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.
