Microservices are a popular and scalable way of developing software, but to fully utilize their potential, you need a good design that allows developer teams to work autonomously and deploy without stepping on each other’s toes. Thats where Domain-Driven Design for Microservices comes into play. In this article, well learn the basics of Domain-Driven Design, and two essential concepts for microservices architecture: Bounded Contexts (BC) and Context Maps. BC is essential for defining a precise vocabulary or ubiquitous language that developers and domain experts can use. And Context Maps allow for depicting and anticipating the need for communication channels and relationships that exist between various BCs. Domain-Driven Design for Microservices takes place in two phases: the strategic phase, where the BCs are identified and mapped out on a context map, and the tactical phase, where each BC is modeled according to its subdomains business rules. By the end of this article, you’ll have a better understanding of how DDD can improve your microservices architecture design engagement.
