Low-code microservices orchestration with Syndesis

Low-code microservices orchestration with Syndesis

Recently I wrote about decoupling infrastructure code from microservices. I found that Apache Camel and Debezium provided the middleware I needed for that project, with minimal coding on my end. After my successful experiment, I wondered if it would be possible to orchestrate two or more similarly decoupled microservices into a new service–and could I do it without writing any code at all? I decided to find out.

This article is a quick dive into orchestrating microservices without writing any code. We will use Syndesis (an open source integration platform) as our orchestration platform. Note that the examples assume that you are familiar with Debezium and Kafka.

Decoupling microservices with Apache Camel and Debezium

The rise of microservices-oriented architecture brought us new development paradigms and mantras about independent development and decoupling. In such a scenario, we have to deal with a situation where we aim for independence, but we still need to react to state changes in different enterprise domains.

I’ll use a simple and typical example in order to show what we’re talking about. Imagine the development of two independent microservices: Order and User. We designed them to expose a REST interface and to each use a separate database, as shown in Figure 1:

Diagram 1 - Order and User microservices

Figure 1: Order and User microservices.
