# Platform scheduling (Vercel cron vs container `setInterval`)

> Generated from `mcp/patterns.registry.json` — do not edit by hand; change the registry and run `bun run patterns:build`.

_Index card — the docs below are the canonical explanation; deep-tier pattern pages additionally carry invariants and emulation notes._

**Category:** Jobs & Scheduling · **Tier:** light · **Risk:** medium — touches deploy config (vercel.json crons) and background execution

Cadence is owned entirely by platform config — vercel.json crons hitting /api/cron/[job] on serverless, or a single flat setInterval scheduler on persistent containers — so the job registry itself never changes when switching hosts.

**When to use:** Use when a job must run on a schedule across more than one hosting target without duplicating scheduling logic per platform.
