Realtime Serverless Communication with

" summary

Claim: replace a brittle WebSocket stack (about seven Lambda functions, 600 lines of infra, 12-box architecture) with Momento Topics using HTTP API via EventBridge API Destination and gRPC routing so publishing requires no bespoke compute. Implementation uses Lambda, DynamoDB streams, OpenSearch, Step Functions; tokens are short‑lived and scope‑restricted. Demos include a QR-code browser-to-browser emoji feed, fantasy-football score deltas, feature-flag delta sync across containers, chat, and an E2E test hook for event-driven workflows — all working with low code and high fan‑out thanks to gRPC multiplexing.
