The following diagram illustrates the architecture behind Talend Data Stewardship and Talend Dictionary Service when set up 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 server(s).
- 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.
