Break Up the Monolith: Testing Microservices

on YouTube ↗43m

" summary

RetailMeNot breaks a PHP monolith into microservices (ledger, gift cards, mobile API, RMNQL) and replaces blocking analytics with an async pipeline (RabbitMQ/Kinesis), uses Swagger and Postman for API contracts and tests, and rolls out JWT auth across 13 services by rehearsing a deployment like theatre — a screenplay — with feature toggles so code lands in prod turned off. Nine dry runs handle 200,000 logins/day, produce zero defects, and drive the recommendation: push testing down the pyramid, use Selenium far less.
