Nginx is releasing a commercial edition of its namesake open source Web server software, called Nginx Plus, which it will market as a software alternative to application delivery controllers (ADCs).
"The features that have been added are very similar to what you'd find in hardware-based ADCs," said Gus Robertson, CEO of Nginx. "We're an alternative to Apache, but I think we're also an alternative to hardware-based application delivery controllers."

Robertson said that the software will provide functionality similar to that of ADC appliances from F5 Networks or Citrix, which are used to speed delivery of high traffic websites through techniques of load balancing and caching.
Nginx has already made a name for itself as a Web server able to very efficiently handle large amounts of traffic.
Russian system administrator Igor Sysoev released the first version of Nginx in 2004 under a BSD open source license, after becoming frustrated by what he felt were the limitations of the market-leading Apache Web server software.
Sysoev specifically designed Nginx (pronounced "Engine X") for handling large volumes of traffic, up to 10,000 concurrent connections per server. It includes advanced traffic management features often found in ADCs, such as load balancing, edge caching and reverse proxy services.
According to the company, Nginx is now the most widely used Web server software among the world's 1,000 busiest sites. Web heavyweights such as Netflix, Hulu, Pinterest, AirBnB, WordPress.com, GitHub, SoundCloud, Zynga, Eventbrite and Zappos have all used Nginx to serve their sites.
The software now runs about 100 million websites overall, or about 14.55 percent of the Web, according to the latest Internet survey from Netcraft.
Sysoev founded Nginx the company in 2011, and took the role of chief technology officer. Nginx attracted US$3 million in first-round venture capital funding. Currently, it employs about 15 people. Robertson took over as CEO in April; formerly, he was the vice president of global business development for Red Hat, another open source software company.
Heretofore, Nginx, the company, has chiefly offered subscription support services for the open source software, around configuration and performance tuning, performance optimization and technical account management. Nginx Plus is the company's first commercial product.
Under a dual license, the commercial version of Nginx will offer additional features over the freely available open source version.
"The advanced functionality enhances the capabilities of Nginx in regards to load balancing, request routing, health monitoring and general control and monitoring of Nginx instances in mission critical environments," said Andrew Alexeev, Nginx co-founder and head of business development.
