Scaling nodes and services

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

For Kyvos Free deployment in Azure and AWS Marketplace, the 'Nodes and Services' page will not be available.
For AWS Managed Services, If you have a cluster deployed with releases earlier than 2023.5, ensure that the IAM policy is updated before using this feature.

You can now manage Query Engines, BI Server nodes, and Query Engine disks that must be attached to the Query Engine node directly from the Nodes and Services > Overview page. This page displays the number of nodes and disk details added to each Query Engine node and the number of configured services such as BI Server, Web Portal, and Query Engines on the cluster nodes. You can also view the specific details of these services. This will take you to the Node and Service Mapping page.

This allows for efficient modification of the Query Engine node count and disk allocation for cloud deployments.

Creating and add node for Marketplace

Important

To increase or decrease BI Server nodes via scaling in Azure Marketplace, the network interface attached to the existing BI node must be in the same resource group as the BI Server and other resources. In cases where the network interface attached to the BI machine exists in a resource group other than the BI 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.

Steps for creating a node for Query Engine and BI Server are the same for both Azure and AWS Marketplace.

To create and add a required 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, BI Server Storage (in GB), the size of the disk attached to each Query Engine node, and the number of service instances configured for the Kyvos cluster.
Click Create. The Create Node dialog box is displayed.

Enter the number of nodes for Query Engines and BI Server that you want to create, and then enter your Kyvos Manager password to create the node. The Nodes will be created and you will be redirected to the Operations page where you can view the status.

Terminating a node for Marketplace

Similarly, you can delete a node for Query Engine and BI Server by clicking the three dots, and then click Terminate Nodes.

The Terminate Nodes dialog is displayed. Enter the number of nodes you want to terminate, and then enter your Kyvos Manager password to delete the node.

Note

The BI Server node count input is displayed for Azure and AWS Marketplace.

Click Terminate. The node will be deleted.

Adding a disk for Marketplace

Steps for adding a disk for Query Engine node is the same for both Azure and AWS Marketplace.

To add a disk for Query Engine Storage, perform the following steps.

On the navigation pane, click Kyvos and Ecosystem > Overview.
On the Overview page, you will see the number of nodes, BI Server Storage (in GB), the size of the disk attached to each Query Engine node, and the number of service instances configured for the Kyvos cluster.
Click Add Disk.
The Add Disk dialog box is displayed.
Enter the number of disk you want to add to the Query Engine node, and then enter your Kyvos Manager password. The disk is added to the Query Engine node and you will be redirected to the Operations page where you can view the status.

Deleting a disk from Marketplace

To remove the disk from the Query Engine node, click the three dots and then click Delete Disk.
The Delete Disk dialog is displayed.
Enter the number of disk you want to remove, and then enter your Kyvos Manager password.
Click Delete. The disk will be deleted.

Creating a node for AWS Managed Services

To create a 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 and the number of service instances configured for the Kyvos cluster.
Click Create. The Create Node dialog box is displayed.
Enter the number of nodes for Query Engines and BI Server that you want to create for the required zone, and then enter your Kyvos Manager password to create the node. The Nodes will be created in that zone and you will be redirected to the Operations page where you can view the status.

Terminating node for AWS Managed Services

To terminate node from AWS Managed Services, perform the following steps.

Delete a node for Query Engine and BI Server by clicking the three dots, and then click Terminate Node.
The Terminate Node dialog is displayed. Enter the number of nodes for Query Engine and BI Server you want to terminate, and then enter your Kyvos Manager password to delete the node. The node will be deleted.
Click Terminate. The Nodes will be deleted and you will be redirected to the Operations page where you can view the status.

For other deployments

Similarly, for cloud deployments (Azure, AWS, GCP), and on-premises, you can add or delete a node.
