People, Planet, Cloud and AI: Key Takeaways from QCon London
This year’s QCon London brought a wealth of talks directly or indirectly related to software architecture, ranging from the rise of AI to more established areas like anything cloud-related to the usual classics like architecture quality traits . The conference also featured many talks about sociotechnical aspects of software architecture and engineering and broadly considered sustainability.

Thoughtworks’ VP of Data and AI Shares Insights for Building a Robust Data Product at QCon London
During his QCon London presentation, Danilo Sato, vice president of data & AI at Thoughtworks, reemphasized the importance of using domain-driven design and Team Topologies principles when implementing data products. This ensures effective data encapsulation in a more complex landscape where data responsibilities are “shifting left” towards the developer.

Building a Platform to Gain an Unexpected Competitive Advantage: Ranbir Chawla at QCon London
During his QCon London presentation, Ranbir Chawla presented the journey his team took from moving from an “architectural perfect storm” and a highly manual operational system to a product company with a modern event-based architecture that can be released in < 1 hour. The company now focuses on providing real business outcomes to its stakeholders, and ensuring developers find joy in their work.

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.

Late Architecture with Functional Programming
Many approaches to software architecture assume that the architecture is planned at the beginning. Unfortunately, architecture planned in this way is hard to change later. Functional programming can help achieve loose coupling to the point that advance planning can be kept to a minimum, and architectural decisions can be changed later.

Domain-Driven Design with Value-Added Services and Domain Gateways at SoundCloud
Two articles were recently published to describe SoundCloud’s service architecture evolution towards implementing Domain Gateways, with a stop at Value-Added Services on the way. The authors describe how these Domain-Driven Design-based patterns helped reduce duplications and homogenise business and authorisation logic.

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.

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.
