A common concern related to cloud based services is the prevention of commingling of data that belongs to different customers. On Demand Migration has architected its solution to specifically prevent such data commingling by logically separating customer data stores.
Customer data are differentiated using a Customer Organization Identifier. The Customer Organization Identifier is a unique identifier obtained from the Quest On Demand Core that is created when the customer signs up with the application.
This identifier used throughout the solution to ensure strict data separation of customers' data in Elasticsearch storage and during processing.
A separate Elasticsearch server instance is used for each customer.

The process of registering
On Demand Migration does provide the common authentication via Quest Identity Broker. Quest On Demand is configured with default roles that cannot be edited or deleted, and also allows you to add custom roles to make permissions more granular. Each access control role has a specific set of permissions that determines what tasks a user assigned to the role can perform. For more information on role-based access control, please refer the Quest On Demand product documentation.
