As you saw in the previous chapter about [Deployment Concepts](concepts.md){.internal-link target=_blank}, there are multiple strategies you can use.

Here I'll show you how to use **Uvicorn** with **worker processes** using the `fastapi` command or the `uvicorn` command directly.

cloud** qui fait une partie du travail pour vous, ou encore d'autres options possibles.

Je vais vous montrer certains des principaux concepts que vous devriez probablement avoir à l'esprit lors du déploiement
d'une application **FastAPI** (bien que la plupart de ces concepts s'appliquent à tout autre type d'application web).
