It's turtles all the way down

Room: Room 1 | Time: 09:00 | Duration: 90

Modularity might be the single most important concept in software design. But it goes way beyond software: modularity is a key concept in business, organizations, and even people. In this talk we will travel down many levels of modularity – from enterprises all the way to software methods. We will discuss interfaces, implementations, and the trade-offs of modularity. By the end of the talk, you will have a clear framework to consider modularity in all your systems.

Challenges of using Private AppSync for 1100 Parcel Lockers accross The Netherlands

Room: Room 1 | Time: 11:00 | Duration: 30

In 2024 and begin 2025 we’ve migrated the Embedded and Cloud application behind 1100 Parcel Locker Machines in The Netherlands at PostNL. Let me take you through the challenges and lessons we’ve learned replacing and migrating the cloud application where 1100+ (adding 500 more this year!) connect to. From why we had to do this, the mistakes we made, the lessons we’ve learned and improvements that are happening. Processing over 120.

Building a scalable ticketing platform

Room: Room 1 | Time: 13:00 | Duration: 60

Learn how we created a serverless, fault-tolerant, event-driven ticketing platform on AWS. We will cover the reasons behind the decision of building this platform from scratch ourselves, the architecture of the different components, the concepts of event logging and how we deal with security & privacy. The platform launched halfway 2024 and has already been battle tested by selling tickets for the biggest festival of The Netherlands, Zwarte Cross.

From 0 to 1 Million Events - EDA for the real world

Room: Room 1 | Time: 15:00 | Duration: 60

Event-Driven architectures are everywhere. Building them in a serverless, cloud-native way has never been easier. But many developers struggle with issues around type-safety, rule architecture, and scaling. In this talk, I’ll show you the best practices I’ve learned working with EventBridge and TypeScript in a startup handling over 1 million events a month. I first show you why we chose EventBridge, how to structure events, and why 5 targets per rule are not an issue.

Serverless vs Kubernetes: the final showdown

Room: Room 1 | Time: 16:00 | Duration: 60

There is no silver bullet!’—while true, that won’t stop us from stepping into the ring to argue over these two opinionated and polarising approaches to cloud computing. In this lively, no-holds-barred debate, we’ll spar over complexity, scalability, costs, and real-world use cases. Whether you’re Team Serverless, Team Kubernetes, or still undecided, join us as we wrestle with the tradeoffs that come with each model. Together, we’ll unpack the biases and prejudices we all bring to architecture decisions, challenge common assumptions, and dive into critical topics like security, legacy application modernization, and how each approach fits into event-driven architectures.
