Microservice-based architecture usage is growing, but most of the involved applications are monoliths then migrated to microservices. Although this approach has been considered the conventional wisdom, it is still unclear if an application based on microservices can be built from scratch or must start as a monolithic application to be broken into smaller blocks later in its lifecycle. More unconventional approaches, such as starting with microservices, are not sufficiently explored, and reported experiences lack to guide the entire process. Thus, the problem to be addressed in this work is how to start with microservices from scratch. A guide was proposed to allow obtaining successful microservices solutions in greenfield projects. Following the Technical Action Research method, this set of guidelines was used to implement a microservices-based application without migrations. The solution was evaluated using the Quantitative Evaluation Framework and the results were analyzed. The most important aspect for that type of architecture was accomplished, such as improved development organization, the quicker release of new features and fixes, lower cost on growing the system, and increased performance and resilience. The application of the guide resulted in a value of 74% for the global quality of the system using the mentioned framework, and a score of 76 by applying the Microservices Architecture Assessment Platform.
