It is known for its HTTP server capabilities along with the ability to act as an email proxy server.

Open source functionality of NGINX

  • Load balancerThe NGINX open source load balancer scales the performance of your application. With NGINX hosting, it's easier to improve your server's efficiency, reliability, and performance.
  • Reverse Proxy or Reverse ProxyNGINX servers use a reverse proxy to configure load balancing for HTTPS. In the NGINX open source reverse proxy, the load balancer increases scalability, improves the performance and reliability of web applications, and efficiently distributes traffic between application servers.
  • High availabilityNGINX load balancer software provides resiliency and scalability for upstream application servers. Thanks to NGINX's high open source availability, the server also eliminates every single point of failure in the application stack. For whatever reason, if one NGINX server faces a problem, another server stands ready to take its place.
  • Reverse sticky sessions
    La Reverse sticky sessions open source NGINX assigns a path to the client to pass a request to a group of servers. All requests are compared to identify the server to which the request is delegated.
  • NGINX open source API gatewayNGINX hosting is the most popular API gateway processing API traffic in APIM solutions such as those from IBM DataPower, Axway, Apigee, Kong, Torry Harris, and Red Hat 3 scale.

What is NGINX Plus?

NGINX Plus is reverse proxy load balancer software with an API gateway added. The software helps strengthen security controls, orchestrate Kubernetes containers, and provides advanced monitoring.

  • High availability configurationOpen-source NGINX uses Keepalived routing software to ensure high availability and prevent failover redundancy. With NGINX Plus, we can further extend this functionality with additional nodes and provide additional scalability and redundancy options.
  • Checking the status of the applicationIn the event of a session timeout or communication failure, the server responds with a status code to provide a failed status check report. Subsequently, the server is marked as unhealthy and NGINX Plus does not send any client requests unless it passes a health check again.
  • Adaptive multimedia streamingNGINX Plus is used to deliver MP4 and FLV content for HTTP pseudo-streaming. To further enhance its expertise, NGINX Plus supports multimedia streaming over computer networks for video on demand applications with Adobe HDS, Flash-based services and Apple HLS.
