Manual: Multi-node HA-ready production profile requirements and installation

This page walks you through the requirements and installation instructions for the multi-node HA-ready production profile.

Deployment profile overview


🚧

Important!

Linux and Kubernetes knowledge is required regardless of the deployment profile you choose. If you encounter issues installing and configuring Automation Suite, contact UiPath Professional Services.


Before choosing your deployment profile, see Supported use cases for single-node and multi-node installations.


The installation process generates self-signed certificates on your behalf. These certificates will expire in 90 days, and you must replace them with certificates signed by a trusted Certificate Authority (CA) as soon as installation completes. If you do not update the certificates, the installation will stop working after 90 days.
For instructions, see Managing certificates.


The multi-node HA-ready production profile is resilient to only one node failure. This means that you can lose only one server node. This restriction does not apply to agent nodes. You can lose as many agent nodes and still continue to use the cluster without downtime as long as enough overall cluster capacity is available.

Deployment profile Prerequisites Requirements Configuration Installation
Multi-node HA-ready production profile Minimum 3 Linux machines (RHEL 8.2, 8.3, 8.4, 8.5)
  • Additional Linux machine is required when using Task Mining
  • Additional Linux machine with GPU support is recommended when using Document Understanding
Multi-node HA-ready production machine requirements Configuring the machines
  • Microsoft SQL Server (2016, 2017, 2019 - Standard and Enterprise editions)
  • Additional Microsoft SQL platforms, such as Azure SQL Database or Azure SQL Managed Instance, as well as Amazon Relational Database Service are also supported as long as the Microsoft SQL Server database engine meets the requirements.
MS SQL Server requirements Configuring MS SQL Server
DNS N/A Configuring the DNS
TLS 1.2+ Updating the TLS protocol N/A
Trusted TLS, token-signing and SQL connection encryption certificates N/A Configuring the certificates
Load balancer N/A Configuring the load balancer
Proxy server
(optional)
N/A Configuring proxy on the machine

Configuring proxy during installation
Setting up Kerberos authentication
(optional)
N/A Setting up Kerberos authentication

🚧

Important!

You need root permission to install and deploy Automation Suite.
For more on the specific components that require root access, see Root privileges requirement.

Optimal node size

Larger node sizes are more efficient than smaller node sizes because of the fixed baseline resource overhead per node. For example, 3 x 32 cores nodes is more efficient than 6 x 16 cores nodes.

 

Microsoft SQL Server general requirements


The installation requires an external SQL server as a prerequisite.

📘

Note:

Make sure that the SQL server can be accessed from each cluster VM.

Microsoft SQL Server 2016, 2017, and 2019 Standard and Enterprise editions are supported.

The minimum hardware requirements for Microsoft SQL Server are:

  • 8 (v-)CPU
  • 32 GiB RAM
  • 256 GiB SSD
