The Polyglot Platform: How Zalando Manages Language Diversity
summary
Zalando runs a shift from a single Java monolith to an API‑first microservice platform (70+ deploy units), moves infrastructure to AWS, and standardises APIs with Swagger APIs and REST. Organisation changes split delivery and people leadership and introduce radical agility plus yearly hack weeks. Nearly 800 engineers support ~15 million customers across 15 countries; results after six–seven months show faster independent deployments, many open‑source repos (play‑swagger, connection, etc.), and measurable skill pathways via the tour of Mastery for rotations and upskilling.
