Igor Sysoev and the Evolution of nginx
The modern internet relies on the ability to handle millions of simultaneous connections without crashing. Much of this stability is owed to nginx, a high-performance web server that redefined how data is served across the globe. The story of nginx is inextricably linked to its creator, Igor Sysoev, whose journey from a small town in Kazakhstan to the helm of a global tech company is a testament to technical curiosity and the pursuit of efficiency.
Early Years and Technical Foundations
Igor Sysoev was born in a small town in Kazakhstan, then part of the USSR, to a Soviet military family. His family later relocated to Alma-Ata, where he spent his youth. His introduction to computing began at the local Pioneers Palace (a youth center), where he worked with Yamaha MSX computers. Like many early programmers, his first experiences were marked by the trial and error of debugging, recalling early struggles with simple syntax errors, such as confusing the letter "I" with the number "1".
After graduating high school in 1987, Sysoev sought entry into the MGTU im. Baumana technical university in Moscow. Although his first attempt was unsuccessful, he utilized the time to work at the lab of the Institute of Teacher Education under the USSR Ministry of Geology, where he began coding in BASIC on Iskra-2 PCs.
Between 1989 and 1990, Sysoev developed his first significant distributable software: an antivirus program. Written entirely in assembly code and spanning 100 KB, the program could detect several viruses prevalent in the USSR at the time, including Marijuana, Sophia, and Vienna. The software gained organic popularity and was even deployed in production plants. While users contributed virus variants to help improve the software, Sysoev eventually lost interest in updating the project by 1992.
Following his graduation in 1994, Sysoev spent nearly seven years as a system administrator for an oil company. After a brief tenure at the internet shop XXL.RU, he joined Rambler—one of Russia's leading web portals—on November 13, 2000.
The Genesis of nginx
At Rambler, Sysoev balanced his role as a system administrator with a passion for coding, often spending his spare time adapting Apache modules. By the fall of 2001, he identified a critical limitation in the Apache web server: it struggled to scale beyond 1,000 users on a single server. While adding more servers was a potential solution, it introduced its own set of complexities.
Driven by technical curiosity, Sysoev envisioned a more lightweight and performant web server that could handle scaling internally by increasing the number of possible connections. He began developing this original code in 2002. The core innovation was the ability to handle multiple users within a single running process, which significantly reduced the consumption of CPU and memory resources compared to Apache.
For the first two years, the project was a personal endeavor. It eventually gained traction when it was trialed at the music library Zvuki.ru. Other early adopters included the Estonian dating service Rate.ee and the Russian service Mamba.ru. Despite a total lack of formal promotion, the software grew through word-of-mouth and community support.
By 2006, an Austrian user began translating the documentation into English, opening the door to a global audience. By 2007, Netcraft statistics revealed that nginx had captured 4% of the global web server market, with a surprisingly strong presence in China.
From Open Source to Global Enterprise
Despite the software's success, Sysoev had little interest in marketing or sales. However, the potential of the project attracted investors. In 2010, he met Maxim Konovalov, who would become the company's co-founder. Later that year, meetings with Serguei Beloussov, a Singaporean IT entrepreneur, convinced Sysoev that the "market momentum" was right to transition the project into a commercial business.
The company was designed with international ambitions from the start. The Russian market was deemed too small and not yet ready for a paid support model, prompting the founders to establish an American office and hire a US-based director to navigate international sales.
The transition to a commercial model was gradual. In 2011, the company began exploring the sale of technical support for the open-source project. By 2013, while the subscription service NGINX Plus had not yet secured paying customers, the company formed a strategic alliance with Netflix. Together, they built a Content Delivery Network (CDN)—a system of distributed servers that deliver web content more quickly—based on FreeBSD and nginx, successfully scaling server traffic from 1 Gbit/s to 40 Gbit/s.
To professionalize their growth, the company hired Gus Robertson, a former vice-president of Red Hat, in 2013. The organization grew rapidly from a small team of 10–13 staff in 2013 to 250 employees by 2019, operating across Russia, the United States, Ireland, Singapore, and Australia.

Frequently Asked Questions
Why was nginx created instead of using Apache?
Igor Sysoev found that Apache lacked the scaling capability to handle more than 1,000 users on a single server. He wanted to create a more lightweight server that could increase the number of possible connections within a single server to improve efficiency.
What is the main technical difference between nginx and Apache?
The principal difference is that nginx can work with multiple users in a single running process, whereas Apache's architecture was more resource-intensive. This allows nginx to save significant amounts of memory and CPU resources.
How did nginx become popular globally?
The growth was organic. It started with a few Russian and Estonian clients, followed by a community-led English translation in 2006. By 2007, it had already captured 4% of the global market, particularly in China, without any formal marketing efforts.
What is NGINX Plus?
NGINX Plus is the commercial subscription version of the software that provides additional modules and professional technical support, contrasting with the free open-source version.
How did the partnership with Netflix benefit nginx?
The collaboration helped demonstrate the software's extreme scalability. By using FreeBSD and nginx, they were able to increase the traffic capacity of each CDN server from 1 Gbit/s to 40 Gbit/s.
