Note: The Virtual Load Balancer has been updated to Cent OS 7.6 as of April 30th, 2020. Due to the OS change, the Load Balancer will have to be redeployed using the latest VMDK and OVF file to update to the latest version.

The Virtual Room Connector Load Balancer can be deployed with multiple Virtual Room Connectors, for large scale deployment. Once the load balancer has been deployed, it can be used as the dial-in address for H.323 and SIP calls for Zoom meetings.  

The Virtual Room Connector Load Balancer is packaged as an OVF and can be deployed onto any virtualization platform that supports OVF including:

• VMware VSphere, VMware Workstation, VMware Fusion
• Nutanix (validated on Nutanix AHV and ESXi (AOS 5.5.5))
• Windows Server 2012/2016 Hyper-V (best-effort support)
• Virtual Box (best-effort support)

For more information, please see the system specifications for the load balancer.
