  • How to Set up a Microservices Architecture in Ruby: A Step by Step Guide (Publication)
    https://www.toptal.com/ruby/how-to-set-up-a-microservices-architecture
    Microservices are one of the latest trends in software design. In a microservices architecture, the classic monolithic back-end is substituted by a suite of distributed services. This design allows better separation of responsibilities, easier maintenance, greater flexibility in the choice of technologies for each service, and easier scalability and fault tolerance. In this article, Toptal Freelance Software Engineer Francisco Temudo guides us in a step-by-step tutorial on how to build a microservices suite using Ruby.
