Microservices With Spring Cloud Kubernetes

Spring Cloud and Kubernetes are the popular products applicable to various different use cases. However, when it comes to microservices architecture they are sometimes described as competitive solutions. They are both implementing popular patterns in microservices architecture like service discovery, distributed configuration, load balancing or circuit breaking. Of course, they are doing it differently. Continue reading “Microservices With Spring Cloud Kubernetes”

Circuit Breaking In Spring Cloud Gateway With Resilience4J

In the newest version of Spring Cloud Gateway (2.2.1) we may take an advantage of a new implementation of circuit breaker built on top of project Resilience4J (https://github.com/resilience4j/resilience4j). Resilience4J has been selected as a replacement for Netflix’s Hystrix, that had been moved to the maintenance mode. Of course, you can still use Hystrix as circuit breaker implementation, however it is deprecated and probably won’t be available in the future versions of Spring Cloud. A new implementation is called no different than just Spring Cloud Circuit Breaker. Continue reading “Circuit Breaking In Spring Cloud Gateway With Resilience4J”

Spring Boot Best Practices for Microservices

In this article I’m going to propose my list of “golden rules” for building Spring Boot applications, which are a part of microservices-based system. I’m basing on my experience in migrating monolithic SOAP applications running on JEE servers into REST-based small applications built on top of Spring Boot. This list of best practices assumes you are running many microservices on the production under a huge incoming traffic. Let’s begin. Continue reading “Spring Boot Best Practices for Microservices”

Secure Spring Cloud Config

If you are building microservices architecture on top of Spring Boot and Spring Cloud I’m almost sure that one of projects you are using is Spring Cloud Config. Spring Cloud Config is responsible for implementing one of the most popular microservices pattern called distributed configuration. It provides server-side (Spring Cloud Config Server) and client-side (Spring Cloud Config Server) support for externalized configuration in a distributed system. In this article I focus on security aspects related to that project. If you are interested in some basics please refer to my previous article about it Microservices Configuration With Spring Cloud Config. Continue reading “Secure Spring Cloud Config”
