Framework
Fastify is a fast, low-overhead Node.js web framework with a hook-based request lifecycle and JSON-schema validation, also used as an HTTP adapter under NestJS.
AWS Lambda Web Functions run a Hono server without an adapter and allow 128 concurrent requests per environment, a dev.to guide says. Billing, concurrency and endpoint auth differ from Event Functions, so fit needs a check before a backend moves.
Reality
AWS Lambda now runs port-listening HTTP servers such as Express and Fastify, with up to 128 concurrent requests per environment. Billing moves to CPU time used, while memory is metered for the life of the environment.

ParkEase puts slot exclusivity in PostgreSQL 18, where no write path can skip it. The mechanism is a GiST exclusion constraint, and the cost lands on whichever booking request loses the race at insert time.
Reality
A Space Invaders build on AWS accepts kill events instead of scores and recomputes the total in a pure function. ECS Express Mode absorbs the ALB, certificate and DNS that choice drags along.

quayside shipped 1.0.0 with every mutant killed and 26 review findings triaged, then ran a payment twice on the dropped-connection retry it exists to prevent.
