The execution servers allow you to execute the Jobs (processes) developed with Talend Studio from the Talend Administration Center web application.
When working with Talend Studio local projects, you can enable the authentication on Talend JobServer based on the users.csv file. For more information, see Enable user authentication for Talend Studio local projects.
When working with Talend Studio remote projects, the authentication on Talend JobServer is based on Talend Administration Center. For more information, see Configure user authentication for Talend Studio remote projects and Job Conductor using Talend Administration Center.
Note that you can also use Talend Runtime servers to deploy and execute Jobs tasks if these Jobs are linked with Services or Routes, but these servers are especially used to deploy and execute Services, Routes, or even generic OSGi features. For more information about the installation of Talend Runtime, see Installing Talend Runtime.
