Monoliths always pay their debts
summary
Starts with a working monolith for a toy “Moo” service and actually splits it into three running microservices without rewriting routes, using Fastify plugins for encapsulation, Fastify HTTP proxy as an API gateway, Elasticsearch for storage, bcrypt and hyperid for IDs, and JSON Schema for validation. Claims Fastify hits ~40k req/s versus Node core 43k and demonstrates a migration path under a hypothetical “1 billion users” load. Demos show duplicated entry points, removed cross‑dependencies, and live requests succeeding.
