NGINX Vs NGINX Plus: Why Upgrade from Open Source to Commercial Version

NGINX open source load balancing software has gained much popularity over time for its reverse proxy, load balancer, and HTTP cache features. The NGINX open source is backed by immense community involvement, and hundreds of third-party modules have already been compiled in the open-source version.

Under the mission to create the best web server platform, NGINX recently came up with its commercial version, NGINX Plus. With the commercial version, NGINX further extends advanced features and the support of experts 24×7 via email.

With NGINX Plus, you get a one-stop solution for all your application delivery requirements, including content caching, web server, API management, etc. Also, NGINX Plus provides seamless delivery of advanced, web, and mobile-based applications.

What is NGINX Open Source?

NGINX open source is a high-performance free HTTP server that also acts as a POP3, IMAP, and reverse proxy server. It is a comprehensive solution for upgrades with zero downtime.

It’s known for its HTTP server capabilities along with the ability to serve as an email proxy server.

NGINX Open Source Features 

• Load balancer

  NGINX open source load balancer scales your application’s performance. With NGINX hosting, it is easier to improve your server’s efficiency, reliability, and performance.

• Reverse proxy

  NGINX servers use a reverse proxy to configure load balancing for HTTPS. In NGINX open source reverse proxy, the load balancer increases scalability, improves performance and reliability of web applications, and efficiently distributes traffic across application servers.

• High availability

  NGINX load balancing software provides resilience, scalability for your upstream application servers. Due to NGINX open source high availability, server also eliminates any single point of failure in the application stack. For any reason, if an NGINX server faces any issue, another server stays ready to take its place.

• Reverse sticky session

  NGINX open source reverse sticky session assigns a route to the client to pass a request to a server group. All requests are compared to identify the server to which the request is proxied.

• NGINX open source API gateway

  NGINX hosting is the most ubiquitous API gateway that processes API traffic in APIM solutions like those from IBM DataPower, Axway, Apigee, Kong, Torry Harris, and Red Hat 3 scale.

What is NGINX Plus?

NGINX Plus is a reverse proxy load balancing software with an added API gateway. The software helps in strengthening security controls, orchestrating Kubernetes containers, and ensures advanced monitoring.

With NGINX Plus, you can expect round-the-clock support from NGINX engineers and experts. Some of the advanced features of NGINX Plus over NGINX Open Source are active health checks, configuration through API, session persistence, and more.

NGINX Plus Features  

Some of the advanced features of NGINX Plus that make it an upgraded version of NGINX open source are:  

• Advanced load balancing capabilities

  NGINX Plus helps in scaling out and providing redundancies. As a high-performance load balancer, NGINX Plus enables session persistence, global server load balancing, active health checks, and dynamically reconfigures your infrastructure.

• Extended logging capabilities

  NGINX Plus offers extended logging capabilities that enable you to investigate performance issues with your applications. NGINX Plus provides a log analysis tool that is simple and cost-effective.

• Commercial‑grade activity monitoring

  NGINX Plus API supports commercial-grade live activity monitoring, including the dynamic configuration of upstream servers and key-value stores. The process has replaced the Upstream Conf module that was being used previously in NGINX Plus R13.

• High availability setup

  NGINX open-source uses routing software Keepalived 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.

• Application health check

  In case of a session timeout or communication error, the server responds with a status code to give a failed health check report. After this, the server is marked unhealthy, and NGINX Plus doesn’t send any client request to it unless it passes a health check again.

• Adaptive media streaming

  NGINX Plus is used to deliver MP4 and FLV content for HTTP pseudo-streaming. To further increase its competence, NGINX Plus supports multimedia streaming over computer networks for video-on-demand applications with Adobe HDS, Flash-based services, and Apple HLS.

• Dynamic on‑the‑fly reconfiguration

  The load balancing software is easy to reconfigure and doesn’t lead to any downtime or traffic loss. With NGINX Plus, you get additional features that help you further automate the process of modifying the configuration.
