Virtual Domain-driven design

Language is a big topic in the Domain-Driven Design community. We want to have small bounded contexts, each with there own ubiquitous language. Having many ubiquitous languages means having a lot of translation between the bounded context. And having many translations means we can get lost. So what is the nuance between internal and external bounded context or services translation? Join us in a conversation with Julie Lerman, Indu Alagarsamy, Michael Plod and Nick Tune to talk about these nuances. We will talk about all the concept of dealing with these translations. From Anti-corruption, interchange, gateway, upcasting events plus the relationship patterns like the conformist, partnership and newer patterns.

It all started with a tweet by John Cutler . And it seemed that a lot of people from these communities learned a lot from each other. And we would love to learn more about different areas of overlap. It seems like goals and culture are aligned in both communities.

Feature branching is again gaining in popularity due to the rise of distributed version control systems. Although branch creation has become very easy, it comes with a specific cost. Long living branches break the flow of the software delivery process, impacting throughput and stability, but does it also affect the quality of our domain model? Join us with Thierry de Pauw in this Virtual DDD sessions to explore with us how feature branching can impact domain-driven design. Because one of the critical aspects of DDD is to keep gaining new insights together to create a rich and rigid domain model. For this, we need fast feedback which could be disabled by feature branching.

For the past decade and a half, Domain-Driven Design has been giving teams the tools to successfully tackle the complexity at the heart of software. But lots of people fail when they try to put its techniques and patterns into practise, especially at scale. Why? It can't just be because the Bluebook is so thick? We're going to argue that the "near enemies" of DDD are to blame. Things which look like DDD, but which are in fact counterfeits that push us farther away from our goal. Join us with Gayathri and Andrew who will tell the story of a large-scale DDD implementation that got complicated. They'll talk about how took stock of the situation as they found it, how they identified where the root problems lay, how they set everyone off on a course of success, and the mistakes we made along the way. Regardless of whether you are working with serverless, microservices or a more monolithic architecture (nothing wrong there!) - this fun talk is for those who want to learn the lessons of implementing DDD at scale, with a healthy dose of pitfalls and hazards to watch out for too

On twitter, a discussion started between Trond, Anton and Krisztina about working in agile product development without a clear business goal. Since twitter is a restricted medium to discuss these issues, we are taking it upon our VirtualDDD Meetup. Join us with Trond, Anton and Krisztina and let's have an honest discussion about what it means to work agile. What are the pros and cons? We dig into the underlying principles and philosophy of agile, diving into the practical instead of the theoretics of business agility. Do we need the business to be agile to do proper Domain-driven design, and what are the overlaps between agile and Domain-driven design?

Getting started or advancing your Domain-Driven Design knowledge on your own can be a frustrating experience. Especially when you have so many questions to ask and exciting domains to model. How do you then grow if there is no one in your company or area that shares your passion for DDD? During this Virtual DDD meetup Zsofia and Kacper will share their experiences in building communities in Hungary and London. They will discuss on topics such as finding speakers, venues, managing attendance and how to deal with no-shows. You will have an opportunity to join in and ask questions that we can crunch further. Let’s make it easier to start an own meetup group and try to figure out together how to grow as a domain modeller and meetup organiser.

Even with perfect naming and perfect code, it is hard to read the story of your domain straight out of it. You can be certain that you’ll have forgotten some of the nuances about the code the next time you see it. Or someone else sees it, because very few of us live our professional coding lives in an area where it’s only me ever handling the code. Someone is going to come back to your code - in five days, three months or five years. Luckily, if you write your tests the right way, they can tell the story of your domain in a way your production code can't. Let us show you how to create your tests so you can get rid of your stale documentation.

Thomas Ploch, an expert in the aggregate pattern, discusses its importance in software development. They explore the definition of aggregates, the challenges in ensuring consistency and security, and the evolution of aggregates in Domain-driven design. The conversation delves into managing interactions between aggregates, implementing aggregate roots, and comparing functional and object-oriented programming in DDD.

In the next SunDDDay discussion Alexey Zimarev and Marco Heimeshoff will join us and share their experience in building systems with CQRS and Event Sourcing. We will discuss what it exactly is, where it came from, what the strength and weaknesses are, when and how to use it, and how to design and maintain these systems. Join us through zoom webinar or follow the live youtube stream. You can interact with us and ask your questions through chat, or raise your hand in the zoom webinar and join us live to ask your questions fishbowl style!

Rebecca Wirfs-Brock, Paul Rayner en Alberto Brandolini will join us in this VDDD meetup and talk about what types of EventStorming there are, and what heuristics they use. Join us through youtube or zoom webinar in this discussion.
