Tableau Architecture & Server Components
Tableau Server is structured in a manner to interface numerous data levels. It can associate customers from work area, portable, and web. Tableau Desktop is a hearty data visualization tool. It is profoundly accessible and secure.
It can run on both virtual and physical machines. It is a multi-client, multi-process and multi-strung framework.
Giving such powerful highlights requires a hearty design. How about we study the Tableau Server Architecture in this instructional exercise.
Tableau Server Architecture
The various layers used in the Tableau server are given in the following architecture diagram

Let’s study the different components of Tableau Architecture
The essential part of Tableau Architecture is the Data sources it can associate with it.
Tableau can interface with numerous data sources. These data sources can be on-premise or distantly found. It can associate with a database, exceed expectations document, and a web application all simultaneously. Tableau can interface data from heterogeneous conditions. It can mix the data from different data sources. It can likewise make the connection between different kinds of data sources.
The Data Connectors give an interface to associate outer data sources to Tableau Data Server.
Tableau has in-assembled ODBC/SQL connector. This ODBC Connector can associate with any databases without utilizing their local connector. Tableau has an alternative to choose both live and concentrate data. In view of the use, one can be effectively exchanged among extricated and live data.
Live Connection or Real time data: Tableau can associate with constant data by connecting to the outer database legitimately. It utilizes the framework of existing database framework by sending dynamic MDX (Multidimensional Expressions) and SQL proclamations. This component can connection to the live data with Tableau as opposed to bringing in the data. It makes great the venture done by an association on a quick and streamlined database framework. In numerous endeavors, the size of the database is enormous and is refreshed intermittently. In those cases, Tableau fills in as a front-end visualization tool by associating with the live data.
Extricated or In-memory data: Tableau has an alternative to separate the data from outer data sources. We can make a nearby duplicate as tableau remove record. It can separate a huge number of records in Tableau data motor with a solitary snap. Tableau’s data motor uses stockpiling, for example, RAM, ROM and reserve memory to store and procedure data. Utilizing channels, Tableau can extricate hardly any records from a gigantic dataset. This improves the exhibition, particularly while chipping away at enormous datasets. Extricated or in-memory data permits the clients to visualize the data disconnected, without associating with the data source.
Components of Tableau Server
The different components present in a Tableau server are:
- Application Server
- VizQL Server
- Data Server
A) Application Server:
The application worker is utilized to give the validations and approvals. It handles the organization and authorization for web and portable interfaces. It guarantees security by recording every meeting id on Tableau Server. The director can design the default break of the meeting in the worker.
B) VizQL Server:
VizQL worker is utilized to change over the inquiries from the data source into visualizations. When the customer demand is sent to VizQL process, it sends the question legitimately to data source and recovers information as pictures. This picture or visualization is introduced to the client. Tableau worker makes a store of visualization to lessen the heap time. The reserve can be shared across numerous clients who have the authorization to see the visualization.
C) Data Server:
Data worker is utilized to manage and store the data from outer data sources. It is a focal data management framework. It gives metadata management, data security, data stockpiling, data association and driver necessities. It stores the pertinent subtleties of data set, for example, metadata, determined fields, sets, gatherings, and boundaries. The data source could remove data also make live associations with outer data sources.
The entryway channelizes the solicitations from clients to Tableau segments. At the point when the customer makes a solicitation, it is sent to outside burden balancer for handling. The passage fills in as a wholesaler of procedures to different segments. If there should arise an occurrence of nonappearance of outside burden balancer, entryway additionally fills in as a heap balancer. For single worker design, one essential worker or entryway manages all the procedures. For different worker arrangements, one physical framework functions as essential worker while others are utilized as laborer workers. Just one machine can be utilized as an essential worker in Tableau Server condition.
The dashboards and visualizations in Tableau server can be viewed and edited using different clients. The Clients are Tableau Desktop, web browser and mobile applications.
|Tableau Desktop||Tableau Desktop is a business analytics tool. It helps to create, view and publish dashboards in Tableau Server. Users can access various data sources and build visualizations in Tableau Desktop.|
|Mobile||The dashboards from the server can be interactively visualized using mobile browsers and applications. The browser and application can be used to view and edit the contents in the workbook.|
|Web||Web browsers such as Google Chrome, Safari, Firefox and internet explorer support the Tableau server. The contents and visualizations in the dashboard can be edited through these web browsers.|
- The architecture of Tableau Server is designed to connect different data sources securely.
- Data Server is the first layer in the architecture. It helps Tableau to connect data in various heterogeneous environments.
- Data connector is the second layer. It helps to connect to various databases using its ODBC connector.
- Tableau can connect the real time live data by connecting the database directly. It can also extract a local copy of data through its in-memory data store for faster processing.
- The components such as Application Server, VizQL Server, and data server act as the third layer.
- The application server is used for authentications and authorizations.
- VizQL is used to convert the SQL query into visualizations.
- Data Server is a centralized data management system used in the architecture.
- A gateway is used to distribute the processes into different components.
- The fourth layer of the architecture are the clients such as Tableau Desktop, web and Mobile.
