# Implantar FastAPI em provedores de nuvem

Você pode usar praticamente **qualquer provedor de nuvem** para implantar seu aplicativo FastAPI.

Na maioria dos casos, os principais provedores de nuvem têm guias para implantar o FastAPI com eles.

/// info

The <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> package is automatically installed with **FastAPI** when you run the `pip install "fastapi[standard]"` command.

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.

from fastapi import FastAPI
from fastapi.middleware.gzip import GZipMiddleware

app = FastAPI()

app.add_middleware(GZipMiddleware, minimum_size=1000, compresslevel=5)


@app.get("/")
async def main():

`FastAPI` là một class kế thừa trực tiếp `Starlette`.

Bạn cũng có thể sử dụng tất cả <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> chức năng với `FastAPI`.

### Bước 2: Tạo một `FastAPI` "instance"

```Python hl_lines="3"
{!../../docs_src/first_steps/tutorial001.py!}
```

Biến `app` này là một "instance" của class `FastAPI`.

from fastapi import FastAPI
from fastapi.middleware.trustedhost import TrustedHostMiddleware

app = FastAPI()

app.add_middleware(
    TrustedHostMiddleware, allowed_hosts=["example.com", "*.example.com"]
)


@app.get("/")
async def main():
