As many of you may recall, the software design and architecture style known as service-oriented architecture (SOA) emerged in the mid 1990s. Since then, we have discovered better ways to build systems, including advances in cloud-based virtualization, continuous integration and delivery, and microservices. In the process, these technologies have made SOA and all the associated benefits a reality.
In November, I delved into explaining how microservices can be introduced into a large organization with well-established legacy systems. In this post, I cover domain-driven design (DDD) and how this development philosophy can be used to represent the real world in code while being well-suited to a microservices implementation.
