Asynchronous Queue Based Approach for Building Reactive Microservices

To achieve scalability and flexibility in larger applications a new approach arises, named by Microservices (MS). However MS architectures are at their inception and are even more a concept than a fully mature design pattern. One of the hardest topics in this approach is how to properly migrate or develop a single microservice, in terms of scope, efficiency and dependability. In this sense, this work proposes a new architectural model based on high-level architecture pattern of reactive programming to the internal structure of a new microservice. The new model of microservices are internally coordinated by asynchronous queues, which allowed to preserve compatibility with most monolithic components and provide an encapsulation process to enable its continuity. A comparative study between the standard approach and the proposed architecture was carried out to measure the eventual performance improvement of the new strategy.
