As more organizations are moving to the cloud, cloud architectures are getting more sophisticated by having a kind of technology diversity. This includes for example container orchestrators, database services, networking components & virtual machines.
When it comes to security, observability on this diversity is paramount. The main question here is, do you really perceive when your app landscape is under attack?
In this session, you'll have the opportunity to see various attack vectors & ways to mitigate them using different technologies.
Target Audience: Architects, Developers, Software Engineers
Prerequisites: Basic cloud & security knowledge
Level: Advanced
Extended Abstract:
Come and watch a live attack on a real-world based cloud architecture and see the attacker scan web applications and start lateral movement with the goal of exfiltrating data. Furthermore, become a part of the blue-team, defending and securing the architecture with modern open source tools.

"Which programming language is the fastest" usually is everyone's first thought when green software is mentioned! It's a common deduction that the fastest code is, therefore, the most efficient, which then, of course, can save us from this climate disaster. However, code efficiency is not even half of the story! In this talk, Sarah will review the three approaches that make software green. She will also introduce efficiency-achieving practices that can take us closer to fighting this pesky climate change.
Target Audience: Architects, Developers, SRE/DevOps
Prerequisites: Basic knowledge of any Programming Language, Introductory Familiarity with DevOps Space
Level: Basic
Extended Abstract:
In this talk, I will go over the following:
- My journey so far with green software emphasizes how I don't need to leave my climate enthusiasm at home every day when I go to work
- Brief facts about WHY we need to take action now in the tech industry
- 3 approaches that make software green
- Why code efficiency is not the answer to most green software problems with an example
- Going over why DevOps practices are much more effective in achieving greenness in software with a couple of examples
- Wrapping up with fruit for thoughts, especially highlighting the close connection between DevOps practices and Green Software practices
- Encourage the audience to look at their software engineering problems through a green software lense

Data, the way that we process it and store it, is one of many important aspects of IT. Data is the lifeblood of our organizations, supporting real-time business processes and decision-making. For our DevOps strategy to be truly effective we must be able to safely and quickly evolve production databases, just as we safely and quickly evolve production code. Yet for many organizations their data sources prove to be less than trustworthy and their data-oriented development efforts little more than productivity sinkholes.
Target Audience: Developers, Data Engineers, DevOps Engineers
Prerequisites: Understanding of DevOps
Level: Advanced
Extended Abstract:
This presentation begins with a collection of agile principles for data professionals and of data principles for agile developers - the first step in working together is to understand and appreciate the priorities and strengths of the people that we work with. Our focus is on a collection of practices that enable development teams to easily and safely evolve and deploy databases. These techniques include agile data modeling, database refactoring, database regression testing, continuous database integration, and continuous database deployment. We also work through operational strategies required of production databases to support your DevOps strategy. If data sources aren’t an explicit part of your DevOps strategy then you’re not really doing DevOps, are you?

Organizations are drawn to migrate their systems into the cloud, but in practice, cloud transformations do not always succeed in achieving the advantages often promised by cloud providers, such as scalability, availability, and cost effectiveness.
We give an overview over Kevin Hoffmann's fifteen factors for cloud-native applications and how they help us achieve success in our cloud migrations.
Target Audience: Architects, Developers, Operations, DevOps
Prerequisites: Basic understanding of web services
Level: Basic
Extended Abstract:
You think you are already reaping the cloud's harvest by lifting and shifting your apps to some cloud-provided VM or container infrastructure?
You've already read about Heroku's (original) twelve factors, maybe even skimmed though Kevin Hoffmann's book, and think your app is good enough, because you are using Git, have a CI pipeline, and someone in the team once ran the app in a Docker container?
Or you think your team isn't going to the cloud any time soon and this advice does not apply to you anyway?
Maybe you're right. Chances are, you are in for a surprise, though.
The original twelve factors for cloud-native application development are (reasonably) well established and widely agreed upon. Yet, in practice, there appear to be some misunderstandings regarding their meaning, and we see cloud migrations fail precisely due to reasons that could be avoided by following these factors correctly. The extension to fifteen factors by Kevin Hoffmann is less widely known, but no less important for modern, cloud-native application landscapes, especially since this extension also revisits and updates the original twelve factors.
The goal of this talk is to disseminate and discuss the fifteen factors, as well as to emphasize their interrelations and embed them in the greater context of modern application development, in order to help reduce pain for many teams tasked with bringing their software to the cloud.
Matthias Dangl worked as a researcher in the field of software engineering at the SoSy-Lab at LMU Munich, and, since then, has accumulated several years of practical experience as a software architect and consultant.
"Σπεύδε βραδέως" in ancient Greek, or "festina lente" in Latin translates as "hurry slowly" an oxymoron saying to indicate the need for balancing deliberation and urgency.
In this talk we comment on the prevailing perceptions relating to speed of software development and how in a DevOps context what sometimes is perceived as fast from an individual's perspective has a deleterious effect on team performance while practices traditionally viewed by developers as cumbersome have in fact a positive effect on team performance and effectiveness.
Target Audience: Software Engineers and DevOps Practitioners
Prerequisites: None
Level: Advanced
Extended Abstract:
The talk draws on the experience of multiple projects but uses the team setup and 2020/2021 data of the NHS Covid19 app's backend services teams as a showcase for a team that managed to avoid neglecting subjects like peer reviews, documentation, testing etc. in a high pressure, high pace environment.
Vassilis Rizopoulos is Principal Devops Consultant at Zühlke specializing in team efficiency and automation. He has over 25 years of software development experience dealing with a wide area of subjects from embedded and regulated environments to web and cloud infrastructure.
He was one of the lead engineers responsible for developing, deploying and operating the backend services for the NHS Covid19 contact tracing app in 2020/2021.

At Tchibo we wanted to reduce our server and energy consumption with our product development teams. But why would we care? We all like fast snappy development and test systems. And our shop needs to survive Black Friday’s shopping traffic. Annual Google Cloud consumption forecasts do not trigger us to consume less. But when we started to show teams their related carbon dioxide footprint, we created a feedback loop that will help us to become better CO2-developers.
As developers, we have an impact - to program CO2 reduction.
Target Audience: Everyone, Developers, DevOps People
Prerequisites: None
Level: Advanced
Extended Abstract:
We will present the idea and first measurements on the server side. The planned client side measurements are still work in progress and very difficult to perform. Nevertheless is the client side induced CO2 consumption at large websites probably a large lever for reduction.

DevOps isn't dead yet and it will not die in the future. Platform engineering comes to leverage DevOps practices horizontally to support developers, operations and those in between. In this session, I will give you a perspective on how to move on from DevOps to Platform Engineering, how to design and shape your internal platform and build a vibrant community sharing best practices and enabling each other to overcome faster issues. In the end you will understand how we can reduce the cognitive load for dev teams to focus on features.
Target Audience: DevOps, Developer, Manager
Prerequisites: Experience in DevOps and an understanding of the pain of silos
Level: Advanced
Extended Abstract:
Platform Engineering is often seen as the evolution of DevOps. However, it is yet a new discipline using DevOps practices but focusing on the entire chain and breaking silos. I will show details from my experience on my job as well as 3 years of release engineering at Kubernetes where it wouldn't be possible to release without a proper platform.
