Getting started with Event-Driven Architectures in 2023
summary
Claims that event driven architecture removes tight coupling by publishing state changes to a broker and that durability, replay and consumer-paced retries replace caller-side retry logic. Concrete tools and patterns shown include EventBridge, SQS and SNS, Amazon MQ, Kafka, Step Functions and serverless Lambdas. Demo builds a Unicorn Properties system, publishes contract events to rules that route to targets, and stores repos for Java .NET Python and TypeScript in a public Git repo. Scale example cites 100,000 items ordered per minute on Prime Day.
