它是最流行且被广泛信任的 Python 框架。被用于构建 Instagram 等系统。

它与关系型数据库（如 MySQL、PostgreSQL）耦合相对紧密，因此若要以 NoSQL 数据库（如 Couchbase、MongoDB、Cassandra 等）作为主要存储引擎并不容易。

它最初用于在后端生成 HTML，而不是创建由现代前端（如 React、Vue.js、Angular）或与之通信的其他系统（如 <abbr title="Internet of Things - 物联网">IoT</abbr> 设备）使用的 API。

Fue creado para generar el HTML en el backend, no para crear APIs utilizadas por un frontend moderno (como React, Vue.js y Angular) o por otros sistemas (como dispositivos del <abbr title="Internet of Things - Internet de las cosas">IoT</abbr>) comunicándose con él.

Например, вы можете запустить **несколько контейнеров**: с базой данных, Python-приложением, веб-сервером с фронтендом на React и связать их через внутреннюю сеть.

Все системы управления контейнерами (такие как Docker или Kubernetes) имеют интегрированные возможности для такого сетевого взаимодействия.
