Cats in the Data Center. Who's in favor? Do you think there are cushions in today's data centers? We answer: yes, and plenty! And they're not just for tired engineers and technicians, or even a cat (though where would a cat come from in a data center, right?). These cushions are responsible for fire safety in the building. Cloud4Y explains that […]
The infrastructure of a modern metropolis is built on Internet of Things devices: from cameras on the roads to large hydropower plants and hospitals. Hackers can turn any connected device into a bot and further use it to carry out DDoS attacks. The motives can vary widely: hackers may be paid by governments or corporations, or sometimes it's just criminals looking to have fun and make money. In […]
Some time ago, we faced the issue of cleaning tuples in Tarantool spaces. The cleaning needed to be initiated not when Tarantool was already running out of memory, but in advance and with a certain frequency. For this task, Tarantool has a module written in Lua called expirationd. After a short period of using this module, we realized it was not suitable for us: […]
The official position of the Program Committees of Highload++ and other IT conferences regarding the claims against Igor Sysoev and Maxim Konovalov. The attack on Igor Sysoev, an outstanding programmer and creator of Nginx, a product distributed under a free license, accessible to everyone for free use and for studying the source code, is a glaring act of aggression against the entire industry. We express our support for Igor, and we want […]

The most valuable things each person has are their life and the time allotted to them. Everyone manages these resources in their own way. There are no second chances, you cannot be born again, and you cannot turn the clock back. Igor Sysoev devoted nearly 20 years of his life to painstakingly working on creating what is arguably the best web server in existence for all of humanity. Igor […]
We are convinced that open source is one of the foundations for rapid technological advancement. Sometimes such solutions turn into businesses, but what’s important is that the efforts of enthusiasts and the code behind them can be utilized and improved by teams around the world. Anton Stepanenko, Development Director at Ozon: — We believe that Nginx is one of those projects that definitely […]

The founder of Nginx, Igor Sysoev, can be considered one of the most talented and valuable individuals in Russia, and if this can happen to him, it can happen to any of us. This article sparked a massive discussion in the comments. This discussion and reactions are about […]
According to Russian laws, any company that handles personal data of its users in Russia becomes a data operator, whether it wants to or not. This imposes a number of formal and procedural obligations on it that not every business can or wants to bear alone. As practice shows, it's completely reasonable not to want to, because this field of knowledge is still so new […]
For monitoring servers and services, we have long been using, and still successfully use, a combined solution based on Nagios and Munin. However, this combination has several drawbacks, which is why we, like many others, actively utilize Zabbix. In this article, we will discuss how to address performance issues with minimal effort as the number of metrics being collected increases […]
