Tableau
Tableau Server is a business intelligence application that allows its users to organize, edit, share and collaborate on the Tableau Dashboard. While Tableau Online is a paid plugin that fully hosts your data in Tableau.
Tableau Server allows you to store data in your selected cloud like Tableau Cloud storage or internal server. So data management is easy with Tableau Server. While Tableau Desktop is designed for you to create a dashboard, the Tableau server is built to organize and share those dashboards for you and your organization. Tableau Server allows you to edit your dashboards, while choosing who and how much they have access to them.
Term licensing arrangements.
The metric that allows use of Tableau Server determines the term license model for Tableau. Subscription licenses are another name for term licenses. Right now, Tableau offers subscription licenses for use of Tableau Server. Customers who use the subscription license model must pay an annual subscription fee. The software will stop functioning if the subscription runs out.
Role-based subscriptions or core-based subscriptions are the two types of subscription licenses. An Updatable Subscription License (USL) is a license that can be purchased that includes a single license key for all roles and features. To represent the entire purchase on Tableau Server, only one key needs to be activated.
One role type per key was included in earlier subscription licenses (non-USL), and the licenses had to be “stacked” and activated simultaneously to get Tableau Server to work with the purchased configuration.
You can set up Tableau Server on a single computer or a cluster of computers with a role-based license. Each person who uses Tableau Server needs to have a license and be given a role. Admins can add users based on the types of licenses that are still available.
The quantity of user accounts in Tableau Server is not limited by a core-based license. The maximum number of computer cores that you can use to run Tableau Server is instead specified by the license. As long as the combined number of cores across all computers does not go beyond what the license allows, you can install Tableau Server on either a single computer or a multi-node cluster of computers.
Not all applications installed with Tableau Server have an effect on how many cores are used in total. “Licensed processes” are a subset of processes. “Only computers running licensed processes are used to calculate core licensing. The cores on a computer that has one or more licensed processes installed on it count toward the total number of cores used.
License model with roles.
Role-based term licenses are a feature-rich offering from Tableau that come in a range of prices. Display, Viewer, Explorer, and Creator are the available four categories of role-based term licenses.
Display licenses enable users to share and present Tableau content to a large internal audience of users who merely view dashboards on shared displays without engaging with them. The maximum site role of Viewer is assigned by administrators when using a Display license; there is no separate site role for Display licenses. Instead, administrators create a dedicated login account that is not the same as a user’s login account for each licensed Display location.
User interaction with workbooks in Tableau Server is permitted by viewer licenses. Users with viewer licenses can also access Tableau Mobile, annotate workbooks, export visuals in different formats, download workbook summary data, make their own subscriptions, and sign up for data-driven alerts.
The capabilities offered by Viewer licenses are also included with Explorer licenses, which are similar to the user-based licenses available in earlier Tableau Server releases. Using a web browser to create workbooks and access the full range of collaboration tools are both made possible by an Explorer license.
Creator licenses give access to Tableau Desktop, Tableau Prep Builder, and a variety of other features when using Tableau Server. All of the capabilities offered by the Explorer license as well as the following ones when using Tableau Server are permitted by a Creator license.
- Create and publish fresh workbooks using a new data source.
- In the Data pane, edit embedded data sources.
- New data connections, then publish them.
- Use Tableau Desktop and Tableau Prep Builder’s login-based license management activation.
Core licensing model
In a core Tableau licensing model, as opposed to how many additional users can be added, the license specifies the total number of computer cores the server can use. This indicates that the server can accommodate practically an infinite number of users (as Explorers or Viewers; the previous term for these kinds of roles was “interactors”). Role-based licensing does not support Guest User accounts, but core-based licensing does.
Those site roles will be hidden when adding users because they are not included in the core licensing for the server’s Creator seats. New content must be created and published to Tableau Server using a separate license. One of the following needs to be purchased for content publishing in a core-based organization:
- Either one or more users with a role-based Creator license, which covers Tableau Desktop and Tableau Prep Builder.
- Using an Explorer (can publish) site role and at least one licensed Tableau Desktop with a legacy Tableau Desktop product key. This makes it possible for the user who owns a license for Tableau Desktop to publish to Tableau Server.
Data management with Tableau
The Tableau Prep Conductor and Tableau Catalog are included in the Data Management license for a single deployment of Tableau Server, which may be core-based or role-based.
In order to run flows for Prep Conductor, Data Management may need resource cores, which refers to the amount of processing power. Resource Core purchases for servers with core-based licensing must include a minimum of four.
