Abstract

Microservice API design is a critical aspect in crafting a microservice architecture. While API design in general has been studied, the specific relation of API design to design practices and models commonly used in microservice architectures is yet understudied. In particular, practitioners frequently use Domain-Driven Design (DDD) in their microservice architecture and API designs. We thus decided to study existing Architectural Design Decisions (ADDs), their solutions options, their relations, and the decision drivers in these decisions. Using the Grounded Theory research method we studied grey literature sources. In this study, we identified six ADDs with 27 decision options, numerous relations between them, and 27 decision drivers. The decisions cover mapping domain models to APIs, defining API contracts in relation to domain models, designing API resources based on domain model elements, segregation of API resources, mapping domain model links to the API, and designing the operations of an API resource.

实践者对微服务api与领域驱动设计相互关系的看法:基于扎根理论的灰色文献研究

微服务API设计是构建微服务架构的一个关键方面。虽然一般的API设计已经被研究过，但API设计与微服务架构中常用的设计实践和模型之间的具体关系还没有得到充分的研究。特别是，从业者经常在他们的微服务架构和API设计中使用领域驱动设计(DDD)。因此，我们决定研究现有的架构设计决策(add)、它们的解决方案选项、它们的关系，以及这些决策中的决策驱动因素。运用扎根理论的研究方法，对灰色文献来源进行了研究。在本研究中，我们确定了具有27个决策选项的6个add，它们之间的众多关系和27个决策驱动因素。决策包括将域模型映射到API、定义与域模型相关的API契约、基于域模型元素设计API资源、分离API资源、将域模型链接映射到API，以及设计API资源的操作。
