HOSTING / DEPLOY THE CODE
Application & Serverless Hosting Explained
Application platforms accept your code or container and run it within a supported environment. Serverless functions run bounded pieces of work on demand. Servers still exist; you manage less of their operation.
What You Are Buying
A platform-as-a-service (PaaS) may manage deployment, TLS, scaling and runtime updates. Container hosting runs packaged applications, but a container alone is not a complete platform. Serverless and edge runtimes impose specific execution, networking and storage limits. A managed database is another specialized service with its own connection, storage and recovery requirements.
When You Would Use It
- Publish an application when maintaining a full server is not the main task.
- Run event-driven work with short, well-defined requests.
- Use managed database operations when the available engine and restore features fit.
What You Still Manage
You still own application security, dependencies, secrets, permissions and data handling. Confirm who upgrades the runtime and how a breaking update is announced. Files written to an instance may be temporary; persistent data usually needs a designated storage service.
Privacy Considerations
Build logs, environment variables, error traces and integrations can expose information even when the application database is protected. Ask what telemetry the platform and its add-ons collect and whether sensitive payloads can be excluded. Confirm whether application content is reused for secondary purposes, including AI training, rather than assuming the answer from a “managed” label.

Consumption, Allowances & “Unlimited”
Look beyond invocation count. Runtime duration, CPU time, memory allocation, concurrency, build minutes, database connections and transfer may each matter. Included requests can have maximum duration and payload limits. Automatic scaling can protect responsiveness while increasing consumption charges.
Read the plan’s resource limits and acceptable-use policy together. Ask what happens at the threshold: an extra charge, reduced speed, rejected requests or suspension. Understand the billing language →
Questions to Ask Before Buying
- Which languages, packages, background tasks and network connections are supported?
- What happens when a request exceeds time, memory or payload limits?
- Is local storage persistent, and how are databases backed up?
- Can the application run elsewhere without a major rewrite?
The takeaway: Less server maintenance is useful, but runtime and billing limits still shape your application.
