Architecture of Talend Data Stewardship in cluster mode

This architecture is composed of several functional blocks:

• A Load Balancer, that distributes the workload from the different users accessing the Talend Data Stewardship instances at the same time as well as the Talend Dictionary Service servers.
  Information noteTip: The same Load Balancer can be used for Talend Data Preparation, Talend Data Stewardship and Talend Dictionary Service. In addition, the Load Balancer can be either physical or logical.
• The Talend Data Stewardship instances.
• The Talend Dictionary Service instances that you can optionally install if you want to add, remove, or edit the semantic types used on data in Talend Data Stewardship.
• A block containing the various components necessary for Talend Data Stewardship and Talend Dictionary Service to work, namely several instances of MongoDB for storage, Kafka and ZooKeeper for messaging, and an instance of Talend Administration Center to manage authorizations.
