Realtime Event Processing, Streaming and Subscription for React Native Using Cloud Services
summary
Concrete cookbook: use Cognito SRP authentication to avoid sending passwords, exchange tokens with federated identities to get AWS credentials (expire after one hour), front APIs with API Gateway + Lambda, store/stream media from S3/CloudFront, and run pub/sub over AWS IoT MQTT over WebSocket. Demo shows SMS confirm/registration, S3 video streaming and cross‑region real‑time messages (Portland → us‑east‑1) working end‑to‑end. Note platform limits: iOS background uploads hit ~30‑second OS window; Android uses a background service that resumes after crashes.
