Why this workshop?
Join us in this engaging workshop where we’ll dive deep into mainstream architecture styles currently employed in backend systems. We’ll explore Layers, Hexagonal Architecture, Onion, and Vertical Slice Architecture. To bring these concepts to life, we’ll refactor a sample Java application in each style, weighing the pros and cons along the way. We will also see how the features of modern frameworks can help simplify these architectures.
Rather than getting lost in language and framework specifics, we’ll focus on the correlation between these architectural guidelines and the fundamental design principles, keeping in mind the constraints of our system. This workshop is open to backend developers, tech leads, architects, or anyone interested in a lively and informative exploration of software architecture.
By the end of this workshop you will have:
Understanding:
the Dependency Inversion Principle and its role in concentric architectures
how to clarify logic through the Separation by Layers of Abstraction
the principles underpinning the Onion, Hexagonal, and Clean Architectures
the main challenges in breaking down a codebase into vertical slices.
Capabilities:
how to protect your core logic against API models to simplify it
extracting orchestration logic into Facades.
comparing and implementing strategies to decouple a monolith into subdomains
Who is it for?
developer with hands-on experience in software design
an architect or technical lead keen on discussing pivotal design decisions
an eager learner aiming to delve into the realm of software architecture
prior experience with multi-threaded code is desirable, but not mandatory
What will you learn?
Fundamentals
Domain Model Design
Dependency Inversion Principle
Orchestrating Logic
Clean Pragmatic Architecture
Vertical Slice Architecture
Command-Query Responsibility Segregation (CQRS)
Wrap-up: Main take-aways; Quiz & Debates
