Important: The Pega Customer Decision Hub application should be created on a different Pega environment with its own database and application servers separate from the ones used by Pega Customer Service and Pega Sales Automation applications. The Pega Customer Decision Hub application is a back-end analytical application with a typically smaller number of active users compared to the operational Pega Customer Service and Pega Sales Automation applications. Keeping the operational and analytical clusters separate helps ensure easier maintenance and decreases upgrade complexity.
