Welcome to the Event
Opening Keynote: A Day in the Life of High Load IT
Peter Milne, Technology Architect at Adform
Light hearted description of the daily events and challenges experienced by an IT department. What happens when High Load meets DevOps, Development, Security, Product Management and Customer Service; and how High Load adds a different perspective to traditional enterprise IT shops.
Inner Source: practices of open source used internally
Bernardus Peters, Solutions Engineer at GitHub
In this session we will talk about how adopting open source principles helps organizations to improve code quality, ship earlier and more often, increase developer happiness and help to attract and retain talent.
We will first talk about what these principles are, then focus on how they can be beneficial to organizations and individual developers and finally we will discuss some next steps to adopt these principles.
What we’re learning about burnout and how a DevOps culture can help
Ken Mugrage, Technology Evangelist at ThoughtWorks
One of the most overlooked advantages of converting to a DevOps culture can be the reduction of stress. This could be due to “sharing the load” as a whole team, the feeling of joint ownership in solving a business problem, or many other things.
If you’re asked to support somebody else’s application without any insight to how it was built and what problems it’s trying to solve you’re likely to experience more than a little stress. The same is true if you’ve toiled away creating the perfect application only to see it deployed in a way that makes it unable to perform.
The combination of stress and burnout is perhaps the biggest health threat in our industry. In fact, recent research has found that burnout--and the related concept of ""vital exhaustion""--increases your risk of cardiovascular disease as much as body mass index, smoking and lipid levels. Unfortunately there are also well-known stories of burnout-related suicides in our industry, making this literally a life and death issue.
If that isn’t reason enough to address the issue, we also know from the State of DevOps survey that the #1 indicator of company success is job satisfaction.
In this talk Ken will go over some of the leading research in the area of burnout. We’ll talk about some of the more common causes of burnout as identified by clinical research and talk about how you can learn from organizations with solid DevOps cultural practices to help alleviate them.
Next Generation Config Mgmt
James Shubin, DevOps/Config mgmt. hacker at Red Hat
Next gen config management tool, and the specific problems this project solves.
Three of the main design features of the tool include:
* Parallel execution
* Event driven mechanism
* Distributed architecture
This talk will demo a prototype I've built that implements these ideas and which is written in golang. I will also show the automatic edge, automatic grouping and automatic elastic etcd clustering management features.
An introductory blog post on the subject is available here. Attendees are encouraged to read it before the talk if they are interested!
Is DevOps in banking possible?
Piotr Stapp, IT Expert at mBank
Field Notes of a Command Line Ninja
Rustam Mehmandarov, Leader of the Norwegian Java User Group - javaBin
Have you ever witnessed someone write fancy commands and perform magic from the console. Have you ever wished you could learn, or brush up on, those skills too? Maybe you want to be more effective at your everyday tasks, or need a new topic for the next family dinner?
Join us and learn some awesome command line ninja skills. You will be able to find something new no matter your level of experience. The audience will get a chance to show off their skills as well, and there will be small prizes to contributors. The black belt and a little surprise await you at the end of this talk.
You can bring your PC with you and hack-along! All you need is a PC or a Mac running OS of your choice - Windows, Linux, or Mac OS. Windows users are advised to have their cmd.exe ready, and to install Cygwin.
Project Management: from Stone Age to DevOps
Antonio Cobo, Agile Delivery Consultant
The DevOps movement is gradually changing IT organisations. Project managers are often forgotten on this change, but they also need to change. Are project managers ready for the DevOps change? In this talk we will cover the changes project managers are experiencing, first with Agile and now with DevOps.
Closing Keynote: The long sad history of microservices
Greg Young, Independent consultant and entrepreneur
In this talk we will look at the history of the concepts around microservices. We will also look at what has changed vs what has stayed the same, how have the architectural goals changed? What areas of learning are worth following and what is just a fad? What are the core concepts and what is cruft?

Scalable prediction as a service using apache spark and python scikit learn
Josef Habdank, Lead Data Scientist and Data Platform Architect at INFARE Solutions
Developing and deploying a scalable Prediction-as-a-Service platform on a very challanging task that many big data practitioners are struggling with. The holy grail of data science/prediction infrastructure is to train the prediction models in real time as the data is collected and streamed into the data center, and serving the prediction results in an on-demand fashion via a service. This can be achieved by using Apache Spark and Spark Streaming with Python Scikt Learn.
A Practical Introduction to Akka Streams (live coding session)
Jacek Kunicki, Senior Software Engineer at SoftwareMill
Stream processing is a hot topic today and it’s easy to get lost among all the possibilities. In this live coding session (in Scala) we will explore the Reactive Streams approach used by the Akka Streams project. On an almost real-life example, we’re going to walk through both the basics and some more advanced usages of the library.
Predicting the future relevance of research institutions - The winning solution of the KDD Cup 2016
Vlad Sandulescu, Data Scientist at Adform
I will present the winning solution to this year’s KDD Cup competition, part of the KDD conference, one of the largest academic conferences on data mining and machine learning. The challenge was to rank research institutions based on the number of accepted papers at academic conferences in 2016.
Competition participants were given a snapshot of the Microsoft Academic Graph dataset, a publicly available dataset organized as a heterogeneous graph which contains historical information about academic papers.
