What is self-hosting? Operating and maintaining your own model service
Explain self-hosting control and responsibilities through weights, dependencies and recovery, distinguishing it from local-only execution.
Understand the concept
Self-hosting means operating the service environment yourself, on owned hardware or managed cloud resources. It is not necessarily local or offline. Configuration control comes with dependencies, capacity and recovery. Suitability depends on tasks and maintenance capacity; starting a process is insufficient.
Serving requires coordinated models and deployment settings
vLLM serves inference and Kubernetes Deployments manage replicas and updates. Backends execute models while deployment systems manage instances. Check weight licenses and hardware; open-source server code does not grant every model license. Preserve reproducible configuration instead of one-off shell state. API compatibility does not guarantee identical outputs.
Check whether a clean environment can recreate the service
For public classification, rebuild a test service from saved settings and verify dependencies, readiness and outputs. Test instance recovery and duplicate prevention. No dependencies, weights or instances were installed here. Keep target-hardware behavior unverified until tested; another smaller model does not validate the target setup.
Upgrades and resource cleanup remain ongoing duties
Retain old images and model settings and replay samples before wider upgrades. Monitor resources and errors; no per-call fee does not mean zero cost. Include idle hardware, storage and recovery and assign ownership. Mix managed and self-run tasks with validated parameters and outputs. Deliver reproducible configuration and instructions, not only a currently reachable URL.
