Scaling Nodes

Applies to: Kyvos Enterprise Kyvos Cloud (SaaS on AWS) Kyvos AWS Marketplace

Kyvos Azure Marketplace Kyvos GCP Marketplace Kyvos Single Node Installation (Kyvos SNI)

Important

To scale BI Server and Web Portal nodes in Azure Marketplace, the network interface attached to the existing BI Server and Web Portal nodes must be in the same resource group as the BI Server, Web Portal and other resources. If the network interface attached to the BI Server and Web Portal machines exist in a resource group other than the BI Server and Web Portal machine's resource group, assign the Microsoft.Network/virtualNetworks/subnets/join/action permission to MI (Managed Identity) over VN (Virtual Network) by creating a custom role.
For Azure Enterprise, create a custom role with the required permissions. While creating a custom role, add the Resource IDs for the following services in the assignable scope:
- Application Gateway
- Virtual Network
- Network Security Group
Once the custom role is created, it must be assigned to each of the above listed services.

Increasing Nodes

Note

Increased nodes that handle the creation and addition of nodes. An additional field for the zone will be displayed in the environment that supports the zone scaling.
The steps for increasing a node for Query Engine, BI Server, and Web Portal are the same. An additional input for Load Balancer will be displayed for Web Portal scaling.
Currently, the Marketplace and Kyvos Enterprise do not support zones. The zone list is displayed in the Managed Service as it supports zones.
Adding Kyvos Reporting Service node is supported in Managed Service and Marketplace.

To increase a Kyvos Core Service node, perform the following steps.

On the navigation pane, click Kyvos and Ecosystem> Nodes and Services > Overview.
On the Overview page, you will see the number of nodes for Kyvos Core Services and the number of service instances (BI Server, Query Engine, and Web Portal) configured for the Kyvos cluster.
Click Create > Kyvos Core Service Node. The Create Kyvos Core Service Nodes (Azure Marketplace) dialog box is displayed.

Note

Ensure that the dialog box to create Kyvos Core Services for Managed Service deployment may vary.

This will validate the instance group. If it is validated, the Validated Successfully message is displayed. In case of any error, you need to provide a valid instance group name.

Enter your Kyvos Manager password to create the node and click Create. The Nodes will be created, and you will be redirected to the Operations page where you can view the status.
