I understand you want to create a cluster of denodo instances and access them via a load balancer. I have found this Denodo document on [Denodo Platform Cluster Architecture](https://community.denodo.com/kb/en/view/document/Denodo%20Platform%20Cluster%20Architecture) that might be useful here.
For the setup, you can refer to the Denodo documentation on [Hardware Requirements](https://community.denodo.com/docs/html/browse/latest/en/platform/installation/preinstallation_tasks/hardware_requirements/hardware_requirements#:~:text=The%20Denodo%20Platform%20can,of%20the%20Denodo%20Platform.) where you can find more information. Note that you should be careful with the memory commitment you will be choosing, as you do not want to exceed the limit of the physical memory.
Hope this helps!
