Hi, I work in a performance team, and sometimes I have to size projects that use Kubernetes with Spring Boot and Openjdk11, in a Kubernetes environment. More precisely on Openshift. It’s possible, this can work, but not out of the box. It’s not a good choice for a low consumption microservice architecture and hard to customize in Kubernetes. Spring Boot is an amazing framework for Java or Kotlin developments. It permit to make quick and secure deliveries on your projects, and a lot of developers know and use it. However Spring and OpenJDK have delivered their first release over 10 years ago, when systems resources were grown up years over years. Today we have the opposite phenomenon. We try to downsize ours apps to have microservices using less consumption on shared infrastructures. And we gonna see that those Java stuff aren’t good at this game.
