The Six Obstacles of Moving to Microservices

Microservices are not always the solution We, as developers, make mistakes. For example, one of the most common ones 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. Microservices Architecture is one of the most popular traps. When we read about the benefits of Microservices, we may believe that, just by splitting our huge project into smaller pieces and applying some theoretical advice, our ways of working will improve drastically. However, that’s not normally the case: Microservices come with many disadvantages.Read 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 should verify your Business Processes end-to-end, including the complete event chain that spans across services. 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 Cucumber in SpringRead More →

Learn Microservices with Spring Boot

A practical book about Microservices Microservices are getting very popular these days. This type of software architecture has a lot of advantages like flexibility and ease at scale. 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 are the new paradigms and changes that you will face and prepare for that in advance. Books and articles can provide you with some knowledge 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 →
