From Monolith to Multi-Cloud Microservices -- Snap's Infrastructure at Scale

Snap migrated from a Google App Engine monolith to 300+ Kubernetes-based microservices across AWS and Google Cloud, handling 10 million requests per second while cutting compute costs 65%. This module covers the service mesh architecture, Switchboard control plane, multi-cloud strategy, and open-source contributions like Valdi and Djinni -- providing the technical depth candidates need for system design rounds.
