From Homogeneous Monolith to Heterogeneous Microservices Architecture

on YouTube ↗56m

" summary

Migrates a monolithic Rails backend into a heterogenous microservices stack with 150 services and a mix of Scala, Haskell, Rust, Go, Node and Ruby; builds an actor‑based websocket real‑time sync, a write layer that pushes mutations into message queues, and a bash/immutable‑image deploy system called Wake; stresses the system with the BaGenan simulator (millions of simulated users), cuts service footprints (e.g. from ~30 to 3 servers), runs on AWS spot instances and reports reliable launches and drastically lower costs.
