The goal of this work is to explore the distributed application architecture indicated by the caption Microservices, and in particular the deployment type named serverless. To make it possible the environment chosen to design, develop, deploy and test the components of such an architecture is the one provided by Amazon and its Web Services (AWS), through the creation of a prototypical application.The document is structured and developed following a top-down, breadth-first approach. This means that an argument may be talked about in all the chapters, according to the topic the chapter deals with, at an increasing level of specificity, up to the final implementation in the prototype, along with the considerations that need to be performed during all the phases of a software's realization.
