 ## Introduction
 
-NGINX is a high‑performance, scalable, secure, and reliable web server and a reverse proxy. NGINX enables all the main web acceleration techniques for managing HTTP connections and traffic. For many years, NGINX capabilities such as [load balancing]({{< ref "nginx/admin-guide/load-balancer/http-load-balancer.md" >}}), [SSL termination]({{< relref "../security-controls/terminating-ssl-http.md" >}}), connection and request [policing]({{< relref "../security-controls/controlling-access-proxied-http.md" >}}), static [content offload]({{< relref "../web-server/serving-static-content.md" >}}), and [content caching]({{< ref "nginx/admin-guide/content-cache/content-caching.md" >}}) have helped NGINX users to build reliable and fast websites quickly and efficiently.

-NGINX can also act as a secure application gateway, offering a number of specialized built‑in interfaces to pass traffic from users to applications. In this regard, not only can NGINX proxy HTTP and HTTPS traffic to an HTTP‑enabled application container, it can also directly talk to most of the popular lightweight application servers and web frameworks via optimized app‑gateway interfaces implemented in modules like [FastCGI](https://nginx.org/en/docs/http/ngx_http_fastcgi_module.html), [Memcached](https://nginx.org/en/docs/http/ngx_http_memcached_module.html), [scgi](https://nginx.org/en/docs/http/ngx_http_scgi_module.html), and [uwsgi](https://nginx.org/en/docs/http/ngx_http_uwsgi_module.html).

-Most commonly used application containers have embedded external HTTP interfaces with some routing capabilities, but one important reason to use NGINX as an application gateway is that it provides an all‑in‑one solution for HTTP connection management, load balancing, content caching, and traffic security. The application backend sits securely behind NGINX for better scalability and performance. It is also very easy to cluster application instances behind NGINX to build highly available applications.

 ## About uWSGI and Django
 
-A few words about "specialized interfaces". As useful as it is, HTTP has never been optimized for modern, lightweight application‑deployment scenarios. In recent years, a number of standardized interfaces have evolved for use with various application frameworks and application containers. One of these interfaces is the Web Server Gateway Interface ([WSGI](http://wsgi.readthedocs.org/en/latest/)), an interface between a web server/proxy and Python‑based applications.

 One of the most commonly used application servers offering the [uwsgi](http://uwsgi-docs.readthedocs.org/en/latest/Protocol.html) protocol – its own implementation of the WSGI protocol – is the [uWSGI application server container](https://github.com/unbit/uwsgi).

 Lightweight, heterogeneous application environments are becoming an increasingly popular way of building and deploying modern web applications. Newer, standardized application interface protocols like uwsgi and FastCGI enable faster communication between users and applications.
 
-Using NGINX and NGINX Plus in front of an application container has become a common way to free applications from the burden of HTTP traffic management, and to protect the application from unexpected spikes of user traffic, malicious behavior, denial‑of‑service (DoS) attacks, and more. Unbundling real‑world, external HTTP traffic from the actual application allows the developer to fully focus on the application logic, and leave the web acceleration and fundamental HTTP traffic security tasks to NGINX or NGINX Plus.
