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 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.

	AWS Managed Services	AWS Marketplace	AZURE Marketplace	GCP Marketplace
Create Node (Query Engine)
Terminate Node (Query Engine)
Increase Query Engine Disks
Decrease Query Engine Disks
Show Query Engine Disk / storage size
Create Node (BI Server)
Terminate Node (BI Server)
Show BI Disk / storage size
Create Node (Web Portal)
Terminate Node (Web Portal)
Add Kyvos Reporting Service Node
Create Kyvos Reporting Service Node
Delete Kyvos Reporting Service Node
Terminate Kyvos Reporting Service Node
Add Kyvos Core Service Nodes
Delete Kyvos Core Service Nodes

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 a node for Marketplace
Terminating a node for Marketplace
Adding a disk for Marketplace
Deleting a disk from Marketplace
Creating Kyvos Reporting Service
Terminating Kyvos Reporting Service
Creating a node for AWS Managed Services
Terminating node for AWS Managed Services

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 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.

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; 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.
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.
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.
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.
