an i control processes like(change business rules -roles ) in real-time
> I would like to say Yes, this is the core functionality of Bonita ! You can access all these information, and change them directly (upload a new process, change users, roles....)
how many users can be included in developed system??can i use cloud-support free if there is necessary
> Bonita does not have any limitation on the number of users. For the usage, no limitation. For development, when you use the Community Studio, no limitation. When you use the subscription Studio, you must have one license per Studio, contact the sale department, honestly, this is not expensive.
For the Cloud Support Free, you can deploy the solution where you want, on-premise, on a cloud. Bonita has a Cloud offering, which takes care of all the logistics (no server deployment then, no migration), you are free to choose the best solution you want!
But please contact the Bonitasoft company to get detailed information.
