Boundaries of Microservices: How to Build Them and How to Cross Them

Workshop




This two-part Java based workshop explores practices for defining the right boundaries between microservices, followed by ways to exchange data across these boundaries.

Defining Service Boundaries With DDD

The first part of the workshop focuses on defining the borders between microservices. How to split up your big problem into clearly defined microservices. In real life everything is related, and seeing the individual trees in the big picture of the sprawling forest is challenging. This is where Domain Driven Design (DDD) comes to the rescue. After a short presentation about DDD, we’ll get hands-on with an actual problem to end up with a working program.

Data Streams to Cross Boundaries

In the second part we’ll discuss why microservices must avoid tight coupling and how they still can share data. Based on Kafka, Debezium and Kubernetes, our microservices will produce and consume data streams. We’ll also use change data capture to stream data changes directly out of a database, without any application changes needed. We’ll touch on how to set up Kafka clusters on OpenShift via the Strimzi project and how to monitor and tune them for performance and resilience.
