How to build a social network on serverless

on YouTube ↗29m

" summary

Migrates a monolith to an event‑driven serverless backend using Kinesis streams, Lambda handlers and per‑service DynamoDB/Redis stores, reaching about 200 functions and boosting deployment cadence from 4–6 to 80–100 deployments/month. Replaces Mixpanel ($3,000/month) with BigQuery/Athena streaming for ad‑hoc analytics costing only cents, and implements fan‑out for timelines via Kinesis→Lambda→SNS→Redis with Step Functions for intra‑domain workflows and synchronous fallbacks where immediate consistency is required.
