Shopify vs Wayfair

Wayfair runs closer to the foundational model (Native (own / self-hosted weights)) than Shopify (Direct API). No shared foundational model — different bets.

Architecture

Shopify runs a modular monolith (primarily Ruby on Rails) deployed as multi-tenant pods, each with its own MySQL, Redis, and memcached, on Kubernetes clusters running on Google Kubernetes Engine, with Kafka-centric data pipelines for CDC, analytics, and event distribution.[1][10][11][14] Traffic is handled via a global edge (Anycast + nginx/OpenResty) feeding stateless app workers into these pods, enabling regional failover, blast-radius isolation, and large flash-sale scaling.[2][3][11][16]
