No, I don’t want to use your platform!
Engineering platforms promise to simplify workflows, accelerate delivery, and empower teams, but what happens when the very users they’re designed for actively resist adopting them? Beneath the frustration lies a powerful truth: platforms often fail because they’re built with good intentions but miss the mark on developer needs.
In this session, we’ll explore platform adoption from the user’s perspective, unpacking the key reasons why engineers might reject a platform. From rigid workflows and poor developer experience to a lack of trust or misaligned incentives, we’ll examine the real-world friction points that prevent success.
Attendees will gain practical insights into how to better understand user needs, foster collaboration between platform teams and developers, and make iterative improvements that address real-world challenges. This session will provide a view on building platforms that engineers genuinely find useful and want to adopt.
Life After Code: Developers in a Post-AI World
AI is already handling many development tasks, but while it’s not yet capable of fully replacing developers, it’s evolving quickly. What happens when AI takes over most software development? This session looks forward to the future of the developer role in a post-AI world.

Automating complex cloud test environments on demand at scale @ ASML
At ASML we build the most complex machine in the world. This machine also needs software to run and has a platform to communicate with the outside world. Next to hardware teams, we have hundreds of teams working on the software and we want to make their life easier in testing and qualifying their software for actual releases into the factories at customers where our machines run in production.
Managing these complex test environments can be a pain especially if you have to do this at the scale we operate on at ASML (Think thousands of devs and then thousands of VMs). In this session we’ll discuss some of the concepts of how we use the power of the cloud to dynamically spin up test clusters on demand at scale on multiple clouds meeting demands from both developers & our security department.
Join us to uncover the principles, strategies, and technologies that make it possible to automate and scale complex cloud test environments on demand. Discover how these advancements can empower your teams, streamline your operations even if you’re not working on the most complex machine in the world.
The AI Ensemble: Orchestrating AI Agents with .NET & Orleans
Building generative AI solutions can be split into 3 levels, starting with clever prompting to add some LLM magic to your application towards the second level where you add capabilities on your own data. The third level introduces the paradigm of connected agents - autonomous entities that communicate and collaborate to achieve complex goals.
This session will delve into the details of building AI applications at this advanced tier, utilising the robust capabilities of Microsoft .NET & Orleans. Microsoft Orleans, with its Actor model foundation, emerges as a particularly effective framework for orchestrating the interactions of these agents.

WORKSHOP: Build the distributed apps of the future using Dapr
Building distributed application is hard… As developers we want to focus on delivering business value with new features but there are so much things to also take care of on the side, especially in a distributed environment. Things as pub/sub, state management, bindings & triggers, service discovery, distributed tracing etc. Dapr tries to solve this problem by providing all of this to you so you can mix and match what pieces you want to use and also pick between many implementations of for example state management like cosmosDB, redis or dynamoDB
In this workshop you'll get hands on experience in building your own microservice based application using Dapr. You'll learn the following features of Dapr:
• State management
• Service discovery
• Actor framework
• Pub/sub
• Distributed Tracing
We'll be building the application using multiple programming languages, Docker & Kubernetes. Basic knowledge of Docker & Kubernetes is advised to get the most out of this workshop.
Building Microservice applications using .Net on Azure Container Apps
Kubernetes has all the hype but do you actually need all this complexity for your distributed application? There is a big trend happening by cloud providers to provide all the features Kubernetes brings without the complexity and Azure Container Apps is Microsofts take at this.
In this workshop you'll learn how you can build and deploy containerized applications using Azure Container apps from scratch using .Net.
It includes all the nice features it brings such as blue/green deployments, Dapr & autoscaling using Keda. Join this workshop to get ready to deploy your own microservice applications using Azure Container Apps
Azure Container Apps: The Future of Microservices in Azure
Kubernetes has all the hype but do you actually need all this complexity for your distributed application? There is a big trend happening by cloud providers to provide all the features Kubernetes brings without the complexity and Azure Container Apps is Microsofts take at this.
In this Session Geert will talk you through how you can build and deploy containerized applications using Azure Container apps from scratch including all the nice features it brings such as blue/green deployments & autoscaling. Join us to see if this can be the future of Microservices on Azure.
Azure cloud governance for DevOps organizations
Azure.. Often seen as just another layer of infrastructure where you can apply the same governance as you did for your on premises infrastructure.
In this session Geert will prove you that to use the full speed and agility of the cloud you'll require a completely different approach that embraces DevOps and autonomous teams. Does this mean it will be less secure? Join this session to find out why it doesn't have to be less secure and how to create a cloud environment that both DevOps teams and security officers will love.
Overcoming your fears as a developer
Being a software engineer can be a great job with often cool challenges that brings joy to many. But for many developers either junior or senior there are also many fears. Fear of not being good enough, Fear of not knowing everything about a new technology that your company just embraced, Fear of breaking production and gaining a bad reputation within the company and many other fears.
In this talk Geert will discuss these different fears with you, the developers to see how you can overcome these fears and things like imposter syndrome both from the developer side but also how you and your organisation can help your colleagues overcome their fears. Join us for tips and stories from junior to senior developers that should be relatable for your past, present or future.
Better architecture without architects
As a developer, have you ever had to implement an architecture thought up by an architect not in your team? Have you worked in an environment where you needed to propose changes in a CAB? Do you have architects in your organization who don't code? If you answer yes to any of the questions this session is for you!
In this session Geert will talk about how DevOps organizations with autonomous teams work faster and build better architecture without the need of enterprise architects or complex processes before decisions are made. Come discuss the future of architecture with us in this session. Architects & Developers are welcome!
Chaos Engineering: The fine art of breaking stuff in production on purpose
Have you ever been called out of bed because the high available system you run wasn't that high available as everyone thought? Or did you spend weekends doing manual fail over tests together with everyone in your team on standby?
These are things Chaos Engineering is trying to avoid. The idea of Chaos Engineering is that teams are in in control of their production environment. Being in control allows you to do experiments in production like killing servers, increase network latency or databases to see how your system is able to recover from it without impacting end users.
In this session we'll cover the basics of chaos engineering, practices of creating an architecture and system that allows for experimenting in production and how you can start doing this in your own environments.
A practical approach to Service Level Objectives
Service Level Objectives are a great way to embed quality & resilience into your software development lifecycle. But how do you start with this within your company?
In this session Geert will talk you through the why and what about Service Level Objectives (SLOs) & Service level Indicators (SLIs) and how you can start using them.
Come join this session to learn about making resilient & high available software products real & measurable!
