About the conference
In short, Tech Internals Conf is about hardcore software engineering.
It is about technologies. A deep and thorough look into the internals of technological components, predominantly having software engineering focus, of how those components in fact operate and interwork with other components.

It is about technologies that can be used to build systems. Technology for the sake of technology makes little practical sense, and the overall complexities tend to lie in the intersections of different technological components, and not necessarily within isolated ones. Systems build out of components, but the whole is always greater than its parts, and it takes quite a lot more than just knowing the components themselves to build a system.

It is about stories of technologies that were used to build large scale and highload systems. TIC focuses on reflections back onto what has been done with fascinating technological components and systems built out of them. It is about large scale, highly loaded real world systems that we might use daily and take for granted without any consideration paid to the complexities that lie beneath. It is not about what could be done in theory, it is about what has been achieved and the pains and lessons learnt.

Compex IT systems. Highload. Performance engineering
5 key topics we focus on in our program
  • Architecture
    The end-to-end vision of products and services, and on a lower level an end-to-end view into the systems that produce and provide those products and services.

    • System Architecture & Scalability
    • Databases, Storage Systems, Big Data
    • Queues & Data Streams
    • Software Architecture & Design patterns
    • Microservices
    01
  • Development
    What it took to build a system or a component, with a detailed glimpse into internals of some particular technology area or some component.

    • Software Engineering
    • Best Coding Practices & Writing Maintainable Code
    • Machine Learning & Neural Networks
    • Video & Video Streaming
    • Quality Assurance & Testing
    02
  • Infrastructure
    Underlying hardware and software components behind a system running.

    • System Administration
    • Hardware Performance Optimization
    • Clouds & Datacenters
    • Networks, Internet, Connectivity
    • Internet of Things
    03
  • Operation
    What does it take to run a service? How could one spoil the brilliant product with a faulty operational practice? Or how could one sleep calmly at night while a fleet of systems keeps running flawlessly?

    • SRE & DevOps
    • Security & DevSecOps
    • Platform Engineering
    • Observability
    • Stress testing
    04
  • System design
    How were some systems or components built, why were design decisions made in a particular way, and what other options were considered and ultimately rejected? Success and failure stories of how some system-level components were designed.

    • Component Design and Sub-System Design
    • Performance Engineering
    • Low Level Programming
    • Managing Dependencies in Code
    05
Talk format
  • Your time slot will be 50 minutes, including 30-35 minutes for the talk and 10-15 minutes for the Q&A.
  • You can submit multiple proposals in any format: a talk, a workshop, a panel discussion, a lightning talk, etc.
  • Please make sure that your talk is relevant to our core audience - middle+ developers.
  • Your talk should be based on your real life experience.
  • We do not accept talks that have already been given and are publicly available.
  • TIC is vendor agnostic and does not promote a single supplier or a product line. It's not that a technology must be open source for it to be allowed in the programme, no — not everything needs to be publicly available, most of the interesting and useful developments are not and will not be open source, and talks disclosing intrinsic details on architecture and the workings of proprietary products are warmly welcome if they are technical and deep enough. However, outright proprietary product promotion is not allowed.
  • There is a slides template, you are requested to use at least the title slide.
  • Live demos are allowed if you inform us in advance.

The Conference (speakers are expected to be in Berlin on February 25)
How we work with speakers
1
Paper submission
We do not accept sales pitch style presentations. We are looking for people passionate about performance, who are able to speak effectively and from experience and who understand our audience of developers.

The program is designed by the developer community, representatives of large companies from around the world, and by tech developers and community activists. The selection of papers is multi-layered and complex — the Program Committee selects the best papers from the received applications unanimously according to several criteria.
2
Communication with program committee
A call with a member of the Program Committee may be scheduled if there are questions regarding your paper.
3
Competition and decision making
Program committee makes final decision by the stated deadline. Sometimes we might need more time due to high competition among submitted papers. The decision is primarily based on several criteria - applicability outside of speaker's context, up to date, uniqueness (the paper should not be already presented at previous conferences).

Each speaker will be contacted by program coordinator and informed on the final decision of the committee. For any questions prior or past that moment please feel free to contact us!
4
Developing your talk
A member of the PC will offer help with developing your talk and doing a dry run before the conference.
Speakers package
  • Conference ticket
    Speakers have full access to the talks and all conference activities: exhibition, networking zones, including free lunch.
  • Assistance with talk preparation
    Program committee members are experienced speakers themselves and are willing to share their expertise.
  • Networking
    Usually we organize pre-conference dinner for the speakers and the PC. We also have a dedicated room only for the speakers at the venue.
  • Feedback
    We collect feedback from our audience about your talk and share it with you.
  • Video and other materials
    Speakers will get an early access to all the materials of the conference.
  • Free ticket to any Tech Internals Conf next year
    All of the approved speakers may have a free ticket to any of our next year Tech Internals Conf.

Code of Conduct

Our conference is dedicated to providing a safe space for everyone, regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion (or lack thereof), or technology choices. We do not tolerate harassment of conference participants in any form. Sexual language and imagery is not appropriate for any conference venue, including talks, workshops, parties, Twitter and other social media. Conference participants violating these rules are subject to sanctions or expulsion from the conference without a refund at the discretion of the conference organizers.


The complete version can be found at http://confcodeofconduct.com/
The conference is purely technical — our visitors are well versed in the intricacies of programming, can form queries for databases and read execution plans for these queries, understand and apply various architectural patterns for the design of high-load projects with traffic of up to hundreds of thousands or millions of visitors per day.

We want to talk to speakers using the same language, so we don't expect evangelists, promoting specific companies or technologies. We highly welcome developers of these technologies or architects from these companies, from whom we can learn a lot. We don't care if you have 20,000 servers, but we would love to know how you deal with them in your operations. We are not interested in your 20 million visitors, but we are very curious as to which architectural solution allows you to withstand such a load.

We even recommend placing engineers (and not just salespeople) at company stands.

By the way, as part of the conference there will be a technological exhibition where many service providers, large companies, and technologies will be presented. At various points in time, our exhibitions have hosted Microsoft, Percona, Google, Badoo, Zabbix, and many international companies and communities.

To receive a commercial offer to participate in the exhibition, please write a letter and tell us about your proposition at partners@internals.tech.
