Eric Evans Encourages DDD Practitioners to Experiment with LLMs
In his keynote presentation at Explore DDD 2024 in Denver, Colorado, Eric Evans, author of Domain-Driven Design, argued that software designers need to look for innovative ways to incorporate large language models. He encouraged conference attendees to start learning about LLMs and conducting experiments now, and sharing those results with the community.

Data Mesh Principles and Logical Architecture Defined
The concept of a data mesh provides new ways to address common problems around managing data at scale. Zhamak Dehghani has provided additional clarity around the four principles of a data mesh, with a corresponding logical architecture and organizational structure.

Evolving Architecture with DDD and Hypermedia: Einar Høst at DDD Europe
Hypermedia is an enabler for a better architecture, Einar Høst claimed in his presentation at the recent DDD Europe 2020 conference in Amsterdam. In his talk he described the architecture challenges at NRK TV, the TV streaming service at the Norwegian public broadcaster, and how they migrated their monolithic architecture into a more modular design and implemented hypermedia in their Player API.

Balancing Coupling in Distributed Systems: Vladik Khononov at DDD Europe
We have been told that coupling is bad, so we decouple everything and break everything apart into tiny services that can be changed independently. But by following this reasoning we often end up with a distributed mess, Vladik Khononov noted in his presentation at the recent DDD Europe 2020 conference in Amsterdam. Instead of fighting coupling, he proposes that we use it as a design tool.

Dissecting Bounded Contexts: Nick Tune at DDD Europe
There are many reasons for breaking up systems and making them more modular, Nick Tune noted in his keynote at the recent DDD Europe 2020 conference. We lower the cognitive load, teams can work independently, and from a business perspective we can do more granular investments. In his presentation, Tune discussed how by dissecting bounded contexts we can find more options when designing them.

How Serverless Impacts Design: Gojko Adzic at DDD Europe
Serverless architectures are becoming mainstream and can reduce both time to market and operational costs. But to benefit from them, applications must be designed around the constraints of this architecture style. At the recent DDD Europe 2020 conference, Gojko Adzic discussed his experience using serverless and how DDD and a serverless architecture will impact the design of an application.

Event Sourcing Done Right - Experience from the Trenches: Dennis Doomen at DDD Europe
Event sourcing is just a tool; it’s not a top level architecture style and should not be used everywhere, Dennis Doomen pointed out in his presentation on the Event Sourcing day at the DDD Europe 2020 Conference in Amsterdam where he shared some of the practices he has found useful when applying event sourcing to a problem.

The Distributed Data Mesh as a Solution to Centralized Data Monoliths
Instead of building large, centralized data platforms, corporations and data architects should create distributed data meshes.

Vlingo Joins the Reactive Foundation
Vlingo, creators of a platform designed to simplify building reactive systems using an actor model, has joined the Reactive Foundation. Launched in September, the Reactive Foundation was formed under the Linux Foundation to accelerate technologies for building the next generation of networked applications. Vlingo is a new charter member, joining Alibaba, Facebook, Lightbend, Netifi and Pivotal.

Sense and Nonsense in Event Thinking and Microservices
Modularity in the systems we are building is very important, but there are anti-modularity forces that we must deal with to be able to achieve this modularity. In a presentation at the recent Event-driven Microservices Conference, held by AxonIQ, Allard Buijze shared his thoughts and experience building systems based on DDD, CQRS, microservices and event sourcing.

Design and Implementation of a DDD-Based Modular Monolith
Kamil Grzybek recently published a project where he has designed, implemented, and in detail described a monolithic application with a Domain-Driven Design (DDD) approach. His goal is to show how a monolithic application can be designed and implemented in a modular way. He also discusses some architectural considerations and design patterns he has found useful in the application.

Eric Evans Wants to Improve the Language of DDD
Eric Evans wants architects to actively engage in improving the language used when modeling and designing complex systems. Some of the fundamental terms used in DDD, such as Bounded Contexts, are often misunderstood. Evans wants to see an active community try to address these concerns, with the goal that DDD "should be a real, living body of thought."

Migrating a Retail Monolith to Microservices: Sebastian Gauder at MicroXchg Berlin
In his presentation at MicroXchg in Berlin, Sebastian Gauder described how he and his teams migrated an existing food retail monolith at REWE, a large German company, into several business domains with 270 microservices, while increasing the number of teams from two up to 48. He also discussed the different design goals and rules they setup to make this possible.
