When you preview or run mappings, profiles, SQL data services, and web services in the Analyst tool or the Developer tool, the application client sends requests to the Data Integration Service to perform the data integration tasks. When you start a command from the command line or an external client to run mappings, SQL data services, web services, and workflows in an application, the command sends the request to the Data Integration Service.
Create and configure a Data Integration Service in the Administrator tool. You can create one or more Data Integration Services on a node. Based on your license, the Data Integration Service can be highly available.
