The Talend Data Services Platform functional architecture is an architectural model that identifies Talend Data Services Platform functions, interactions and corresponding IT needs. The overall architecture has been described by isolating specific functionalities in functional blocks.

The following chart illustrates the main architectural functional blocks.

Several functional blocks are defined:

  • The Clients block includes one or more Talend Studio(s) and Web browsers that could be on the same or on different machines.

    • From the Studio, you can carry out data integration or data service processes, mediation routes and services, and publish them on the Artifact Repository.

    • From the Web browser, you can connect to the remotely based Administration Center through a secured HTTP protocol.

  • The Server block includes a web-based Administration Center (application server). The Administration Center enables you to set up the execution of the tasks that handle Routes or Services execution into the Talend Runtime.

  • The Repositories block represents the SVN or Git server and the Nexus Artifact Repository.

    • The SVN or Git server is used to centralize all project metadata like Jobs, Business Models, Routines, Routes, Services, shared between the different end-users, and accessible from the Talend Studio to develop them and from the Talend Administration Center to publish, deploy and monitor them.

    • The Nexus Artifact Repository is used to store all the Routes and Services that are published from the Studio and are ready to be deployed in Talend Runtime.

  • The Talend Execution Servers block represents one or more Talend Runtimes (execution container) deployed inside your information system. The Talend Runtime deploys and executes the routes and services retrieved from the Nexus Artifact Repository according to the set up defined in the Administration Center via the web application.

  • The Databases block represents the Administration, the Audit and the Monitoring databases.

    • The Administration database is used to manage user accounts, access rights and project authorization, and so on.

    • The Audit database is used to evaluate different aspects of the Jobs implemented in projects realized in Talend Studio with the aim of providing solid quantitative and qualitative factors for process-oriented decision support.

    • The Monitoring database is used to monitor service calls.
