Important

  • For GCP,

    • If using shared VPC, the post-upgrade permission (compute.subnetworks.use) is required to scale Kyvos nodes for the GCP Marketplace.

  • The post-deployment steps are required if you use an existing Virtual Network while deployment and required to scale the Kyvos Web Portal and BI Server nodes.

  • To scale Web Portal nodes on GCP, the deployment script currently does not support creating a load balancer. Therefore, you will need to manually create an external Load Balancer. For further details, see the Configuring External Load Balancer for GCP section.

  • For Kyvos Free deployment in AWS, Azure, and GCP Marketplace, the scaling nodes are not supported.

  • All the cluster nodes must be up for creating BI Server, Query Engine, and Web Portal nodes in AZURE and GCP cloud. 

  • In the AWS Managed Service, you can specify the availability zone while creating and terminating a node.

From the Nodes and Services > Overview page, you can manage scaling for the following:

  • Nodes for supported Kyvos core services (Query Engine, BI Server, and Web Portal)

  • Disk for Query Engine node

On the Overview page, you can view the number of nodes for each supported Kyvos services and disk details added to each Query Engine node and BI Server nodes.

This allows for efficient modification of the Query Engine, BI Server, and Web Portal node count and disk allocation for cloud deployments.

To scale nodes and services, do the following:

Creating and add Kyvos Core Service Node for Marketplace 

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.

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

To create and add a Kyvos Core Service node, perform the following steps. 

  1. On the navigation pane, click  Kyvos and Ecosystem> Nodes and Services > Overview.  

  2. On the Overview page, you will see the number of nodes for Kyvos Core Services; BI Server Storage and Query Engine Storage (in GB), the size of the disk attached to each Query Engine node, and the number of service instances (BI Server, Query Engine, and Web Portal) configured for the Kyvos cluster.

  3. Click Create. The Create Kyvos Core Service Nodes (Azure Marketplace) dialog box is displayed. 
    Please note that the dialog box to create Kyvos Core Services for each Marketplace deployment may vary.

  4. Enter the number of nodes for Query Engines, BI Server, and Web Portal service that you want to create. enter your Kyvos Manager password to create the node.
    NOTE:

    • Enter the Instance Group Name (GCP) to add Web Portal Service on the cluster where Kyvos Services have already been installed. After adding the instance group name, click Validate. 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.

  5. 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. 

Terminating Kyvos Core Service Node for Marketplace 

Similarly, you can delete a node for Query Engine, BI Server, and Web Portal by clicking the three dots, and then click Terminate > Kyvos Core Service Node.

Click Terminate. The node will be terminated. 

Important

  • After deleting the BI Server, Zookeeper must be removed before redeploying it. You will see the following message after the deletion.

  • Click Remove. This will take you to the Zookeeper Configuration page.

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.

  1. On the navigation pane, click Kyvos and Ecosystem > Overview.

  2. 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.

  3. Click the three dots, and then click Add > Query Engine Node Disk.

    image-20240416-112638.png

    The Add Disk on Query Engine Nodes dialog box is displayed.

  4. 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

  1. To remove the disk from the Query Engine node, click the three dots and then click Delete > Query Engine Node Disk.
