Running Tableau Server on more than one machine is called a multi-node installation, or a cluster. Influences how often you will need to take backups of your system. Typically 2 vCPUs = 1 physical core for Tableau Server. In addition to the above considerations, you should evaluate the importance of disaster recovery in your organization and plan for a deployment that helps you meet your disaster recovery goals and objectives. Deploy a new Coordination Service ensemble. 2003-2022 Tableau Software, LLC, a Salesforce Company. Index and Search Server memory is added to all three nodes for redundancy and can be configured to improve performance by using the indexandsearchserver.vmopts TSM configuration option. Backgrounders run all types of jobs by default. All rights reserved, Minimum hardware requirements for installation, Virtual Machines and Public Cloud Deployments, Two Node Installation - Specialized for flow environments. In an extract-heavy environment, most data sources are extracts. The tolerance for downtime will vary for each organization and depends on the SLAs you have established in your organization. The development environment does not have to have identical hardware specs to the production and QA environments, unless the development environment is used for upgrade testing or participation in beta programmes. Regardless of your deployment size, Tableau Server provides you and your users with a consistent and reliable platform. vmware vplex Users and decision makers have come to depend on immediate access to data and self-service tools to answer their questions in real time and rely on these systems daily. Brad consults with Tableaus most performance-conscious clients to ensure their environments are running optimally. Tableau Prep Conductor is automatically configured one the node where you have backgrounder installed. An HA installation ofTableau Serverhas a minimum of three nodes and multiple redundant instances of key processes (the Repository, file store/Data Engine and coordination service) on different nodes. For more information, see Tableau Server external repository. All Rights Reserved.

For details on how to recover from a failure on the initial node, see Recover from an Initial Node Failure. One instance of Interactive Microservice Container is installed on a node that has Application Server enabled, and one instance of Non-Interactive Microservice Container is installed on a node that has Backgrounder enabled. Eric is also a contributing author to Tableau Your Data! With the right configuration, a distributed installation can also provide you with automatic repository failover.

His background is in networking, IT services development and virtualization/storage architecture. When deploying Tableau Server in the cloud, you can leverage all existing scaling abilities of the Tableau platform including hot topology. One instance of Interactive Microservice Container is installed on a node that has Application Server enabled, and one instance of Non-Interactive Microservice Container is installed on a node that has Backgrounder enabled. The relative workload of each licence type must be factored into hardware sizing. (This experiment was conducted in AWS, but the testing theory extends to any cloud provider.). Follow the pattern below to build your HA cluster: A 3-node Tableau Server HA deployment (note: Coordination Service and Client File Service are not explicitly shown). Thats why Tableau is designed to meet your most stringent SLAs. 2003-2022 Tableau Software, LLC, a Salesforce Company. You can decide how to install Tableau based on your organization's needs, and your resources, adding additional nodes and configuring Tableau for high availability. Single Server installations can also be expanded to multi-node installation as your workloads grow. Add Client File Service to every node that is running the Coordination Service. For more information see Disk Space Requirements. 2003-2022 Tableau Software LLC. Spreading the server processes out over multiple nodes can extend the reliability and efficiency of Tableau Server by providing redundancy and additional computing power. Active/Passive Repository across two nodes. Downtime is still possible in the event of an initial node failure, or when a node running Application Server (VizPortal) is recovering from a failure. The successful functioning of Tableau Server depends on a properly functioning Coordination Service. The goal is to minimize system downtime by eliminating single points of failure, and enabling detection of failures with failover where possible. Using node roles, you can configure where certain types of workloads are processed on your Tableau Server installation.

Today, more than ever, self-service analytics and data-driven decision-making are becoming the norm in organizations worldwide.

Highly available (HA) installationAn HA installation of Tableau Server is a special type of multi-node installation with a minimum of three nodes and multiple instances of key processes (the Repository, File Store/Data Engine (Hyper), Coordination Service, and Client File Service) on different computers. You cannot install a multi-node instance of Tableau Server on a combination of Linux and Windows nodes. This topic describes three baseline architectures that can be used as starting points for your Tableau Server installations. When a licensed process starts or restarts, the process checks with the Tableau Server License Manager service on the primary node to verify there is a valid license. For existing deployments, you will analyse Tableau Server data to evaluate workload and usage in addition to environment and sources of data. To support mission-critical use cases, you should deploy a high-availability (HA) cluster configuration with an external load balancer (Windows | Linux). For more information, see indexandsearchserver.vmopts. If you are adding Tableau Prep Conductor to your Tableau Server installation, we recommend you add a second node and dedicate this to running Tableau Server Prep Conductor. Adding additional instances of CFS to other nodes provides additional duplication of processes and so reduces the possibility of server downtime due to an issue with one of the CFS nodes. The table below illustrates how to plan for a range of RTO requirements: New hardware/VMs obtained in case of an outage, Dedicated hardware that is always running with identical configuration and topology to production, Backups are restored regularly to the DR environment, Restore latest backup to the cold standby environment, External load balancer/DNS routing that can be updated to point to the DR environment. When things go wrong, being able to quickly restore to the most recent backup is critical. For more information on licensing, see Licensing Overview. The diagram above shows the maximum for an 8 core node. You also need to make sure the computer you install Tableau Server on has adequate resources to handle the processes and the demands of users and data. Similarly, follow the best practices provided by your virtual infrastructure provider to make sure Tableau Server has access to the appropriate compute, memory, and data resources. For more information about initial node failure, see If an initial node fails below. Today, self-service analytics and data-driven decision-making are the norm in organizations worldwide. The most basic way to run Tableau Server is to install a single node. This is only a starting point and should not be considered a hard sizing rule beyond the initial deployment. There are various reasons why you might want to have a multi-node installation. Furthermore, deploying and integrating with diverse and heterogeneous enterprise IT platforms is becoming the only way to support the current and future analytical needs of the business. Note: All nodes in a multi-node cluster must have the same type of operating system. Taking a snapshot of a Tableau Server machine and restoring on a new machine is not supported. This is one of the primary reasons to move to a multi-node configuration. HA in Tableau Server is mainly achieved by: File redundancy with multiple File Store/Data Engine instances.

