Reference Architecture for Flowable

Hi is there a reference architecture for Flowable showing the following:

  1. High Availability Setup
  2. Disaster Recovery Setup
  3. What All services are run and on which server.
  4. What all Hardware/Software are needed to run Flowable?
  5. Is there a Flowables Microservices Reference Architecture?
  6. What is the max load that Flowable has been tested with in terms of concurrent users/sessions.
