Modeler Services Professional and Workgroup run on the public cloud available in three different regions, America, Europe and Asia. When the service is first set up Modeler determines the appropriate region to run from based on the requestors location. The models, and any associated documentation and data, will stay within that region for the duration of the subscription. With Workgroup, the region is determined by the location of each member of the subscription, ensuring each individual’s models and data stay within their region for the duration of the subscription. For Enterprise the service is only available as a single-tenant environment, stored in a location of the customer’s choice, and where models and data are isolated from other organisations subscriptions. Modeler Services is a Software as a Service (SaaS) environment backed by Microsoft Azure.
