When Splitting Serverless Apps Earns Its Keep

Architectural boundaries often reflect deployment schedules rather than execution limits. On platforms like Modal, grouping web endpoints, background cron jobs, and heavy GPU workers into a single app provides atomic deployments without sharing containers, scaling budgets, or container images. Splitting these workloads into separate apps isolates blast radiuses and decouples release cadences, but it also trades type safety for cross-app lookup risks and version coordination. True decoupling depends on whether components actually ship on independent schedules.
