The Six Obstacles of Moving to Microservices

The talk Developers make mistakes. One of the most common mistakes is thinking that a new technical solution or paradigm will solve all the problems existing in a given Software Project. That won’t happen, but we’ll be tempted anyway to fall into this trap and embrace Microservices like if they are going to solve all our problems. In this talk, I wanted to share some real experience about the problems of moving to Microservices, and how we managed to overcome them with practical solutions. The talk was part of Codemotion Rome 2018. You can find the complete talk in the video below. If you’re interestedRead More →

E2E Tests with Cucumber

End-to-End Microservice Tests with Cucumber If you work with Microservices, you surely faced the situation in which some of your system processes only make sense after the information flows through several microservices. For instance, if you’re implementing an Event-Driven architecture, you certainly want to verify your Business Processes when events are propagated and other parts react to them. There are several frameworks you can use for that but, for its simplicity and perfect matching with Business requirements, Cucumber is a great option. Let’s get into the process of writing end-to-end scenarios using Cucumber. NOTE: this post doesn’t cover the use of Dependency Injection with CucumberRead More →

Mapping them into small teams in an organization also gives a lot of efficiency in development. However, going on the adventure of microservices knowing only the benefits is a wrong call: you need to know what you are facing and be prepared for that in advance. You can get a lot of knowledge from many books and articles on the Internet but, when you get hands-on-code, the story changes.Read More →

Introduction If you use Ribbon and Eureka in your Spring Boot application, you’ll notice that the default configuration is not optimal. Eureka takes a long time to figure out that a service went down unexpectedly and, in the meantime, your load balancer Ribbon will try to connect to the dead one. In other words, the eviction policy does not perform well by default. On the other hand, the official Eureka documentation discourages changing the leaseRenewalIntervalInSeconds parameter so, what can we do here? This post answers that question.Read More →
