From Legacy to Cloud – Mistakes You Don’t Want to Make Your Own
From Legacy to Cloud – Mistakes You Don’t Want to Make Your Own

Come and hear the story of a company that is on the journey from the old monolithic, on-premise, waterfall world to the new modular, agile, domain-driven, multi-tenant, cloud-based microservices world. The challenges come from different directions: both technical and organizational aspects have to be mastered. The domain has to be understood, so that the system can be structured right. The big bang has to be avoided.
In this talk we will look at how our “fictional” company has struggled with and finally overcome those challenges.

Target Audience: Architects, Developers, Project Leaders, Managers
Prerequisites: Programming Experience
Level: Advanced

Henning liebt Programmieren in hoher Qualität. Diese Leidenschaft lebt er als Coder, Coach und Consultant bei der WPS – Workplace Solutions aus. Dort hilft er Teams dabei, Ihre gewachsenen Monolithen zu strukturieren oder neue Systeme von Anfang an mit einer tragfähigen Architektur zu errichten. Häufig kommen dann Microservices oder Self-Contained Systems heraus. Henning ist Autor von »Domain Storytelling« (Addison-Wesley, 2022) und dem www.LeasingNinja.io sowie Übersetzer von »Domain-Driven Design kompakt« (dpunkt, 2017).

Macro and Micro Frontend Architectures in Angular
Macro and Micro Frontend Architectures in Angular

Microfrontends are a popular concept for development in an enterprise project, where a large number of teams want to work independently.
But what is the cost achieving run-time integration and independent framework versions?
JS frameworks intended to build SPAs have solved many problems like deep-linking between pages without reloading the application.
This talk will give you some real life experience which challenges are to be considered using different integration patterns, using webcomponents, module federation and "classic" libraries.

Target Audience: Architects, Developers, Project Managers
Prerequisites: Basic knowledge of Angular or other JS SPA Frameworks
Level: Advanced

Extended Abstract:
How often do project managers wish for a microfrontend architecture? Contrary to microservices in the backend, microfrontends are not always the recommended future choice.
You might have to solve a lot of problems, that have already been solved in frameworks like Angular or React.
If we start separating UI elements in encapsulated webcomponents, we risk a lot of effort re-creating capabilities like deeplinking (routing) or event handling across components.
Or: we need to add additional frameworks that solve the challenges of navigation, context transfer and layouting.
The talk provides an overview, what default architecture patterns Angular provides and how to mitigate problems that might come with classical architectures or a monorepo.
The talk will mention use cases, when the usage of microfrontends is feasible and recommended. It will also provide workarounds if a microfrontend architecture is needed.

Secure by Design – the Architect’s Guide to Security Design Principles
Secure by Design – the Architect’s Guide to Security Design Principles

Architecture work has to balance providing clear guidance for important decisions with empowering people to build their aspects of the system without interference. In this session we'll explore how security principles can help achieve this for application security. The talk explains how principles can guide design decisions without being too prescriptive and explains a set of ten proven principles for designing secure systems, distilled from security engineering practice but presented in accessible language for the working software architect.

Target Audience: Architects, Developers, Testers, Project Managers
Prerequisites: Some experience in developing large scale systems
Level: Advanced

Extended Abstract:
Security is an ever more important topic for system designers. As our world becomes digital, today’s safely-hidden back office system is tomorrow’s public API, open to anyone on the Internet with a hacking tool and time on their hands. So the days of hoping that security is someone else’s problem are over.
The security community has developed a well understood set of principles used to build systems that are secure (or at least securable) by design, but this topic often isn’t included in the training of software developers, assuming that it’s only relevant to security specialists. Then when principles are explained, they are often shrouded in the jargon of the security engineering community and so mainstream developers struggle to understand and apply them.
In this talk, we will introduce a set of ten key, proven, principles for designing secure systems, distilled from the wisdom of the security engineering community. We’ll explain each principle the context of mainstream system design, rather than in the specialised language of security engineering, explaining how it is applied in practice to improve security.

Qualityland of Confusion
Qualityland of Confusion

Are you lost when folks talk about "quality" in the context of software? Just when you thought "high quality" means "good" and "QA" means "assure it's good", somebody hits you over the head with ISO 25010, where "quality" is just a neutral property of a software system. It's all a big happy pile of terminology quicksand where you sink faster the more you struggle for unambiguous and clear definitions. But we're here to help you out. We'll be looking at what's relevant about quality from a software architecture perspective.

Target Audience: Architects, Developers
Prerequisites: None
Level: Basic

Extended Abstract:
Among the prominent confusions is "quality requirements" vs. "functional requirements" - someone is sure to tell you that the first one is something not entirely unlike “non-functional” requirements. But if that distinction even is a thing, what's that "functional suitability" category of the ISO 25010 quality model? And where exactly do requirements even enter the picture? Once they do, how do we tell whether they are satisfied or not? And if they're not, how does all this terminology help with devising tactics for making things better? We'll separate out the taxonomy from the metrology, the metrology from the requirements, the functional from the non-functional (as far as this makes sense) and everything in between. We'll survey different ways of looking at quality and identify the murky areas where you need to be explicit about what you mean.

Enterprise Serverless Monoliths – Or Stay On-Premise
Enterprise Serverless Monoliths – Or Stay On-Premise

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.
