Cluster Wizard vs Node Client : What’s the difference, and which one should I use?

Cluster Wizard provides a full set of features, including complete VM life-cycle management across multiple hosts with full support for Ceph block storage, user management for multi-tenancy, and host network management for multiple hosts.
Node Client is a lightweight control plane interface for direct node management, offering complete VM lifecycle management across multiple hosts and host network management as well.
Node Client is ideal for small-scale clusters where multi-tenancy is not required, particularly in Edge Computing and SMB environments, while Cluster Wizard is designed to support to a wide range of environments, including large-scale clusters and complex multi-tenant infrastructures.

How can I obtain a license?

You can obtain a license :

• Cluster Wizard : send a request via Request License
