Infrastructure choice is really a workload-shape question
The question is rarely serverless versus containers in the abstract. The real question is what kind of workload the team is operating, how fast it changes, how predictable its load is, and what level of operational ownership the team can realistically sustain.
That is why infrastructure debates often become clearer when anchored to actual product contexts like the AppNavi Observability Platform or a modernization effort such as the Legacy Monorepo and Microservice Modernization project.
Serverless usually wins when
Workloads are event-driven or bursty.
The team values fast iteration and lower operational overhead.
Execution boundaries are naturally small and independently useful.
This often pairs well with the Cloud Architecture service and data or notification workflows.
Containers usually win when
Runtime control matters more than elastic simplicity.
Long-lived processes or custom execution environments are central to the product.
The team already has strong operational maturity and wants predictable infrastructure patterns.
Hybrid is often the real answer
Many teams get the best result from mixing both. Event ingestion, automation, and lightweight APIs can stay serverless, while steady workloads, special runtimes, or stateful execution patterns can live in containerized services.

Final takeaway
Infrastructure choices should serve workload reality, not team identity. The strongest platform decisions are usually the ones that match execution shape, cost profile, and operating maturity at the same time. If you need help making that call, reach out.
