## Репликация — процессы и память { #replication-processes-and-memory }

В приложении FastAPI, используя серверную программу (например, команду `fastapi`, которая запускает Uvicorn), запуск в **одном процессе** уже позволяет обслуживать нескольких клиентов одновременно.

Но во многих случаях вы захотите одновременно запустить несколько процессов‑воркеров.

### Несколько процессов — Воркеры { #multiple-processes-workers }

## Реплікація - процеси та пам'ять { #replication-processes-and-memory }

У застосунку FastAPI, використовуючи серверну програму, як-от команду `fastapi`, що запускає Uvicorn, один запуск в **одному процесі** може обслуговувати кількох клієнтів рівночасно.

Але часто ви захочете запускати кілька процесів-працівників одночасно.

### Кілька процесів - працівники { #multiple-processes-workers }

Server’da, belirli bir **IP adresindeki** belirli bir **portu** dinleyen **yalnızca bir process** olabilir. Aynı IP adresinde başka portları dinleyen başka process’ler olabilir, ancak IP+port kombinasyonu başına yalnızca bir tane olur.

TLS (HTTPS) varsayılan olarak `443` portunu kullanır. Yani ihtiyaç duyacağımız port budur.

Bu portu yalnızca bir process dinleyebileceği için, bunu yapacak process **TLS Termination Proxy** olur.