This is true even when an installation is configured for high availability. To calculate the minimum number of backgrounder processes to run on this node, divide the computers total number of physical cores by 4. The example configuration described above does not include Tableau Prep Conductor since it is a single node server. Influences how often you restore your backups to an alternative cluster and the amount of infrastructure investment. In an initial deployment of Tableau, you should estimate 600-800 Explorers per 8-core node, assuming 10% active users (interactive, concurrent requests made to Tableau Server, including consuming dashboards on a laptop or mobile device, web authoring, and connecting to and querying published data sources). His analytical style revolves around people and context, and in an industry consumed with defaults, he believes that data intelligence starts with giving people access to their information with collaboration in mind. For details, see Install and Configure Tableau Server. Having just a few, extremely large extracts could put your deployment in this category, as would having very many small extracts. Tableau Server can be installed on-premises with physical or virtual machines or in the cloud and supports Windows or Linux operating systems. Please note: This paper assumes you are running Tableau Server version 2018.2 or more recent, with Tableau Services Manager. If cost is a consideration, virtual hardware is also viable. By default Tableau Server installer configures the number of process instances based on the hardware on the machine. If this is the first time you are deploying Tableau Server, you should focus on your environment standards and sources of data. For more information on failover, see Repository Failover .

We use industry-standard security protocols and best practices, keep our users well informed, and quickly respond to security issues on the rare occasion that they arise. vmware vplex This reliance on data requires a high degree of availability and stability of the underlying systems. If there is a problem with the initial node and you have redundant processes on your other nodes, there is no guarantee that Tableau Server will continue to run. Mike is a 2015 Tableau Zen Master A 5-node Tableau Server HA deployment (note: Coordination Service and Client File Service are not explicitly shown). By integrating with AWS to configure an external repository for Tableau Server, you will be able to take advantage of these additional benefits of the cloud. Brad Fair and Eric Shiarla from InterWorks and Mike Roberts from Pluralsight bring a comprehensive understanding of the hardware, networking and integration requirements of enterprise customers, they provide a road map for Tableau Server planning and implementation. Tableau Server requires a minimum of a three-node configuration to provide redundancy and eliminate the single points of failure. The hardware recommendations for production Tableau Server installations below are based on the hardware that the Tableau team uses to test Tableau Server scalability. It is essential for enterprise architects and IT leaders to understand how Tableau Server scales with data, content, and users. Tableau is in compliance with Sarbanes-Oxley and has worked with a certified public accounting firm to perform an in-depth audit of the control objectives and activities for Tableau Cloud. High availability is achieved by eliminating single points of failure and detecting failures and setting up a reliable failover system.

