Modernizing an architecture usually take years. Even a decade or more is nothing out of the ordinary for large organizations who have accumulated legacy and heritage systems over long periods of time. As a result, there can be pressure to begin modernizing a part of the system that will have a clear business impact.

Another hurdle to decision making is when technology leaders feel that the skills needed to deliver big changes don’t exist within the organization like the lack of DDD, architecture, or cloud skills. Choosing where to focus is a balancing act: delivering new products, fixing legacy software, and improving engineering culture.

How do we break a large system into smaller, more manageable modular components? 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. Both a wide and deep knowledge of the business and domain is essential.

The microservices era has been good for software architecture. A domain service builds on the basic definition of a microservice: it’s a loosely-coupled, independently deployable element of software architecture which is owned by a single team. Domains are part of the logical architecture of a business.

The key to loose coupling is to understand how the system you are building is going to change, and minimising the cost of those changes. Is there any way it’s possible to predict the future so that our architecture can easily absorb the changes we need to make of it? It could be a microservice or a module within a monolith.
