+
+# Back-end customization
+
+Strapi runs an HTTP server based on [Koa](https://koajs.com/), a back end JavaScript framework.
+
+:::strapi What is Koa?
+If you are not familiar with the Koa back end framework, we highly recommend you to read the [Koa's documentation introduction](http://koajs.com/#introduction).
+:::
+
+Each part of Strapi's back end can be customized:
+
+- the [requests](/developer-docs/latest/development/backend-customization/requests-responses.md#requests) received by the Strapi server,
+
+- the [routes](/developer-docs/latest/development/backend-customization/routes.md) that handle the requests and trigger the execution of their controller handlers,
+<!-- TODO: remove this comment — this link won't work until merged with PR #450 -->
+
+- the [policies](/developer-docs/latest/development/backend-customization/policies.md) that can block access to a route,
+
+- the [middlewares](/developer-docs/latest/development/backend-customization/middlewares.md) that can control the request flow and the request before moving forward,
+<!-- TODO: remove this comment — this link won't work until merged with PR #455 -->
+
+- the [controllers](/developer-docs/latest/development/backend-customization/controllers.md) that execute code once a route has been reached,
+
+- the [services](/developer-docs/latest/development/backend-customization/services.md) that are used to build custom logic reusable by controllers,
+
+- the [models](/developer-docs/latest/development/backend-customization/models.md) that are a representation of the content data structure,
+
+- the [responses](/developer-docs/latest/development/backend-customization/requests-responses.md#responses) sent to the application that sent the request,
+
+- and the [webhooks](/developer-docs/latest/development/backend-customization/webhooks.md) that are used to notify other applications of events that occured.