This talk will walk you through the entire thought process, including how we modeled the problem and systematically improved our predictions during the competition.
The Mathematics of Reliability
Avishai Ish-Shalom, Software Fairy at Wix.com
We often hear talks of “scale” and “reliability”, mostly based on personal experience and lessons learned. What can Mathematics tell us about reliability and scale? Can math help us scale our systems and companies?
It turns out that failure models, probability, statistics and other domains can help our analysis and provide insights.
It turns out that mathematics forces us to rigorously construct and analyse our models, often exposing subtle issues and misconceptions; But moreover, it allows us to expand our understanding and explore the consequences of scale and stress without actually building a system.
This talk will present simple failure models, explain the math behind common practices, show common misconceptions, introduce emergent system properties and showcase mathematical examples of why things behave differently at scale and how things that work well in small systems can be horrible at scale.
Adopting Neo4j at Enterprise scale
Dmitry Vrublevsky, Software Developer at Neueda
Jenkins as Code
Łukasz Szczęsny, Software Engineer at Uber
Jobs in Jenkins (or any other CI/CD tool) can be created and updated manually using UI. It is ok if you have a few/several of them. However, most of the companies grow and you can quickly wake up with dozens or hundreds of jobs to maintain.
A new email address/alias to get notification about failed builds?
Global migration to the better™ SCM? No way to do it manually with GUI in a convenient way. It just doesn’t scale. Manual scripts using Jenkins API? Better, but hard to test and maintain. The same applies to plugin installation, credentials managements etc. Luckily, there is a better way.
During the talk I will present how to create a scalable CI/CD solution using Jenkins with Job DSL and Jenkins Pipeline. Expect live demo - I will setup fully functional Jenkins instance with just one click!

Facts and myths about microservices
Maciej Aniserowicz, Developer & dev-trainer, blogger at devstyle.pl
Microservices is "the next big thing", which completely dominated IT discussions, blogs, magazines and conferences, and everything has already been told about it. How many facts and how many myths can you find in this sentence?
This talk will show what microservices really are. You will see, that they is the long-awaited ultimate solution which will cure IT all over the world. But.. is it a fact or rather a myth? Everyone should be interested in microservices. Fact of myth? Every team should delived projects as microservices! Is is a fact, or a myth?
Microservices solve a LOT of problems. Fact or myth? Also, microservices do NOT generate new issues. Fact or myth? Every single project should be done in this architecture! Fact or myth?
This is a good, refreshing talk. After ~40 minutes you will answer a question... is it a fact or a myth?
How to Win Black Friday – Practical advice on handling Peak Events
Simon Leigh, Solutions Engineer at Couchbase
With good selection of tools, technology and advanced planning, scaling your application for organic growth has now become manageable. However, the Digital Economy creates unprecedented peaks. New technology releases, “event” television live-streams and Black Friday shopping events all create peak loads that are orders of magnitude above baseline. In this talk we will discuss and explore what the engineers at Couchbase have learned from our field experience supporting customers that experience these dramatic loads. We will explain how you can apply the lessons we’ve learned to create highly available, resilient architectures that are built for peak events.
Stream processing as a service
Ernestas Vaiciukevičius, Senior Developer at Adform
Sometime age we started building Apache Storm based stream processing platform and offer it as a service for other teams in Adform.
Let's look how it went, what were the challenges and what's the end result.
A Practical Primer on Building Real-time Data-driven Products
Øyvind Løkling, Staff Software Engineer at Schibsted Media Group
There is a lot of buzz around stream data processing these days, new frameworks are appearing at high speed, and the web is full of tutorials on how to count words with different technologies. This presentation will describe how to go beyond a “Hello world” stream application and build a real-time data-driven product.
We will present architectural patterns, go through trade offs and considerations when deciding on technology and implementation strategy, describe how to put the pieces together, and how to evolve products over time.
Test strategies for data processing pipelines
Lars Albertsson, Independent Consultant
A good automated testing strategy is crucial for achieving good product development productivity, and for quickly launching new features with continuous deployment. Although there is high awareness in backend software development for the need of good test structures and disciplining, it is often added as an afterthought in data processing environments, resulting in slow code-test-debug cycles and long delays getting data-driven features out the door. The time it takes from deciding to collect a new type of data, adapting the data collection and data processing pipelines involved, to creating a feature based on the data is often measured in weeks or months.
This talk will present recommended patterns and corresponding anti-patterns for testing data processing pipelines. We will suggest technology and architecture to improve testability, both for batch and streaming processing pipelines. We will primarily focus on testing for the purpose of development productivity and product iteration speed, but briefly also cover data quality testing.
The Power of the Toolrooms
Dirk-Willem van Gulik, Founder of Apache Software Foundation
The industrialisation made Artisan processes scale, in no small part thanks to the invention of the toolroom. The backoffice where skilled engineers would produce the templates and machines that allowed factories to leverage a generalist workforce and operate at fast scale. History turns a full cycle as we learn how to scale on the Internet. Scale not just in terms of software, hardware and bandwidth; but also scale in terms of people, skills and the organisational capability. This talk will show how focusing on the toolroom and the processes to select and refine tools can help you scale; with practical (open source) examples from the real world.
