Integration and Conversation Patterns in SaaS Applications
summary
Argues that asynchronous integration improves availability and shows concrete implementations on AWS: SQS + Lambda for point‑to‑point buffering, EventBridge + Step Functions for event routing, DynamoDB and Cognito for control plane state, and three channel isolation models—shared, dedicated, sharded—mapped to cost and security tradeoffs. Recommends a two‑step onboarding—Sign up before subscribe—so an initial lightweight signup returns a token and a separate subscription flow provisions billing and tenant resources; demonstrates webhooks as HTTP callbacks for back‑channel notifications and reports these patterns work in customer deployments.
