To continuously deliver IT systems at speed with a focus on business value, high-performance IT delivery teams integrate quality engineering in their way of working.

Quality engineering is the new concept in achieving the right quality of IT systems. Testing only after an IT product was developed is an outdated approach. Built-in quality from the start is needed to guarantee business value in today’s IT delivery models. Quality engineering is about changes in skills, organization, automation and quality measures.

Target Audience: All people involved in high-performance IT delivery teams
Prerequisites: General knowledge of IT delivery
Level: Advanced

Extended Abstract

To continuously deliver IT systems at speed with a focus on business value, high-performance cross-functional IT delivery teams integrate quality engineering in their way of working.

Quality engineering is the new concept in achieving the right quality of IT systems. Testing an application only after the digital product has been fully developed has long been a thing of the past. More is needed to guarantee the quality of applications that are delivered faster and more frequently in today’s high-performance IT delivery models. It is about achieving built-in quality. The road to quality engineering means changes in terms of starting points, skills, organization, automation and quality measures.

Our new VOICE model guides teams to align their activities with the business value that is pursued, and by measuring indicators, teams give the right information to stakeholders to establish their confidence that the IT delivery will actually result in business value for the customers.

Teams benefit from the clear definition of QA&Testing topics that are a useful grouping of all activities relevant to quality engineering. Organizing topics are relevant to align activities between teams and performing topics have a focus on the operational activities within a team.

Also, to be able to deliver quality at speed, for today’s teams it is crucial to benefit from automating activities, for example in a CI/CD pipeline, whereby people must remember that automation is not the goal but just a way to increase quality and speed.

In this presentation the audience will learn why a broad view on quality engineering is important and how quality engineering can be implemented to achieve the right quality of IT products, the IT delivery process and the people involved.

This presentation is based on our new book "Quality for DevOps teams" (ISBN 978-90-75414-89-9) which supports high-performance cross-functional teams in implementing quality in their DevOps culture, with practical examples, useful knowledge and some theoretical background.

In large software projects the assessment of the impact of a code change can be a cumbersome task. If the software has grown and shows an evolutionary design there are always unwanted side effects.

Change control boards are established. But on what data do they judge what can happen with the changes? Very often there is the HIPPO syndrome which means it is the highest paid person's opinion.

In this talk we will show you ways to come to a deterministic prediction of the impact, what data you need and what you can do with it.

On-Call is an increasing reality for developers, especially when a site has strict uptime requirements. And sadly, the experience often sucks. It's easy to mandate 24x7 support, it's much harder to set it up in a way that doesn't make the life of the people in the rotation miserable.
I want to talk about improving alerting. I'm focusing on creating high-quality alerts that trigger when they should and don't trigger when nothing is happening. Continuous tuning, automation, and using the right metrics are core parts of this process.

Target Audience: Developers, Architects, DevOps, Operators
Prerequisites: Monitoring, operating production software
Level: Advanced

Extended Abstract
Do you believe in “you build it, you run it”? What if you have on-call rotations, where you are responsible 24x7 for the health of a system? Nothing is quite so infuriating as a collection of poorly structured alerts that trigger randomly.
So, let’s do better! I want to talk about how to improve your monitoring capabilities. There are a few topics I want to touch:

• Reduce the noise
• Automate as much as possible
• Build actionable triggers
• Tune your monitoring constantly

After this talk, you’ll have concrete actions to make your engineers’ life easier when on-call.

Content Management Systeme, Web-Browser oder Betriebssystem: Viele der Produkte und Services die wir täglich nutzen werden mittlerweile als Open Source Projekte realisiert. Durch den hohen Einfluss, den die Open Source Entwicklung mittlerweile auf die digitale Welt hat, findet man allerdings auch viele unterschiedliche Aussagen über dieGefahren und Vorteile von Open Source Produkten. Vor allem wenn man sich selber noch nicht intensiv mit der Thematik auseinander setzen konnte ist es hierdurch schwer, fachlich korrekte Bewertungen zu Open Source Produkten treffen zu können.