To see when the last licensing check occurred, look at the log files in the ProgramData\Tableau\Tableau Server\data\tabsvc\logs\licenseservice folder. Based out of Chicago, he manages a team of consultants that are actively involved in some of the largest Tableau deployments in the world. Note: This configuration assumes that you do not have Tableau Prep Conductor enabled on your Tableau Server. Our licensing model supports redundant server components so youre only paying for production environments. High availability is about minimizing the system downtime. Step 1: Planning the Environment Starting in 2019.3, you can deploy Tableau Server Repository to Amazon Relational Database Service (RDS). Your production environment will support modern analytics using production and sandbox projects with content validation, promotion and certification processes all in one environment. To build in redundancy for HA related items such as repository, file redundancy, and failover, you need a minimum of three nodes. This node should have a minimum or 4 physical cores (8 vCPUs), and 16 GB of RAM. As Director of Data Analytics at Pluralsight, Mike Roberts has a wealth of experience and a varied background that encompasses databases, analytics, visualization and scripting. Below is the number of instances of the processes for an 8 core machine: Backgrounder: Minimum 2, maximum 4. Deployments where extracts are frequently refreshed, such as several times a day during business hours, should be isolated on specialized backgrounder nodes. This whitepaper outlines the high-availability and disaster-recovery features in Tableau Server 2018.2, after the release of the Tableau Services Manager (TSM). We suggest that you use these recommendations as starting points for your production deployments. Depending on how your installation was configured with CFS and Coordination Service, you may also need to take steps to redeploy these. Regardless of where you choose to deploy Tableau Server, properly-sized hardware is critical. For more information, see tsmconfiguration set Options. For Tableau Server the RPO cannot be shorter than the time it takes to complete a full backup of your server. The use of highly-redundant cloud infrastructure or on-premises VMs means that Tableau Server nodes can be quickly restored with minimal downtime. Dashboards and views may load more slowly than expected, and timeouts are possible, depending on how your system is configured and being used. - Fast and Easy Visual Analysis with Tableau Software. Backgrounder, Cache Server, and Data Server: Set to 2 instances. Step 5: Maintaining & Monitoring. With a simple restart of the server, you can also change the underlying machines supporting the platform as long as their public IP address does not change. Deployments where extracts are frequently refreshed (for example, several times a day during business hours) are often helped by more emphasis on the background process, which handles refresh tasks. This will allow administrators to test upgrades and participate in beta programmes in the test environment by restoring back production content. The second is detecting when there are failures and triggering reliable failover mechanisms as necessary. This reliance on data requires a high degree of availability to the underlying systems. When planning for disaster recovery (DR) in your Tableau environment, there are two main factors to consider: Recovery time objective (RTO) and recovery point objective (RPO). Your Tableau account team is available to assess your requirements and assist with sizing. Tableau Server is easy to install and configure yet has many features that can add complexity to deployments. When everyone in your company depends on data and analytics, you cant afford to let them down. This reliance on data requires a high degree of availability and stability of the underlying systems. The Tableau Server Repository is a PostgreSQL database that stores data about all user interactions, extract refreshes and more. This whitepaper outlines the high-availability and disaster-recovery features in Tableau Server 10. There are two common strategies for achieving HA. Using these workload coefficients, you can estimate the clusters capacity. The configuration of your Tableau Server can be different depending on your requirements and variables: For more information on Tableau Server scalability and the variables affecting scalability, see Tableau Server Scalability whitepaper. All other processes, only one instance of the process is installed, regardless of hardware. Scalability and performance are heavily dependent on external systems, such as sources of data, volume of data, network speeds, user workloads and workbook design, which can change rapidly as deployments progress. A number of processes are installed when you install Tableau Server. For more information, see Add a Load Balancer. Adding an external load balancer to make sure your installation is robust to Gateway failures and make sure that requests only get routed to functioning Gateway processes. A well-executed Tableau Server deployment consists of 5 essential steps: High availability is natively supported on server clusters with three or more nodes; each node contributes to the quorum, and the group helps verify each others health. For more information, see the Tableau Server high availability white paper. For example, for AWS installations, the 4 core minimum recommendation is equivalent of 8 AWS vCPUs. For example, for AWS installations, the 4 core minimum recommendation is equivalent of 8 AWS vCPUs. For more information, see tsm topology set-node-role. Recovery Point Objective (RPO), a measure of how much data loss your business can tolerate. In addition to your production environment, Tableau recommends one test environment for testing upgrades and server topology changes. This whitepaper outlines High Availability in Tableau Server 2018.2 with Tableau Services Manager. If you are installing Tableau Server in a virtual environment or a cloud-based deployment, see Virtual Machines and Public Cloud Deployments section later in this topic. It is achieved by eliminating single points of failure, and having a reliable failover mechanism. Index and Search Server: Index and Search Server memory can be configured to improve performance by using the indexandsearchserver.vmopts TSM configuration option. On one of the additional nodes, set the backgrounder to run only flows, and the other additional node to run all jobs except for flows. Use the tsm topology set-node-role tsm configuration to configure this setting.

If are using Tableau Prep Conductor to schedule and manage flows, and have an extract heavy environment, we recommend that you have at least 3 nodes and use the 3 node configuration described later in this topic. If not configured to use ATR, Tableau Server can continue to run for up to 72 hours after an initial node failure, before the lack of the licensing service impacts other processes. Important: Two-node configurations do not meet the minimum requirements for high availability. Note: Active users represent the interactive, concurrent requests made to Tableau Server, including consuming dashboards on a laptop or mobile device, web authoring, and connecting to and querying Published Data Sources. Review the corresponding link to the hardware platform that fits your enterprise standards: If you deploy Tableau Server in the cloud, using dedicated hardware and static allocation of RAM eliminates varied performance due to resource contention. There is less redundancy and fewer safeguards in the event of a problem with one of the server processes. Having a few extremely large extracts could put your deployment in this category, as would having many small extracts. Frequent extract refreshes: Refreshing an extract is a CPU-intensive task. 2003-2022 Tableau Software LLC. On the initial node, set the Backgrounder node role to run all job types including flows using the tsm topology set-node-role tsm configuration.
