blocks, add additional Lambda functions, or integrate alternative notification sources.

People also ask

How do I design an event-driven publishing pipeline on AWS that routes SNS notifications through Lambda to multiple downstream services?

This diagram shows a three-tier VPC architecture where Allesheh SNS triggers AWS Lambda in the Core Layer, which orchestrates Appleseed Service and Video API in the Distribution Layer, ultimately routing content to Apple News Publisher in the Access Layer. PostgreSQL stores publisher metadata while Apple News API receives final content, demonstrating decoupled, scalable event-driven design.
