Event-driven Architecture
summary
Shows how to move from APIs to true event-driven systems using Amazon EventBridge, Lambda destinations for async success/failure routing, and schema discovery for SaaS integrations; recommends replacing many SNS topics with a single EventBridge bus (Lego migrates to that model) and notes Realtor uses API Gateway to process 800 million images per day. Covers orchestration with Step Functions (including Express workflows) and observability with AWS X‑Ray plus CloudWatch ServiceLens and the embedded metric format.
