There are thousands of ways we can shape the software systems we build and organise our teams around them. Yet there is no flowchart we can simply follow to find the optimal design. The products themselves are software systems which grow harder and harder to reason about as they scale and age.

In contrast to modern software architecture, which uses distributed microservices, organizations historically structured their applications in a pattern known as “monolithic.” ” A monolithic software application has a few properties that are important to understand. Dynamic applications with ephemeral services.

In Domain-Driven Design, a large system is decomposed into bounded contexts , which become natural boundaries in code as microservices and as teams in the organisation. The Bounded Context Design Canvas I designed this canvas based on the typical flow of strategic DDD workshops I run publicly and privately.

Traditional monolithic architectures are built around the concept of large applications that are self-contained, independent, and incorporate myriad capabilities. As developers move to microservice-centric designs, components are broken into independent services to be developed, deployed, and maintained separately. Faster performance.

Layers start to emerge and as a result, shipping new customer-facing features require changes that cut through multiple layers of the architecture. Subsequently, the problem of coordinating multiple teams arises, each with their own backlog and performance goals to achieve. These concepts also apply to distributed architectures.

The next step is to determine what Team Topology boundaries align to…what should Stream-aligned (and other) teams own?

First and foremost, being intentional about organisation design requires good and honest discussions about all possible option. In this model, software architecture and code ownership is a reflection of the organisational model.

How will you design the most effective architecture which supports short-term goals and long-term evolution? Another piece of design feedback is that we can’t replace the generic context with an off-the-shelf solution.
