I have a use case where multiple users need to run multiple simultaneous solvers.

Is there a best practice in scaling out Optaplanner for multitenancy?

Just to be clear I'm not interested in scaling out a single optimization run but instead multiple solvers.

So I'm looking for pros and cons for:

- multiple solvers in the same JVM

- multiple JVM:s on a single machine (with multiple solvers)

- multiple machine setup

- virtual machine vs lxc (Docker) vs bare metal

I'm also interested in provisioning of rules etc 

Regards,

Mats
