What is installed along with the first instance of Application Server on a node?

The Interactive Container Service is installed alongside the first instance of the Application Server on a node. This service is essential for managing user interactions within Tableau Server. It enables the web-based interface for users to access dashboards and reports, facilitating real-time data interaction. When the Application Server is initiated for the first time, it sets up the environment necessary for managing requests and delivering content, which includes the Interactive Container Service to handle user sessions and provide dynamic data visualizations.

This installation is crucial because the Application Server handles tasks such as processing requests from clients, managing the content published to Tableau Server, and ensuring that users receive updates when they interact with data. In contrast, services like the License Manager are concerned with managing licensing-related tasks, and the Non-Interactive Container Service deals with background tasks that do not require user interactions. These components serve different purposes and are not critical to the initial setup of the Application Server, making the Interactive Container Service the appropriate choice when this server is first installed on a node.
