Nginx can be used to greatly enhance the performance of a website or application when used to serve static assets to the browser. This course demonstrates current issues with typical setups (for example, Apache) and compares performance with an Nginx setup, showing decreased load times and decreased server resource usage. The remainder of the course covers how to install and configure Nginx to perform the role of a reverse proxy, along with specific examples of common site infrastructure, such as a WordPress install, and how to configure Nginx for this type of setup.
