For each scenario, the guide explains how serverless platforms (Vercel, Cloudflare) handle it versus Railway's container approach, covering tradeoffs like cold starts, execution time limits, private networking, and memory constraints. Includes code examples for chunked processing, connection management, and queue-based background jobs with BullMQ. ## Full article daily.dev links to this article rather than hosting it.
