### Load Balancer { #load-balancer }

When using containers, you would normally have some component **listening on the main port**. It could possibly be another container that is also a **TLS Termination Proxy** to handle **HTTPS** or some similar tool.

As this component would take the **load** of requests and distribute that among the workers in a (hopefully) **balanced** way, it is also commonly called a **Load Balancer**.

* worker processes: worker processes (do not translate to "procesos trabajadores" or "procesos de trabajo")
* worker: worker (do not translate to "trabajador")
* load balancer: load balancer (do not translate to "balanceador de carga")
* load balance: load balance (do not translate to "balancear carga")
* self hosting: self hosting (do not translate to "auto alojamiento")

* type hints: аннотации типов
* type annotations: аннотации типов
* context manager: менеджер контекста
* code base: кодовая база
* instantiate: создать экземпляр (avoid "инстанцировать")
* load balancer: балансировщик нагрузки
* load balance: балансировка нагрузки
* worker process: воркер-процесс (or `процесс воркера`)
* worker: воркер

### Un Load Balancer - Múltiples Contenedores Worker { #one-load-balancer-multiple-worker-containers }

### Load Balancer { #load-balancer }

Container'lar kullanırken, genellikle ana port'ta dinleyen bir bileşen olur. Bu, **HTTPS**'i ele almak için bir **TLS Termination Proxy** olan başka bir container da olabilir ya da benzeri bir araç olabilir.

Bu bileşen request'lerin **yükünü** alıp worker'lar arasında (umarım) **dengeli** şekilde dağıttığı için yaygın olarak **Load Balancer** diye de adlandırılır.

#### Por trás de um Proxy de Terminação TLS { #behind-a-tls-termination-proxy }

Se você está executando seu contêiner atrás de um Proxy de Terminação TLS (load balancer) como Nginx ou Traefik, adicione a opção `--proxy-headers`, isso fará com que o Uvicorn (pela CLI do FastAPI) confie nos cabeçalhos enviados por esse proxy, informando que o aplicativo está sendo executado atrás do HTTPS, etc.
