# Luna Streams v.1.1.15 documentation

## Deploy

There are several options for sanic deployment:

- Standalone server

- Running a pool of backend servers behind of nginx, HAProxy or other reverse proxy server

Every method has own benefits and disadvantages.

Running sanic servers behind nginx makes several advantages:

- At first, nginx is the perfect frontend server. It may prevent many attacks based on malformed http protocol etc.

- Second, running several sanic instances behind nginx allows to utilize all CPU cores.

- Third, nginx serves static files much faster than built-in sanic static file support.

But this way requires more complex configuration.

Template configuration files for nginx are presented below. For more information, you can visit sanic.

## Configuration file for nginx

    upstream app {
        server 127.0.0.1:5161 fail_timeout=0;
        server 127.0.0.1:5162 fail_timeout=0;
    }

    server {
        listen 5160;
        client_max_body_size 4G;

        server_name 127.0.0.1;

        location / {
          proxy_set_header Host $http_host;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_redirect off;
          proxy_buffering off;
          proxy_pass http://app;

        }
    }
