What is ?

HighLoad++ is the biggest Russian professional event for web developers of high performance systems. It becomes recognizable on a worldwide scale! We are happy to announce that this year, HighLoad++ Conference will happen for the 9th time and will be a host to more than 2500 participants. The event will take place in Moscow on November, 2 and 3.
Oleg Bunin

Oleg Bunin, standing among some of the most prominent IT specialists in Russia, inspires and organizes HighLoad++, HighLoad++ Junior, RIT, WhaleRider, FrontendConf, RootConf professional conferences and technological exhibitions on HighLoad++ and RIT.

Annually at HIghLoad++ we gather more than a thousand professional developers and experts of various areas of field from all around the world. In 2014 we hosted 1600 participants. This year we are expecting more than 2500 people at our event.

The program for this event is formed by the developers from biggest companies of Russian community and the world. Our program committee forms a set of specific standards for speakers, as well as chooses only the best topics among many of the submitted ones.

Potential topics

At the conference we cover all present-day valued topics for present and future high performance system developers.

We have vastly expanded list of covered topics this year and added six new sections.

After analyzing experiences and programs of past years we have added a few new fields to the event.

BigData and Machine Learning

New section dedicated to optimization of big quantities of data and machine learning.

  • Tools (Hadoop, Map-reduce, HBase…);
  • Reference systems, collaborative filtering;
  • Machine learning;
  • Data mining;
  • Pattern recognition;
  • Logging and monitoring;
  • Virtualization and containerization technologies;
  • Configuration management;
  • Continuous deployment;
  • Fault tolerance and disaster recovery.
Highly specific sections

Sections devoted to specific technologies and developments. Each year, these sections vary. In the last few years, they were:

  • Cloud Computing;
  • Video Streaming;
  • Search engines;
  • Billings construction;
  • RTB-systems.
Hardware maintenance

There is a whole lot of devices that make high performance systems easier to compose. We tend to study advanced hardware technology, hybrid devices and modern processors.


High performance systems do not require any specific measures of security. However in case of an attack, due to security system failure, the damage can be massive.

Front-end efficiency

It is a new experimental section, which is aiming to cover all the interactions between client and server based technologies, or sometimes completely on the client side. Many large-scale modern projects are running a whole programmed system with its own architecture, services and layers of abstractions in their browsers.

Databases and storage systems

Which databases are used in high performance engines and how? How large amounts of information are stored and managed? In the speakers section - database developers.

  • Databases optimization; replication, sharding, partitioning;
  • Cluster and network file systems;
  • Non-relational databases, NoSQL.
  • Designing scalable and fault-tolerant architectures;
  • Algorithms, queuing systems;
  • Programming languages: PHP, Perl, Java, Erlang, Ruby;
  • Technologies: BigIP, DSP‐programming, parallel computing;
  • Russian products: rapid web-servers, application‐servers, templates, monitoring systems;
  • Vertical and horizontal scaling;
  • Examples of working solutions;
  • Architectural patterns;
  • Queuing system.
  • Large-Scale project management features;
  • Highload project development;
  • Business management, recruitment;
  • Business processes of large-scale project making;
  • Highload system valuation.

Process organization for testing and their value in the production of high performance systems:

  • Testing: functional and stress;
  • Automated testing;
  • Split-testing.
System administration
  • Supporting, monitoring, deployment;
  • system administration; operational systems (Linux, Solaris, FreeBSD), operation systems tuning;
  • Hosting, DDOS attacks protection and organization;
  • Internet infrastructure: channel operators, channels;
  • Hardware, special equipment;
  • Loading balancing.
The Program Committee of the conference takes all possible efforts to make HighLoad++ a definitive tech conference. Experts working for the biggest and brightest companies of the IT industry (like Badoo, Mail.Ru Group, Yandex, Rambler, Nginx, etc.) form the program of HighLoad++ thoughtfully and thoroughly. They look for luminary talks focused on real, actionable technology solutions to high-scale problems.

We eagerly invite foreign speakers willing to introduce their talks to Russian-speaking audiences and graciously cover accommodation and airfare. Feel at home at HighLoad++, new ideas are always welcome! Indeed, up to one-third of our speakers come from abroad. We have already welcomed at our events some very prominent representatives of such IT companies as Google, Facebook, Yahoo, Microsoft, Percona, Etsy, Twitter and such media giants as BBC and Al Jazeera. We are greatly interested in “hot” talks from community members and contributors to the most meaningful Open Source projects — for instance, we eagerly keep in touch with the MySQL team, Cubrid team and PostgreSQL team, to name just a few.

We offer to our English-speaking guests both English-to-Russian and Russian-to-English simultaneous translation — so you can listen to some talks in Russian and be sure that the audience will understand your presentation. Please bear in mind that all talks in English are translated into Russian, but not all talks from Russian and CIS speakers are translated into English. We’re very proud of simultaneous translation at HighLoad++ and while it is still an experiment it provides excellent real-time access much of the Russian content to English speakers.

Foreign sponsors can contact the HighLoad++ Team in order to have booths, roll-ups or provide hand-outs and /or ads at the HighLoad++ event.

If you are interested in finding specialists from Russia and neighboring countries, you will be pleased to know that headhunting is also allowed at HighLoad++. Find more developers of high-loaded systems for your team at our conference!

Welcome to the next HighLoad++ and have an exciting professional experience!

They are respected experts of IT, very well-known in professional communities and working for top IT companies – such as Badoo, Mail.Ru Group, Yandex, Rambler, Nginx and many others. They understand the nature of high-load very well and have great practical experience.

The members of the Program Committee adore useful talks on technologies and solutions that can easily become your next-day practice at work. Marketing, sales and management are good – but they are inappropriate for HighLoad++.

What Our Speakers Say

Mark Callaghan
Small Data Engineer (Facebook)

You went out of your way to make me feel welcome and to make sure my stay was easy (arranging transfers, answering my SMS when I could not find my driver at DME, finding me during the conference when something had to be done, inviting me for social events). I would definitely do this again, but I can suggest a different speaker from Facebook next year who will do an excellent talk.

The conference was very impressive. My only regret is that I wasn't able to speak with more attendees because I have no Russian language skills.

Julio Capote
Scala developer (Twitter API team)
  • Translated Headsets: This was very useful in understanding other speakers.
  • Hotel: The hotel was very nice and comfortable, and also close to the subway. The breakfast in the morning was the best part.
  • Tours: Your tour of Arbat street and red square was a very nice gesture, thanks again.
  • Speaker selection: The selection of speakers was good and the talks were very interesting.
Joe Damato
Low level hacker (Computology, LLC & Sassano Systems, LLC)
  • The Russian to English translations were really useful and I am very glad the conference supplied those. Great addition.
  • I thought most of the speakers were really interesting and smart.
  • I had fun walking around the city and Red Square.
  • I thought that this year the conference was run much smoother than last year — you did a great job organizing and making sure people had taxis to pick them up and drop them off, which I really appreciated.
Alvaro Videla
Pivotal Inc., RabbitMQ top expert

The conference was really good.

Carlos Bueno
ex-Facebook, MemSQL

Translation service was very good. Hotel and travel arrangements were very good. The conference itself was full of fun smart people.

Marian Marinov
CEO at 1H Ltd.

I think that HighLoad++ gathers together a lot of smart people and manages to stay away from non-technical or sales related talks.
