* Processing data:
    * For example, let's say you receive a file that must go through a slow process, you can return a response of "Accepted" (HTTP 202) and process the file in the background.

## Using `BackgroundTasks` { #using-backgroundtasks }

Isso ainda é verdade.

Então, para poder ter **vários processos** ao mesmo tempo, tem que haver um **único processo escutando em uma porta** que então transmite a comunicação para cada processo de trabalho de alguma forma.

Un contenedor está en ejecución mientras el **proceso principal** (comando o programa) esté en ejecución.

Un contenedor normalmente tiene un **proceso único**, pero también es posible iniciar subprocesos desde el proceso principal, y de esa manera tendrás **múltiples procesos** en el mismo contenedor.

Pero no es posible tener un contenedor en ejecución sin **al menos un proceso en ejecución**. Si el proceso principal se detiene, el contenedor se detiene.