Basierend auf der Mitarbeit an verschiedenen großen Projekten in der Eclipse Foundation und des Java Ökosystems werde ich in diesem Vortrag nicht nur die theoretische Definition von Open Source vorstellen, sondern auch zeigen, wie Open Source Projekte in der Praxis entstehen und weiterentwickelt werden. Wir werden uns auch anschauen, warumOrganisationen Software als Open Source veröffentlichen und welche neuen und interessanten Geschäftsmodelle sich hierbei ergeben. Hierbei werden auch die Themen wie Lizenzen, Security und Support von Open Source Produkten angesprochen, welche durch Beispiele wie OpenSSL und den 2014 veröffentlichten Heartbleed-Bug konkretisiert werden.

Das im Vortrag vermittelte Wissen soll helfen, Open Source Software besser verstehen und einschätzen zu können. Mit diesem Fachwissen können die verschiedenen Gefahren und Vorteile, die durch die Nutzung von Open Source Komponenten entstehen, in Zukunft besser beurteilt werden.

Due to the capabilities of Kubernetes, the usage of patterns rises to solve complex questions, but causing often confusion and unnecessary implementations. This talk intends to show what are the right scenarios for and for which cases another pattern is more suitable.
In this talk, Max will introduce you to various patterns, often misused by running applications and services within Kubernetes. The focus will be on structural patterns like Sidecars and Ambassadors as well as more advanced patterns like Controller and Operator.

Target Audience: Architects, DevOps Engineers, Platform Teams
Prerequisites: Good Understanding of Kubernetes
Level: Basic

Additional Information:
From this talk, you should take away in which scenario a pattern will suit most likely and how you can implement it. We will also look critically at the usage of these patterns.

The clean code principles are well-known in modern, agile software development. But what has become the default for our business code, unfortunately by no means applies to our infrastructure code. Instead, we find badly crafted, complicated and highly tangled code that is manually tested using a trial and error approach. However, for modern cloud based systems the infrastructure code plays a crucial role. So it's about time we begin to treat it as a 1st class citizen! This hands-on session shows how to craft clean infrastructure as code.

Target Audience: Architects, Developers, DevOps Engineers, SREs
Prerequisites: Basic knowledge of infrastructure as code practices and tools

I will introduce two AWS services: CodeGuru and DevOps Guru.
CodeGuru Reviewer uses ML and automated reasoning to automatically identify critical issues, security vulnerabilities, and hard-to-find bugs during application development.
DevOps Guru analyzes data like application metrics, logs, events, and traces to establish baseline operational behavior and then uses ML to detect anomalies. It does this by having the ability to correlate and group metrics together to understand the relationships between those metrics, so it knows when to alert.

Target Audience: Developers, Architects, Decision Makers
Prerequisites: Basic understanding of the code quality metrics and observability

Extended Abstract
In this talk I will introduce two AWS services: CodeGuru and DevOps Guru.
Code reviews are one example and are important to improve software quality, software security, and increase knowledge transfer in the teams working with critical code bases. Amazon CodeGuru Reviewer uses ML and automated reasoning to automatically identify critical issues, security vulnerabilities, and hard-to-find bugs during application development. CodeGuru Reviewer also provides recommendations to developers on how to fix issues to improve code quality and dramatically reduce the time it takes to fix bugs before they reach customer-facing applications and result in a bad experience
Amazon DevOps Guru analyzes data like application metrics, logs, events, and traces to establish baseline operational behavior and then uses ML to detect anomalies. The service uses pre-trained ML models that are able to identify spikes in application requests. It does this by having the ability to correlate and group metrics together to understand the relationships between those metrics, so it knows when to alert and when not to.

This talk describes how to build and run a successful product development organization that delivers business value, not just features. I will cover what makes effective product development teams, how to structure, loosely couple, align and choreograph them, especially in larger organisations with up to 100 teams. Methods I will talk about include OKRs and Kanban Flight Levels. In this context I will also show when and how decentralised product teams can benefit from centralised platforms.

Target Audience: CTO, Manager, Decision Makers
