NGINX, pronounced “engine-ex”, is an open-source web server that also is used as a reverse proxy, HTTP cache, and load balancer. Nginx is a great alternative in cases for a site that gets large volumes of traffic and is running into performance/memory issues. A server running Nginx serves the faster while using less memory than Apache. Many companies are using NGINX, including Autodesk, Atlassian, Intuit, T-Mobile, GitLab, DuckDuckGo, Microsoft, IBM, Google, Adobe, Salesforce, VMWare, Xerox, LinkedIn, Cisco, Facebook, Target, Citrix Systems, Twitter, SELinuxComputing, Apple, and Intel.
