I will be in the National School of Computing Sciences of Tunisia (ENSI Tunisia), from the 2nd to 4th January 2020, to animate a 20 Hours workshop, about Microservices in Java and how to deploy them as Docker Containers to Kubernetes. The event is organized by Mrs Rim Drira.
The Microservices Architecture World, we can meet many concepts and patterns, like the Centralized Configuration, Circuit Breaker, Service Registry and Discovery, etc..
