The upstream module is one of the key components used to configure NGINX for proxying and load balancing. In this video, learn how to define the back-end servers that NGINX will be connecting to.
- [Instructor] Now that we've discussed…reverse proxies and load balancers,…lets take a look at how they're implemented.…The upstream module is one of the key components…used to configure NGINX for proxying and load balancing.…You can find more information on the upstream directive…in the documentation of NGINX.org.…Before we can set up a proxy or a load balancer in NGINX…we need to define the back end servers…that NGINX will be connecting to.…This is where the upstream directive comes into play.…If we consider NGINX's configuration…there are certain contexts where we can apply directives.…
We can apply them at the global context…that affects all of NGINX.…The http context for items that work with the http protocol…and inside the http context,…servers and location context for example,…that specifically configure virtual hosts…and the URI's used to access them.…Upstreams are defined in the http context.…This is useful so that one upstream can be defined…and then reused by multiple servers also defined…in the http context.…
