Jenseits Micro-Frontends: Der Frontend-Modulith
Jenseits Micro-Frontends: Der Frontend-Modulith

Micro-Frontends eigenen sich nicht in allen Szenarien! Diese Session stellt einen alternativen Ansatz vor: Frontend-Modulithen. Wir besprechen das Abbilden fachlicher Domänen, die Kategorisierung von Bibliotheken sowie Zugriffseinschränkungen zum Erzwingen entkoppelter Teilsysteme. Außerdem nutzen wir inkrementelle Builds und einen Build Cache zur drastischen Beschleunigung des CI-Prozesses. Am Ende wissen Sie, ob Frontend-Modulithen für Sie der richtige Ansatz sind und wie Sie Ihre Anwendungen damit aufbauen.

Zielpublikum: Architekt:innen, Entwickler:innen
Voraussetzungen: Grundlagenwissen zu JavaScript von Vorteil
Schwierigkeitsgrad: Fortgeschritten

Applications Instead of Libraries: Micro Frontends Implemented Through Module Federation
Applications Instead of Libraries: Micro Frontends Implemented Through Module Federation

Imagine you have an enterprise frontend monolith. Due to explosive growth, around 30 teams work on it, with about 100 different use cases. How do you keep this system scalable and consistent?
That's the question we faced inside Partner Home at Wayfair. I'm going to share our experience implementing a micro frontend architecture based on React to distribute shared concerns as long-lived applications. We used module federation, a new feature in Webpack 5.
I'll talk about the general architecture, plus an overview of our technical solution.

Target Audience: Architects, Developers
Prerequisites: English, Frontend Architecture, React
Level: Expert

Mario Fernandez develops software for a living, and then he goes home and continues thinking about software because he just can't get enough.
He is a full-stack engineer with infrastructure skills. He has led multiple agile delivery teams, being an individual contributor, driving architecture topics, and coaching and supporting other team members.
He believes in high-quality software and advocates for Continuous Delivery, Tes- Driven Development, and quick iteration. He writes and speaks about his experience regularly.

The Root of All Evil: Shared Mutable State and How to Get Rid of It
The Root of All Evil: Shared Mutable State and How to Get Rid of It

Software is often resistant to modernization efforts, no matter if it's about phasing out obsolete technologies, migration to the cloud, or establishing modern architecture. The culprit is usually a dependency or obsolete assumption that's too closely coupled to the codebase. But what's the underlying root cause of all that coupling? Often, it's shared, mutable, synchronous state. We will look at a real-world project, and we'll dig ourselves out of the hole it's dug itself into using refactoring, event sourcing, and functional programming.

Target Audience: Architects, Developers
Prerequisites: Some programming
Level: Basic

Extended Abstract:
As shared mutable state is the core paradigm of object-oriented programming, it tends to be ubiquitous in OO projects. How to avoid it then? The example has followed a familiar path: Convenient tooling allowed the project to get off the ground fast, but tied it to its underlying technologies. By the time support for those technologies has expired, coupling has gotten so strong that huge resources are expended on keeping things going "just one more day". If you've seen projects like this hit a wall, this talk is for you.

Michael Sperber is CEO of Active Group in Tübingen, Germany. Mike specializes in functional programming and has been an internationally recognized expert in the field: He has spoken at the top conferences in programming languages, authored many papers on the subject as well as several books. Moreover, he is an expert on teaching programming.

Writing less code with Serverless on AWS
Writing less code with Serverless on AWS

The purpose of Serverless is to focus on writing the code that delivers business value and offload undifferentiated heavy lifting to the Cloud providers or SaaS vendors. Today’s code quickly becomes tomorrow’s technical debt. The less you own, the better it is from the maintainability point of view. In this talk I will go through examples of the various Serverless architectures on AWS where you glue together different Serverless managed services, significantly reducing the amount of the code written to perform the task. Own less, build more!

Target Audience: Developers, Architects, Decision Makers
Prerequisites: Basic understanding of AWS Serverless Services
Level: Advanced

Development and Discovery in Large-Scale Organizations
Development and Discovery in Large-Scale Organizations

The idea of looking at your organization as a single coherent system is tempting, but is it realistic? If it isn't, what does that mean for software developers, and how can we make discoverable what we are developing? This talk looks at organizations as ecosystems rather than as systems, and asks what that difference means for software development. It all boils down to focusing on software as components implementing business capabilities, and how to best capture these capabilities and make them findable and useful as reusable components.

Target Audience: Developers, Architects, Project Leaders, API Strategists
Prerequisites: API Basics, Large-scale information systems
Level: Advanced

Erik Wilde works in the Axway Catalyst team and focuses on API strategy, API programs, and API platforms. His main goal is to make sure that organizations make the right decisions when it comes to using APIs as the foundation of their digital transformation initiatives. Erik has a Ph.D. from ETH Zurich, is the author of many articles, papers, and books, is a frequent speaker at global API events, and contributes to standardization activities to help improving the way how APIs are designed, managed, and used.
