Fundamentals of Software Architecture

Service-based architecture is a hybrid of the microservices architecture style and is considered one of the most pragmatic architecture styles, mostly due to its architectural flexibility. Although service-based architecture is a distributed architecture, it doesn’t have the same level of complexity and cost as other distributed architectures, such as microservices or event-driven architecture, making it a very popular choice for many business-related applications. Topology The basic topology of service-based architecture follows a distributed macro layered structure consisting of a separately deployed user interface, separately deployed remote coarse-grained services, and a monolithic database.
