Camunda and Microservices Architecture

[asanchez]

Apologies for my broad question.

Could anyone explain what’s the best way to utilize Camunda in a MIcroservices Architecture?

We’re currenly using the all-in-one camunda-bpm-tomcat-7.6 distribution, but it does not seem the way to go as we end up having to deploy some of our components in Tomcat lib directory.

Hi @asanchez,

It is possible to operate Camunda in a Microservices Architecture where the services are only loosely coupled to the processes that orchestrate them (and therefore Camunda). The Camunda feature that can be used for these cases is called external tasks, see https://docs.camunda.org/manual/7.8/user-guide/process-engine/external-tasks/.

Some links for further reading:

• The right way to implement camunda workflows with micro services (c#)

Cheers,
Thorben
