In the landscape of digital transformation, achieving seamless interoperability between distributed systems is paramount. Building on the concepts from the talk "Where DDD Meets Enterprise Application Integration," this interactive workshop dives into the practical application of Domain-Driven Design (DDD) principles to tackle real-world interoperability challenges.
Participants will engage with specific business scenarios from various domains, each presenting unique integration hurdles. Through these scenarios, you will explore how to leverage Domain Message Flow to address interoperability issues effectively.

The workshop introduces four essential Enterprise Application Integration (EAI) architectural styles to provide a toolkit for designing robust integration solutions. Participants will be guided to select the most suitable architectural approach for each scenario, considering the specific business context and constraints.

Key activities include:
- Trade-Off Analysis: Perform comparative assessments of architectural options, weighing their pros and cons relative to the scenario's requirements,
- Quality Attributes Focus: Each scenario will highlight one or two critical architectural characteristics " (e.g."Time to Market", extensibility, composability) of EAI, which will be introduced and discussed,
- Decision Justification: Articulate the reasoning behind architectural choices, fostering a deeper understanding of how to align technical decisions with business needs,

By the end of this workshop, you will have gained:
-A solid grasp of interoperability as a first-class citizen in architectural design,
-Practical experience in using DDD to determine appropriate coupling degrees between systems,
- Insights into selecting the right EAI architectural style to facilitate seamless integration,
- Awareness of common pitfalls through the exploration of an EAI antipattern,
