We define a method to automatically synthesize efficient distributed implementations from high-level global choreographies. A global choreography describes the execution and communication logic between a set of provided processes which are described by their interfaces. At the choreography level, the operations include multiparty communications, choice, loop, and branching. A choreography is master triggered: it has one master to trigger its execution. This allows us to automatically generate conflict-free distributed implementations without controllers. The behavior of the synthesized implementations follows the behavior of choreographies. In addition, the absence of controllers ensures the efficiency of the implementation and reduces the communication needed at runtime. Moreover, we define a translation of the distributed implementations to equivalent Promela versions. The translation allows verifying the distributed system against behavioral properties. We implemented a Java prototype to validate the approach and applied it to automatically synthesize micro-service architectures. We also illustrate our method on the automatic synthesis of a verified distributed buying system. 1. Introduction Developing correct distributed software is notoriously difficult. This is mainly due to their complex structure that consists of interactions between distributed processes. We mainly distinguish two possible directions to cope with the complexity of the interaction model: (1) high-level modeling frameworks [7]; and (2) session types [6, 22, 8, 37, 18, 11]. The former facilitates expressing the communication models but makes efficient code generation difficult. High-level
