I want to propose an architecture that consists of adopting a set of microservices using Activiti 8 Core to deploy processes and expose a REST API to execute these processes. I have a single constraint: these microservices do not contain the same process definitions, and they must be scalable.

I would like to know if the microservices can share the same database instance with the same Activiti schema. Is this scenario possible if we migrate to Activiti Cloud with multiple Runtime Bundles with different process definitions?
