Serverless services let teams run selected workloads while a provider manages much of the underlying infrastructure. They can reduce some operational work, but cost, latency, limits and portability depend on the application.
A practical example
An occasional document-processing job may suit managed execution. A continuously busy or specialised workload may need a different arrangement. Model expected requests, runtime, storage and dependencies before comparing cost. Test the behaviour that matters to users, including startup delays and service limits. Managed infrastructure does not remove application responsibilities.
Serverless trade-offs to evaluate
| Focus | Practical approach | Check before proceeding |
|---|---|---|
| Operations | Use managed execution for suitable workloads. | Application security and data handling remain your responsibility. |
| Performance | Measure startup behaviour and execution limits. | Long-running or specialised workloads may need another model. |
| Cost | Model requests, runtime, storage and data movement. | Pay-per-use does not always mean a lower total bill. |
Does serverless mean there are no servers?
No. The provider manages the underlying infrastructure. Your team still owns application behaviour, appropriate access, data handling and the design of the service.
