Meeting Connector Core Concepts Follow


Zoom offers a public or hybrid cloud service. In the hybrid cloud service,  you deploy meeting communication servers known as the Zoom Meeting Connector within your company's internal network. In doing so, user and meeting metadata are managed in the public cloud while the meetings are hosted in your private cloud. All meeting traffic including video, voice and data sharing goes through the on-premise Zoom Meeting Connector. 

The Zoom Meeting Controller is packaged as an OVF and can be deployed onto any virtualization platform.  

VM Types and Processes

There are two types of VMs in the Zoom Meeting Connector: 

  • Zone Controller VM
  • Multimedia Router VM

In the Controller VM, there are two server processes:

  • ZC, stands for Zone Controller
  • MMR, stands for Multimedia Router 
In the MMR VM, there is one server process:
  • MMR, stands for Multimedia Router


The simplest Meeting Connector set up is with one Controller VM deployed. 

For high-availability,  you can deploy another Controller VM.

  • If the ZC process in Controller 1 is down, the other ZC process in Controller 2 will take over automatically.

Each MMR process supports up to 350 concurrent meeting participants at the same time. That is, if you deploy one Controller VM, your Meeting Connector supports 350 concurrent participants and up to 250 meetings. If you deploy another Controller VM for High Availability, your total capacity increases to 700 participants and 500 meetings.

You can also deploy additional MMR VMs and link those to the Controller VM, to increase the participants capacity.

  • In one Controller VM, you can deploy up to 200 MMR VMs.

Networking Schema

The Meeting Connector uses the public cloud for the following services:

  • Notification Services for meeting invitation notifications on mobile devices and PC
  • Web Application Services for user and meeting metadata such as  login, scheduled meeting list
  • Cloud Controller for syncing meeting status

Note: SSL is enabled by default on the VMs, and will use SSL Encryption for network communication.
