Understand the boundary

Start by separating the public request boundary from background work and administrative control. A short lookup, a long report, and a deployment operation are different workloads even when all three use HTTP. Decide which responsibilities belong to a gateway, an application service, a queue, and a durable store. Keep the architecture small enough that the operating team can explain a failed request end to end.

A practical starting project

Map a report-generation request from acceptance to completion. Give the client a job identifier, define how status is read, and decide how output expires. Measure the compute, storage, logging, and network work caused by a single request. Compare a burst of short jobs with a steady stream of longer jobs before selecting a hosting pattern.

Where integrations go wrong

Serverless is not a synonym for free, unlimited, or maintenance-free. Managed services change the ownership boundary but do not remove authorization, cost review, or incident response. Avoid relying on one generic timeout across every dependency, and make the maximum permitted background work a deliberate product decision.
