Objectives

  • Recognize the problems of layered architecture and be able to address them using ports & adapters and functional modularization
  • Implement clean and hexagonal architecture and differentiate between these architectural patterns
  • Be able to apply different modularization variants and mapping strategies for the clean and hexagonal architecture
  • Be able to specifically use design patterns to map relationships between domain-oriented building blocks
  • Be able to continuously test your architecture using architecture tests and apply the evolutionary architecture mindset

Curriculum

**Day 1

Software architecture as structure and methodology

Hexagonal Architecture

  • Implementation of business objects and specialist values according to the principle of the rich domain model

Domain-Driven Modularization

  • Modularization with domain modules using root entities
  • Structuring domain modules
  • Design patterns for relationships between domain modules
  • Coding exercise: Dependencies between domain modules

**Evolutionary architecture

  • Motivation for architecture discipline based on the Broken Window Theory
  • The mindset of evolutionary architecture
  • Fitness Functions for Clean and Hexagonal Architecture
  • Coding exercise: Clean Architecture Fitness Functions with ArchUnit

Audience

This training is aimed at software architects and developers who want to understand these architectural patterns and their application in everyday project work. Participants should have the following experience and knowledge:

  • More than 12 months of practical experience in software development in a team of medium to large software systems.
  • Knowledge and practical experience in at least one high-level programming language (Java will be used for the course examples)
  • Familiar with layered architecture, SOLID principles, design patterns, dependency injection and modularization concepts (modules, packages, namespaces)
  • Familiar with the creation of domain-oriented object models in Java or a comparable programming language

Description

This training helps you to recognize problems of layered architecture and provides you with a toolbox of exercises that you can use to implement clean and hexagonal architecture. After the training, you will be able to continuously test your architecture and apply the evolutionary architecture mindset.

‍

When expanding existing systems, we repeatedly stumble across rigid architectures that cannot be expanded or even grown systems that no longer allow any expansion that matches the architecture, as there is no longer any recognizable architecture. As a result, the underlying business model can no longer evolve. But how can we prevent this scenario? How can we implement an architecture in our software system that can withstand the evolution of the system?

‍

Both the Clean and the Hexagonal Architecture promise a clear separation of the functional domain from the infrastructural aspects. The core idea, the Ports and Adapters Pattern, is powerful and helps to realize technical, functional and organizational flexibility in the software architecture. Building on this, we will examine the Clean and Hexagonal Architectures in the context of Evolutionary Architecture and present implementation options for Fitness Functions for these architecture patterns.

‍

In the training “Evolutionary Software Architecture” we will talk about similarities, differences, benefits, trade-offs and pragmatic development approaches for these architecture patterns. Using a demo application in Java, we will analyze code examples together and implement them ourselves using a functional example. We will use the building blocks of tactical domain-driven design and learn how to implement them embedded in the clean architecture. You will be given access to the demo application with Spring Boot and Java and will have the opportunity to study the topic in more depth afterwards.

Frequently Asked Questions

What is the maximum number of participants in a training session?

For most training sessions, we limit the maximum number of participants to 12 per instructor. This allows us to ensure that you receive the best possible guidance.

Are meals provided during in-person training sessions?

Of course, we’ll take care of your meals during our in-person training sessions. We usually provide snacks twice a day and lunch. Drinks are also available.

Where can I find information about the training session I've already booked?

You can find all the information about your training in our socreatory Navigator. Here, in addition to useful links and information, you’ll find the specific location of the training for in-person sessions and the link to the video call for online sessions.

When and how will I receive my certificate of attendance after the training?

If you have attended at least 75% of the sessions, you will receive a certificate of attendance from us. You can download it from our socreatory Navigator a few days after the training.
