What is hybrid for Talend Cloud

Talend Cloud lets you install and host on-premises versions of your Talend Data Stewardship and Talend Data Preparation applications. This setup allows you to store sensitive data behind your firewall, while still managing your users and the rest of your platform from Talend Cloud.

You can enable hybrid individually for each of these applications. While installed on premises, they are still bound to your Talend Cloud license. Platform administration, such as user and account management, remains in Talend Cloud for all applications.
All communication between hybrid Talend Data Stewardship or Talend Data Preparation and Talend Cloud is initiated from the hybrid applications, and never from Talend Cloud to the hybrid applications. Consequently, you do not need to allow inbound communication from the Internet to your hybrid applications.
Information noteImportant: Your data is stored locally and never shared with Talend Cloud. The definition of the semantic types and the data quality rules are stored in Talend Cloud but not the data to which they apply.

Even with applications located on different domains, logging in to Talend Cloud and switching between the applications works seamlessly.

Applications that are available for hybrid setup are:

  • Architecture diagram of Talend Data Stewardship prior to version 8.0 R2022-07 in hybrid mode
    The diagram has two sections: on premises and Talend Cloud. In the on premises section, Talend Remote Engine receives Job run scheduling instructions from Talend Management Console, and reads and writes tasks to Talend Data Stewardship. Talend Data Stewardship communicates with Talend Dictionary Service using Kafka. In the Talend Cloud section, Talend Data Stewardship users, roles, and license are managed from Talend Management Console.
  • Architecture diagram of Talend Data Stewardship version 8.0 R2022-07 and later in hybrid mode
    The diagram has two sections: on premises and Talend Cloud. In the on premises section, Talend Remote Engine receives Job run scheduling instructions from Talend Management Console, and reads and writes tasks to Talend Data Stewardship. Talend Data Stewardship communicates with Talend Dictionary Service through the Hybrid Link Service and Kafka. Talend Dictionary Service synchronizes semantic types and data quality rules through the Hybrid Link Service. In the Talend Cloud section, Talend Data Stewardship users, roles, and license are managed from Talend Management Console.
    The Hybrid Link Service enables the synchronization of semantic types and data quality rules stored on the cloud with on-premises instances.
