Are you passionate about software architecture? Want to practice designing scalable, maintainable systems in a collaborative setting? Join us for an Architecture Kata, where we’ll tackle a real-world problem, discuss possible solutions, and refine our design skills together!
What’s an Architecture Kata?
An Architecture Kata is a hands-on, group exercise where participants work together to design the architecture for a given problem. It’s a great way to:
✅ Learn from others’ experiences and perspectives
✅ Improve your ability to think through architectural trade-offs
✅ Practice diagramming and communicating system designs
✅ Have fun while sharpening your skills!
Whether you’re a seasoned architect or just starting your journey in software design, this is a great opportunity to learn, share, and grow!
👉 RSVP now and bring your ideas to the table!
Got questions? Feel free to reach out. See you there! 🚀

The amount of business related data is growing tremendously. But how to get the most out of your data and obtain useful insights instead of only harvesting data and drowning in a data swamp? In this presentation I will provide an introduction in the various aspects of creating an end-to-end data warehouse solution in Azure Databricks. Emphasis will be on the place of the Databricks platform architecture inside Azure, the use of multiple external data sources, data organization strategies, cleaning and preparing data and security while working towards a live report in Power BI.

This introductory session is targeted towards software engineers who like to broaden their horizon and have an interest in data engineering related topics. No previous knowledge from the audience is required.

Talks:

Sjors Goering | Scaling multi-tenant apps with CosmosDB for PostgreSQL

Scaling your application layer is usually easy, simply spin up some extra containers, Azure Web App instances or Azure Function instances. However, your database does not scale with the same ease. In case you faced this situation, you might have chosen to store each tenant in its own database and host them in an Azure Elastic Pool. However, how do you execute cross-tenant queries, update the schema of thousands of databases, or maintain shared (non-tenant specific) data? Those and more questions will be covered in this session where you will see how easily you can build multi-tenant apps with Azure CosmosDB for PostgreSQL.

Sander ten Brinke | The best ways to use the latest OpenAPI features in .NET 9!

.NET 9 makes some impactful changes for creating .NET applications with OpenAPI support! In this session, we’ll dive into the breaking changes and latest OpenAPI advancements for .NET 9 and explore how these features can be leveraged to create robust, efficient, and well-documented APIs. We will cover both minimal API's and controllers.

This presentation will feature lots of demos with the aim of giving you an end-to-end experience of the latest and greatest features of OpenAPI in .NET 9!
