In this session we will walk through various techniques to significantly reduce the resource consumption of regular Spring Boot applications, including using Spring AOT for regular Spring apps, compiling Spring Boot apps to native images (using GraalVM), and using CRaC for instant startup (for scale-to-zero scenarios). We will compare the different approaches, discuss pros and cons for each technology, and share concrete numbers from real-world applications to give the audience an idea of what can be achieved using these technologies.
Target Audience: Developers, Architects
Prerequisites: Basic Spring Boot knowledge required

Martin Lippert is part of the Spring engineering team at VMware and leads the Spring tools engineering. In addition to that he focuses on sustainability and green software for several years now.
User-centred design is one of the default modes of teams working with software, but the consequences are often unsustainable in a densely networked world as we privilege users over all other stakeholders and systems. How might teams approach building products, services and organisations from a more sustainable standpoint than 'user-centricity'? This talk looks at how the techniques of game design, community development, platform operations and security practices can support a practice focused on hyperobjects for multi-centric design.
Target Audience: Leaders, Builders, Architects, Designers, Community Members
Prerequisites: No previous knowledge, only enthusiasm for systems, building things and design
The key feature of a 'tragedy' is when everybody does the right thing but it goes wrong anyway. The aim of this session will be to look at why user-centred design goes wrong even if everyone's intentions are pure. This talk (gently!) brings in ideas from feminism, design thinkers, political science and anthropology to focus on very practical, grounded approaches to sustainable design in software teams. We'll look at how building things and designing organisations that have increased levels of friction can improve users' experience and how 'seamless' design can lead to disempowerment. And we'll also draw on the speaker's practical experience of building products used by millions of citizens as part of the UK's digital transformation. By the end of the session we'll have a sense of what might replace the shallow seamlessness of 'user-centred' design — a multi-centric, transcendental design aimed at manufacturing enthusiastic consent.
Simon Edward Bostock is a product and design leader who's worked with software for 20+ years. His interests include how firms and brands incorporate new technologies, how work flows through organisations, EverythingOps and service topologies.
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
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.

When Eric Evans wrote the Blue Book, he could not have foreseen cloud computing, infrastructure as code, and managed services.
Many of his tactical DDD patterns seem inadequate and strangely misplaced in cloud native environments. Even microservices, strongly tied to bounded contexts, no longer seem inevitable, as the industry standard shifts to serverless, low-/no-code tools, and genAI.
How much of DDD is still relevant? Can the same heuristics guide us through a different landscape? A story about finding boundaries in a strange new world.
Target Audience: Architects, System Designers, Developers with intermediate experience
Prerequisites: No previous cloud skills required, but helpful
Tobias Goeschel started his career as a freelance web developer in the late 90s and has since worked on hundreds of projects of varying sizes and lengths - from a single person to multiple teams, from a few days to several years - and in many different roles: Consultant, crafter, coach, and... well, architect. He is a strong advocate of diversity and inclusion in the tech industry, and an active member of the European Software Crafters and Domain Driven Design communities.
Domain-driven Design (DDD) steht für eine Vielzahl an Techniken wie strategisches DDD, taktisches DDD und kollaborative Modellierung. Dieser Vortrag gibt einen Überblick über das DDD-Universum. Dabei stellt er nicht nur die verschiedenen Konzept vor. Er zeigt außerdem auch die jeweiligen Vor- und Nachteile der Praktiken auf und weist auf die typischen Fallstricke hin - und wie man sie vermeiden kann.
Zielpublikum: an Software-Architektur Interessierte
Voraussetzungen: Grundlegendes Verständnis von DDD

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
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.
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
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.

Hannes Mainusch - impulsiver nerd-manager.
Dinge, die mich inspirieren, sind innovative Technologien, Röhrenradios und Radfahren. Und ich freue mich, wenn die Menschen um mich herum und ich lernen, besser zu werden. Veränderung beinhaltet Scheitern und Lernen, organisatorische Veränderung beinhaltet die Schaffung einer Lernumgebung. Also versuche ich, offen für neue Herausforderungen zu bleiben und gleichzeitig einen tollen und empathischen Job im Change-Management zu machen.
In den letzten Jahren war ich im IT-Management und Consulting tätig. 2016 haben wir die commitment GmbH & Co. KG als Experiment radikaldemokratischer Unternehmensberatung gegründet.
Things that inspire Hannes Mainusch are innovative technologies, tube radios and cycling. And he get excited when people around him and learn to get better. Change involves failure and learning, organizational change involves creating a learning environment. So he tries to stay open for new challenges while performing a kickass and empathic and embracing job in change-management.
In recent years he has been in IT management and consulting. In 2016 we founded kommitment GmbH & Co. KG as an experiment in radical democratic management consultancy.
Optimizing workflows, systems, and processes has been my passion for over a decade now. Continuous Learning has been one of my core values for all of my professional career. And so has being empathetic with everybody up and down the chain of command.
If I’m not working with technology, you will probably find me in my kitchen, working on things that taste delicious, be it food, baked goods or coffee, i just love tasty delights.

High traffic during business hours, no traffic at night, weekends and vacations, multiple teams, and several staging environments - these characteristics of a typical enterprise application. Pay-as-you-go, "scale-to-zero" and managed services make serverless architectures appealing for enterprise applications.
On-premise, on the other hand, you get the maximum flexibility and full access to machines with less automation and so more plumbing.
I will compare both approaches with focus on architecture and answer your questions in real time.
Target Audience: Developers, Architects

Great engineers often use back-of-the-envelope calculations to estimate resources and costs. This practice is equally beneficial in Machine Learning Engineering, aiding in confirming the feasibility and value of an ML project. In my talk, I'll introduce a collaborative design toolkit for ML projects. It includes Machine Learning Canvas and MLOps Stack Canvas to identify ML use cases and perform initial prototyping, thus ensuring a business problem can be effectively solved within reasonable cost and resource parameters.
Target Audience: Architects, Developers, Project Leader, Data Scientist
Prerequisites: Basic knowledge in machine learning

She focuses on Machine Learning Operations (MLOps), Data Architectures like Data Mesh, and Domain-Driven Design. Larysa initiated the Women+ in Data and AI Summer Festival.
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
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.
