Distributed Service Task execution

[tsvetval]

Hello,
We have such a situation:
Our system consist of several microservices (based on Spring) and each service can do some work (i.e process some Service Task). We have a definition for the process that contains several Service Tasks and this Service Task can be executed only by appropriate Microservices.

for example:

Service A can process only ServiceTask 1
Service B can process only ServiceTask 2
etc.

Is it possible to setup Camunda in such a way?

Hi @tsvetval,

Welcome to the Camunda forum

Of course, yes. You can have centralized workflow engine which serves multiple microservices orchestration. Microservices can connect to in order to deploy and execute workflows, technically that might be via REST (Camunda BPM) or gRPC (Zeebe).

Orchestration process microservices

Hi Ruslan. There is no general answer to that. It really depends how you design the boundaries of your systems. So yes, it could be that you have an own microservice, that handles the policy application and owns a workflow that probably orchestrate the other services. It could also be that the quote microservice owns that workflow as you decide it is responsible for the quoting until the quite is really checked out. The relationship of the BPMN and microservices is a “simple” service invocatio…
