SPSS Modeler 18.1 Lightweight License: Can it be Shared Across VMs?

Goal: Reduce Licensing Costs for Low‑Traffic Workloads
SPSS Modeler 18.1 introduced a lightweight license that allows per‑instance activation, eliminating the need for full enterprise licenses. This feature is attractive for environments that run only a few jobs each month.
Current Constraints
The lightweight license permits 30 days of continuous use before reactivation, but it explicitly does not support multi‑user concurrent sessions within a single instance. Moreover, the license server automatically deactivates a license if the application remains idle for 90 days, which can disrupt intermittent workloads.
Unresolved Decision Point
When deploying SPSS Modeler in a containerized environment, it is unclear whether the lightweight license can be shared across multiple virtual machines without triggering license violations or unintended deactivation.
Specific Questions
- Is the lightweight license intended to be used concurrently on separate VMs within the same container cluster?
- Will the license server detect overlapping activations and automatically deactivate one or more instances?
- What configuration changes, if any, are required in the license.config file to maintain a single active license across multiple VMs?
